1、KI-1681 CTL1 ChronoCom TL Telephone Interface Module Planning and Installation RAULAND-BORG CORPORATION ? 3450 West Oakton Street, Skokie, Illinois 60076-2951 ? (708) 679-0900 General Information Description This module enables an individual DTMF telephone or an electronic key system to control a Ch

2、ronoCom TL communications system. The telephone user can dial in- dividual rooms, answer call-ins by pressing a single push button, and use the keypad to select paging zones and distribute audio programs. Room stations can have non- dialing telephones as well as speakers. Refer to the attached wirin

3、g diagrams for the descrip- tions given in this section. “D” and “S” Series Systems In both “Dial-up” and “Switch-bank” Systems, all the above functions can be controlled by a DTMF telephone. In “Switch-bank” Systems, room-selector panels offer a ond way of distributing audio programming and pro- 6

4、two inputs for audio program sources. Related Equipment The CTLl module is meant to extend the functions of a ChronoCom TL communications system. The enhanced functions also require some additional equipment. Parts Supplied The module comes with the following parts: Two EPROMs labeled “U1” and “U2.”

5、 These replace the standard software chips in the 2524 Master Clock and Intercom Controller, to add the CTLl telephone functions. Four stand-offs (feet) with adhesive tape for sur- face-mounting the module. A 34-pin flat cable and two connectors, for linking the module with the 2524. In early units,

6、 these came unassembled. Standard System Equipment 2524 Master Clock and Intercom Controller: This provides the basic control functions for intercom as well as full master-clock functions (updating secondary clocks, ringing bells, providing music during class changes, and controlling lights and equi

Speaker-Control Panels: Rauland switch and relay panels can each handle 25 room stations. In “D” Series systems, TC4130 rack-mount rel

8、ay panels switch room speakers individually for intercom functions, and in groups for sending pages and distributing audio programs. In S” Series systems, which can control program dis- tribution by manual switches as well as by dialing, use a combination of SW25 switch panels and TC4110 relay panel

9、s. The SW25 has a three-position toggle switch for each room, which allows the manual selection of two different audio sources. Important: Be sure to set the DIP switch in each TC4110 or TC4130 panel (see the 2524 installation man- ual, KI-1628). Intercom Amplifier: The Rauland TC4160 Voice- Control

10、 Module (VCM2) enables a telephone to talk with a room speaker. The VCM2 is normally in the “listen” mode, so that the administrative telephone can hear the room. However. when the administrative telephones user begins speaking into the mouthpiece, the VCM2 automatically switches to the “talk” mode.

11、 Only one mod- ule is needed in a system. Administrative Telephone: The CTL1 will accept one line for DTMF telephones. This line can serve a single DTMF (dual-tone, multiple-frequency) phone, or it can accept a line from the trunk port of an electronic key system. Display: To give the user essential

12、 feedback (the num- ber of a room calling in, zones selected, etc.), each con- trol telephone should have a display. A TC4200 Vacuum Fluorescent Display can be mounted on a wall. where its large, bright display can serve more than one telephone (see N-1460). Alternatively, TC4220 Digital Displays ca

13、n be attached to individual telephones (see KI-1590). Con- sult these manuals for the limits on both the number of displays that can be used and on their distance from the central system. Power Amplifiers: Sending paging announcements requires a power amplifier capable of driving all room speakers a

However, privacy switches cannot be used on standard TL systems, because the privacy function has been replaced with the staff-telephone call-in function. Adding the privacy function to a system without s

16、taff tcle- phones requires an internal modification to the PC board (contact Rauland Sales Engineering). Audio Program Sources: Almost any program source that can drive a standard “auxiliary” input can be used. A versatile choice is the Rauland MCX300 AM/FM Tuner and Tape Cassette Player. This unit

17、comes with its own power supply and is designed for rack-mounting. Each program channel requires its own power amplifier. As explained in the preceding subsection. the amplifier used for paging doubles as the “A-Channel” program amplifier. MTG100 Multi-Tone Gcncrator: The CTL1s built-in chime-tone g

18、enerator provides a class-change signal. The MTGIOO will supply this tone and three additional tones (e.g., European siren) that can be sounded at will by di- aling the appropriate code. Room Stations A speaker enables a room to carry on two-way conver- sations with the administrative telephone. Eve

19、n if staff telephones arc used, speakers are needed to signal calls. Any of Raulands standard room speakers that have trans- formers and center-tap connections can be used. Repre- ntative B examples are the US0188 eight-inch speaker d the RS505 speaker module. A normal call-in can be sent by either

It is recommended that you install a 1342 Limiter Module across the “T” and “R” terminals of each staff te

21、lephones modular jack. This will protect the users hearing: incorrect wiring or a fault (a short or an open) could create an unbalanced audio tine, which, in turn, could cause an excessively loud sound in a telephone receiver during paging or tone signaling. Aside from the privacy switch, which cann

22、ot be used in standard TL systems, you can follow the room-station wiring diagram (KMl0l4) in the 2524 installation manual W-1628). Cabling Flat Cables: As stated in the parts list, the CTLl comes with the 34-pin cable and connectors. Note that this cable must be no longer than 1 feet. The relay pan

23、els come with 26-pin connectors, but the customer must supply the flat cable. All these panels should be daisy-chained on this cable. Speaker and Telephone Lines: Use a twisted pair and a single conductor in an overall shield. The room-sta- tion wiring diagram (KM1014) in the 2524 installation manua

24、l lists the maximum lengths for the common wire gauges. Display Cables: Use a shielded pair, and observe the distance restrictions listed in the pertinent display manual. Installation Most of the information needed is on the attached wir- ing diagrams. What follows here is additional information. Lo

25、cation The CTLl board has to be close enough to the 2524 for the 18-inch flat cable to link the two units. This means placing the module on top of the 2524 or next to it, on the inner side of the rack. Place the module away from sources of magnetic radiation, such as large power trans- formers. The

26、four plastic stand-offs snap into the corner holes of the board. Peel the protective plastic sheets from the bottom of the feet, then press and hold the board in place for a moment. to allow the adhesive to take hold. Carc- fully align the module before touching the feet to a sur- face, because they

27、 hold firmly once they have contacted a surface. Program Chips Replace the two program EPROMs o n the 2524 PC rd with the U1 ”and U2 chips supplied with the 1 (see the attached IL0360). Programming What follows is the special programming required by the TL system. For the rest of the intercom progra

No Rcmotc Phone or Monitoring or Auto-Answering Since a TL system cannot have a remote telephone, use the monitoring function, or auto-answer priority call-ins, the system will ignore any programming for them.

RP1, to the right of the terminal strip (as viewed frorn the rear), adjusts the output of the built-in pre- amp, which is used for paging functions. 4 RP2, to the left of the terminal strip (as viewed from the rear), adjusts the output of the built-in chime- tone generator.
