Associated Equipment This list is representative only. The 2524 is designated to be highly flexible.
12、Therefore, it is nor practicable to list every possible application in this manual. What is listed. the attached wiring diagrams. and the descriptions of the outputs should cover most applications and give you some ideas for working out special installations. Clock Equipment Secondary Clocks: The 25
13、24 can correct all of Raulands secondary analog and digital clocks. It can also correct all of the widely distributed clocks from other manufacturers (see the list and the wiring diagnms at the end of this manual). Finally, you should be able to pro- gram a special correction code for virtually any
14、other clocks that are not handled by the standard codes. Clock Power Supplies: Raulands 2415 24-VAC and 2416 120-VAC Power Supplies can handle up to 25 sec- ondary clocks per unit. Buffers: The 2524s outputs each have a relay that an handle up to five amperes of current at up to 120 VAC or 30 VDC. S
15、hould the equipment you connect to a given output require more power, you can accommodate it by using buffers. The 2418 AC Buffer an switch up to 10 amperes at 110 VAC, and the 2419 DC Buffer an switch up to five amperes at 60 VDC (the higher voltage is nccdcd by minute-impulse clocks). Wiring two o
16、r more buffers to split the load increases the total load that the output can handle 2417 Correction Module: This is used to enable the 2524s “DIG” output to control a power supply with up to 25 digital secondary clocks. Intercom Equipment Director Control Panels: The combination of the 2524 and a D
17、irector intercom system provides a sophisti- cated communications control ccnrcr. The inrcrcom pan- els enable the user to talk and listen to rooms. and to distribute program material (from optional program sources and over optional power amplifiers). The 2524 shows all-ins on its display, enables t
18、he user to dial rooms on its keypad, and provide software zones for paging (and time tones). All of the station-related func- tions also require optional speakcr relay modules and room speakers. Speaker Relay Modules: These panels carry out the zoning and calling commands from the 2524 by conncct- i
19、ng the proper rooms. The TC4 130, like the TC4 120 (SCC25), has a chassis for rack-mounting. The TC4131, like the TC41 l0 (SC25), is designed to be mounted on the back of Rauland switch panels , such as the SW Series. Telephone: A CRT3 Staff Telephone can bc used for communicating with room stations
20、 and paging The 2524 will show call-ins on its display and signal them with “beeps.” Again, this requires optional relay modules for tching the speakers on. Also required is a TC4160 CM2 Voice-Controlled Module) which is an amplifier unir that automatically switches from listen to “talk” when the te
21、lephone user begins speaking. For a more complete display of all-ins (and for a remote Iocation), install a TC4200 Vacuum Fluorcsccnt Display. See the attached wiring diagram KM0983. Music: T h e 2524 an distribute a program or music source connected to its Program” input for continuous listening. I
22、t can also distribute a program source con- nected to its “Music” input as part of a class-change event. Besides the relay modules and room speakers, this re- quires a program source, such as the Rauland MCX300 Tuner and Tape Cassette Player, and a power amplifer. Output Terminals In the following d
23、escriptions, the 2524s rear terminals are described in order, from left to right as viewed from the rear of the chassis. In-Gnd-Out: These four wire-wrap terminals (there are two “GND” pins) an be wired to a standard RS-232 cable and connected thence to a computer or a modem for remote programming,
24、or to a serial printer to provide a log of intercom activities. event execution, and faulty lines (see the sample log below). For the wiring to the cable, see the attached KM0991. RPl: This potentiometer must beadjusted for the 2524 to respond to all-ins (see Calibrating RP1” in this man- ual). SC25
25、: This 26-pin connector must be connected to all optional speaker relay panels in the system. It conveys the data for switching the speaker relays.

However, if the customer wants to use a different program source for program-distribution and the music associa ated with clock tones, connect a separate music amplifer and source to these terminals. arc wired across the phones hook switch (use the “Aux” terminals on the CRT3).
31、lifting the handset will immedi- ately connect it to the caller. It is also necessary to keep the “Reset” terminal (described next) connected to a circuit common throughout the communication. See the attached KM0983. Reset: This must remain connected tO a circuit com- mon while the remote phone is p
32、aging or in communica- tion with a room station. Connect this input and a ground terminal across the hook switch of a remote phone (the Aux terminals on a CRT3 Staff Telephone). Note that this output is active when it is high: it disconnects the paging and intercom amplifiers and releases the speake
33、r relays unless it is grounded. See the attached KMO983. Page In: Momentarily connecting this input to a circuit common instructs the 2524 to connect a remote tele- phone to all room stations for an All-Page announcement. This takes precedence over the “Answer” terminal. Thus, if “Page” and “Answer”
34、 are grounded simultaneously, the 2524 will arty out the page and ignore the answering function. If the remote telephone is in communication with a room station, pressing the Page button would disconnect the room and engage the paging function. It is also necessary to keep the Reset terminal (descri
35、bed immediately above) connected to a circuit common throughout a page. See the attached KMO983. In: Connecting another master clock here enables it to control the time in this unit. When the 2524 receives a valid synchronization signal from another Rauland master clock, it changes its time to 12:01
36、 a.m. Gnd: This is a circuit common, which also serves as the ground. S-Bus: These screw terminals are for the balanced 25-volt speaker audio lines. They must be connected to the S-Bus terminals of all the optional relay panels in the system. Refer to the attached wiring diagrams for more details. I
37、C Amp: Connect the intercom-amplifier output of an optional Director master control panel to these screw terminals. The 2524 can then internally connect this audio to the S Bus, which runs from it to the optional relay panels. Refer to the attached KM0983 and KM0984 for more details. A Amp: These sc
38、rew terminals are used to receive the output of the “A” Channel amplifier. The 2524 internally connects this to the S Bus for program-distribution and paging functions. Rcfcr to the attached system wiring diagrams for more details. Music Amp: Connect the output of the music amplifier to these screw

40、t is used to control an optional external relay when there is a remote phone (see the attached KM0983). When a clock event calls for music after a tone, this terminal is internally grounded, which activates the external relay (see the Music Amp” termi- nals, above). Beep: The 2524s built-in Sonalert
41、 beeper will signal all-ins. If a signal is desired in another loation (e.g., by a remote phone that does not have an associated TC4200 display), the 2524 an also drive an external 6-VDC Sonalert type of sounding device. Connect the devices positive lad to the “Beep” terminal and its negative lead t
42、o a ground terminal. Busy: These outputs an used to connect an external indicator (LED, lamp. etc.), which could be used by the remote phone to show when the 2524 is being used for communications or programming. The device will be ac- tivated whenever the front-panel keypad is used. and will remain
43、on until that function has ended. The “+ terminal an provide up to 45 milliamperes of current. Page Out: This output is wired to a Director master control panel when a remote phone is installed (see the attached KM0983). When the remote phone performs an All-Page, the 2524 connects this output to th
44、e circuit common. This, in turn, causes the master control panel to feed the remote phones audio into the “A” Channel amplifier. +5V This output an be used as an auxiliary power supply (5 Vdc ,1OOmA). Its most common appliation is to power a 2417 Correction Adapter Module, which is used with the DIG

48、The 2524 is designed for mounting in a standard 19. inch rack. No special treatment is required if other equip ment is mounted next to it. Step 1. Locate 3 inches of nckspacewhcre 2524 will be mounted. Slide the four supplied # 10 Tinnerman clips over the mounting holes in the channel rails. (If the
49、 channel rails holes are tapped, do not use these clips.) Step 2. Prepare the mounting screws by placing a black flat washer and then a fiber washer over each one (all supplied). Step 3. Position the 2524 in the rack, align its front- panel mounting holes with the Tinnerman clips, and use the four prepared machine screws to secure it to the channe1 rails.
