1、KI-1237A TZC25 and TZC25 Time Panels Installation RAUDBQROCOWOFIATIQN l 3450 West Oakton Street, Skokie, Illinois 60076-2951 l (847) 679-0900 Preliminary Description The TZ25 Time Zone Panel works with any of the selector switch panels used in Director Series Systems to connect remote room speakers

2、for time-tone signaling. The TZC25 Time Zone Panel is similar to the TZ25, except that it is designed for rack mounting and is used without a selector switch panel. It is primarily used for special functions in TelecenterSecurity Systems. Time Signaling A ground signal from the zone relay contacts o

3、fa program- mable clock, such as the Rauland 2424, is the “ Z” input to the Zone Patch Panel for time-signal distribution. The output of the Zone Patch Panel to the “ R” connector on the TZ25 energizes relays for the selected remote station in order to send the time tones there. A TCMS time-zone osc

4、illator plus a suitable power amplifier supplies the time signal to the “ S” connector on the TZ25. Bracket Modification equipment such as the TW25 Two-Wire Adapter can be plugged onto the terminals (“ piggy-backed” ). .,.,. .I As was announced in Tech Bulletin no. 191 (June 25, In factory-wired sys

Refer to the attached IL0269 for the following steps: Step 1. Remove and set aside the two sheet-metal screws that secure the board-support bracket to the side b

7、rackets. To connect the field wiring directly to the TZ25, refer to the wiring installation procedures below. Step 2. Rotate the support bracket 180” vertically: the card holders will still face frontward but the tabs that fit against the side brackets will now be on top. Cable Requirements Step 3.

8、Rotate the support bracket 90” axially, so that the tabs now point to the rear and the card holders face upward. A shielded cable with one twisted pair connected to ter- minals E and D and the shield connected to terminal G is required for each remote station. Terminals T, A, and L are used only whe

9、n the selector switch panel has call-in circuitry. The T terminal requires a third wire to the station. Step 4. Unsnap the card holders, then snap them into the adjacent holes in what is now the rear side of the support bracket. Step 5. Use the two screws that you set aside in Step 1 to re-secure th

10、e support bracket to the side brackets. Use 22-AWG solid conductors. The diameter of the indi- vidual wires, including insulation, should not exceed 0.095 inches for insulation-piercing connections. The field wiring must be totally supported with cable ties or clamps secured to the chassis cut-outs

11、or extrusions. L . . . . . . . / Output Connections Both the TZ25 and the TZC25 are equipped with 110 square-pin terminals on the rear edge of the printed circuit board. The field wiring can be connected directly here, or Wiring The connections to the panel s rear terminals may be made by insulation

13、he Rauland SK-2522 includes 25 connectors. See the attached manual, KI-1564, for installation instructions. Modified Wire- Wrapping You will need a wire-wrap tool such as the Gardner-Den- ver Model 144-1C or Model A-205577-31. Step 1. Strip back the cable sheathing and the shield about 1 V2 inches f

14、rom the end of the cable. Step 2. Strip back about one inch of the insulation on the individual wires. Step 3. Use a wire-wrap tool to wrap each bare wire around the appropriate terminal; be sure to add one complete turn of the insulated part of the wire as a necessary strain relief Leave about two

15、inches of slack in each wire to accommodate possible future connections. . . . . . . . . . . . . . . . # Crimped Connectors The Rauland CTA25 Terminal Adapter Kit consists of25 four-terminal adapter housings and 100 crimp connectors. To make good connections, use a Molex Model HTR-2445-A crimping to

Strip about t/a inch of insulation from each indi- vidual wire. Step 3. Use a crimping tool to fasten the wires to the connectors. Step 4. Insert the connectors in
