The system shall be an electronic, microprocessor controlled system (Ring- Communications part number RM5000EX). The system shall be modular in design, and the central processing unit (CPU) shall be expandable to 56 station capacity in increments of eight subscribers per plug in printed circuit board. There shall be no direct limitation to the number of stations reporting to a master. System shall be capable of expansion beyond a single stage. The configuration of master stations shall be interchangeable without the need to change out other existing equipment. The system must be capable of mixing and matching any number of master stations and sub-stations, by simple programming the CPU. The CPU shall support three simultaneous conversation paths for the 56 station capacity and shall be field programmable for such features as: speed dialing, access to all call, group call(7), direct access dialing, etc. Battery back up shall be a standard feature for systems with 25 stations or more. The lobby/security annunciation panel (Ring-Master part number DAD104, complete with AA type master station) must have an audible and alphanumeric visual annunciation from the calling sub-stations. The annunciation panel shall provide 4 rows of 12 characters each to identify the calling party's location. The panel shall also be capable of distinguishing up to nine (9) levels of priority call-ins from other master stations and sub-stations. It should be capable of desk or flush mounting. The annunciator panel shall offer a contact closure, to drive other devices. (i.e. strobe, beeper, or pocket page). The annunciator panel must also monitor the staff stations for shorts, opens or power interruption. The DAD104 panel shall have a queue counter, so that if more than four (4) calls are made simultaneously, the operator will be advised of those calls. These calls may be answered out of sequence. One hundred percent queuing of all calls must be possible. Any master station in the system may be assigned an annunciator. The annunciator/master station shall offer a transfer switch so that calls may be transferred to other operators. Calls shall be programmable to annunciate on one or multiple panels simultaneously and if one panel handles a call, all other panels are updated as to its status. The status indications shall indicate: "Call", "Busy", "Fault", "Park". It should be possible to interface to CCTV camera switchers via RS232 protocol or by a contact closure. The system shall be capable of being pre-wired with intercom jacks at strategic locations. Hot plug in of staff or master stations shall be possible. The system shall be capable of interfacing to the in house public address system(s) using the Ring model IF935 The sub-station (Ring-Master SS910,SS911,SS912,SS913 or SS900B, AN913) shall have a loudspeaker and a microphone to provide for crisp, clear hands-free communications. The SS900B stations may be mounted on a standard 4" speaker grill configuration behind a panel. The SS910 and SS900B stations have connections for external call in buttons. The SS910,SS911,SS912,SS913 shall be capable of surface or flush mounting. Call button(s) on the SS911,SS912,SS913 shall be built in. OPERATION A call shall be placed from the sub-station by depressing the call button. This action shall cause the alphanumeric annunciator panel to flash and sound a beep tone. The sub-station will provide for four outputs that can drive an external beeper,lamp or camera so as to comply with ADA. When the call is answered from the master station, the sub-stations' LED will change state and a pre-announce tone will be heard. When the annunciation master cancels the call, both stations will hear a disconnect tone and their LED's ,will extinguish. A. GENERAL 1. The system shall consist of intercom master stations, or master and substations, a microprocessor controlled, fully electronic central exchange, power supplies, wire, cable, hardware and accessory items - all as required for a complete and operable system. 2. The system shall provide two-way voice communication among areas as may be shown on the drawings. Operating features shall be as described hereinafter. The system shall provide both "hands free" and "manual" modes of operation. All stations shall have the same wiring requirements. Special features shall be assigned to specific system numbers and shall not require additional facility buttons on the station, nor any additional wiring. Every master shall be capable of calling every other station in the system. Cable requirement shall be two pair UTP(Unshielded Twisted Pair) connecting each subscriber and station and the central exchange. Where a special need exists (e.g. distantly situated buildings), it must be possible to reduce the number of wires per station to one pair, with the use of local power. 3. The system shall be capable of two, three or four digit dialing being selectable by DIP switch. 4. The system shall provide PC computer Programming capability to modify individual features and timers. All programming will be stored in a nonvolatile, battery backed RAM. 5. The system shall be equal in every respect to that manufactured by Ring- Communications. Catalog and model numbers are intended to indicate the quality of material and workmanship, as well as the exact operating features required. 6. The system shall operate and generate standard telephonic DTMF signals. (Dual tone multi-frequency). 7. Battery backup shall be available on all systems and shall be standard on systems with over 24 subscribers. B. OPERATION AND FEATURES 1. To place a call from a master station, the two, three or four-digit number of the desired party shall be dialed by pushbuttons. A connection tone shall be heard at both the calling and the called stations to signify completion of the connection. No further manipulation of controls shall be necessary until the conversation is complete. The connection may be cancelled by either party. 2. When calling a station that is in the "private" mode, a special signal shall be heard at both stations. The called party may accept the call by momentarily touching one button and then talking. The private station may also reject the call by depressing the "cancel" button. Upon completion of a conversation and the cancellation of the call, a station that has been operating in a private mode shall remain in a private mode without further control manipulation. A privacy switch shall be provided, such that a simple activation of the switch will activate the private mode. 3. All desk type stations shall provide the facility for both "hands free" and "handset" modes of operation in a one piece unit. In the handset mode, the loudspeaker shall be attenuated and when both parties to a conversation use the handset, the conversation shall become full duplex speech. HANDS-FREE/LOUDSPEAKING When two intercom stations are connected, either party may speak to the other hands-free without touching any buttons. CONFIDENTIAL/SOFTSPEAKING At anytime during the call, either one or both parties may pick up their station (i.e. AA916) and use it as a handset for a confidential conversation. When both parties are in handset mode, the system operates in open duplex mode and both parties may talk and listen at the same time. SIMPLEX The T-button may be used to control the speech direction (push to talk release to listen). This is useful when one of the intercom stations are in a noisy area. Either party may use this function. If both stations are pushing the T-button the control is given to the station that pushed "T" last. Either party may revert to hands-free mode by tapping the T-button. Any call number may be programmed with the privilege "simplex always". When a call is placed from or to a station with the "simplex always" privilege, the initiator will be in listen mode and the T-button must be used to change the speech direction. MICROPHONE CUTOFF To temporarily mute the microphone during conversation, the mute button (M) may be pressed down. DIRECT DIALLING It is possible to program keys 0 to 9 of each intercom station's keypad to speed dial frequently called numbers. When a programmed key is pressed, a dial tone is heard as normal. If a second key is pressed within a programmable subscriber timer, then a normal dial sequence is taken. It is possible to program one call number for each intercom station to be activated by DC-shift. This type of calling is used with door stations and elevator stations that do not have a tone dialer. REMOTE CONTROL DTMF tones may be sent from one intercom station to the other for remote control. The keypad on the station sends standard telephone dialing tones (CCITT). This is mainly used for electric door-lock release and for dialing out to the public telephone network (PTT). CAMP ON BUSY EXTENSION The caller may camp-on to a busy extension for 15 seconds (programmable subscriber timer), after which the call will be automatically cancelled. If the called party becomes free within this time, the connection will be established with warning tone to both parties. PRIVACY The stations privacy switch controls the privacy status. When the B- subscriber is in privacy, both stations get the ringing tone. The B-subscriber may accept the call by pressing the 0-button within 15 seconds (programmable subscriber timer). This operation is valid when the B-subscriber is not using personal queue. PRIORITY When a station is programmed with the privilege "Priority" it may connect to a busy or privacy station by dialing "0". This is only possible if the busy station does not have Priority privilege. PERSONAL QUEUE Each intercom station has a Personal Queue. This queue is activated through programming with privilege "Personal Queue". All received calls are then put in the personal queue and the intercom station will ring (2 seconds on and 3 seconds off) until the call is answered by pressing the 0-key. When the call is cancelled (X) the next call in queue starts ringing after 2 seconds (programmable subscriber timer). With the privilege "Automatic Answer" the call is automatically connected without pushing the 0-key. Calls are inserted to the personal queue on first in first out within each priority level (1-9). The priority level is the Call Priority of the calling station (level 1 is highest priority). The calling station may be connected to Ringing Tone, Program Channel or silence when in queue. The personal queue may be displayed and answered on a DAD104 or DS16 TRANSFER Call Transfer is used to distribute incoming calls to additional intercom stations. Call transfer is using the personal queue. Each subscriber may be programmed with up to 7 transfer numbers with programmable delays. When a call is placed to an intercom station with "personal queue" the call will be inserted in the personal queue of the called station. When the transfer 1 delay expires the call will be placed in the personal queue of the transfer 1 intercom station. The transfer 2 delay is then activated and when it expires the call is inserted in the personal queue of the transfer 2 intercom station. This sequence is then repeated for transfers 3-7, if programmed. The incoming call is now in the personal queue of multiple intercom stations and when one of them answer the call is removed from all the personal queues. The transfer delay is 0-9 minutes or infinite. If a transfer station is in privacy then the delay to that station is set to 0 and the call will transfer instantly (used for night transfer). Personal Queue privilege accompanies the transfer granting Personal Queue to the object station for the duration of the call. ALL CALL Allows for one way paging from any designated master station to all other stations in the exchange and will override other calls (they will reconnect when the All Call is completed). The initiating station must have privilege "All Call Access". The duration of the All Call is a programmable subscriber timer. The call number for All Call is 70. The All Call is terminated with X, or 8 for call back (meet me). One of the stations can then dial 90 to call back to the All Call initiator. The call back is active until a station dials 90 or a new call back is activated from another All Call or Group Call. It is possible to exclude receivers from the All Call. This is done by entering call numbers in the All Call exclusion group (group #0). GROUP CALL Allows for one way paging from any designated master station to a group of stations and will override normal calls (they will reconnect when the Group Call is completed). The initiating station must have privilege "Group Call Access". The duration of the Group Call is limited to 60 seconds (programmable subscriber timer). There are 7 Group Calls in the system with access call numbers 71-77. The Group Call is terminated with X, or 8 for call back (meet me). One of the stations can then dial 90 to be connected to the Group Call initiator. The call back is active until one station dials 90 or a new call back is activated from another All Cal or Group Call. Call number of the receivers are entered in the Group Call groups (group 1-7). All stations may be a member of multiple Group Call groups. Only one Group Call can be active at a time. Stations calling Group Call when it is in use may camp on until it is free. PROGRAM DISTRIBUTION The system has one program channel for distribution for music or other programs source. The access code is 98. The connection to program distribution does not effect normal intercom operations. When a call is initiated or received, the music is put on hold until the call is completed and then it automatically reconnects. TWO WAY RADIO The RM5000EX system may be connected to a radio base station for communication on a closed two-way radio network. An interface unit(Ring p/n IF935) is required and is given an ordinary subscriber number. If the radio system is simplex PTT then the subscriber number should be programmed with privilege "Simplex Always". The radio receive signal may be connected to the program distribution channel for monitoring. TELEPHONE NETWORK An interface can be supplied to operate between the public telephone network and the RM5000EX. The interface is used to make calls from any intercom station to the telephone network and to make calls from an outside telephone to any intercom station. If the interface does not have the privilege "Personal Queue" then calls made to the interface will not activate the dialer and the phone number must be manually dialed. If transfers are activated from other stations (masters), then these calls are automatically placed in the personal queue of the interface and will use the speed dialer out on the telephone line. This way a master may use the interface for manually dialed calls, while sub-stations that dial the master will be transferred to the personal queue of the interface and use the speed dialer. The master may have an infinite transfer delay during the day when all calls are answered by the master. At night the master is placed in privacy and all calls then are automatically transferred to the telephone interface. The IF934P interface may be used as a speed dialer to one telephone number used for answering intercom calls from Sub-Stations in a night transfer mode of operation. When a call enters the personal queue of the interface it will speed dial the remote telephone number, connect the station in queue to the telephone line and then wait for disconnect from the remote telephone before releasing the connection between the interface and the intercom station. After 2 seconds (programmable subscriber timer) the next call in personal queue will repeat the process. The DNA934P interface may be used as a speed dialer to a telephone number used for answering intercom calls from Sub-Stations in a night transfer mode of operation. It shall be capable of dialing up to 4 telephone numbers. When the call is answered on the remote telephone the DNA934P interface shall announce where the call is originating from and from which intercom station. The receiving party will then have the option to press 1 to accept the call or hang up. If the call is not answered in the preprogrammed amount of time or if the receiving party hangs up then the DNA934P shall dial the next programmed number. If only one number is assigned then it will redial that number. When the call is acknowledged the DNA934P will wait for disconnect from the remote telephone before releasing the connection between the interface and the intercom station. After 2 seconds (programmable subscriber timer) the next call in personal queue will repeat the process.
