WIRING

MOUNTING

avoid ground loops, do not ground the shield at both

ends. Use 600V insulated wire for this installation.

7. Isolate the Telco phoneline from 12 VAC power

wires. This will prevent 60 Hz hum from occurring
on the phoneline. Use 22 AWG wire on Telco line
run distances of up to 2400 feet. Consult the factory
for distances greater than 2400 feet.

8. Power Relays 1 and 2 are dry contact, Form C type,

rated for 5 AMPS @ 30 VDC/ 250VAC.

9. The Shunt relay is a low-power (4 watt) reed relay.

It can be used for temporary alarm switch bypass,
video camera activation, etc. The Shunt relay
activates with the #1 or #2 power relay, and
deactivates thirty seconds after relay release.

10. Connect printer wiring to the RS-232 port (Printer

IN to RS-232 OUT, Printer BUSY to RS-232 DSR,
Printer COM to RS-232 COM).

11. If all wiring and grounding is completed, mount the

faceplate onto the backbox.

1. Use the wiring diagram (Fig. 3) for wire connection

information.

2. Do not power any other device from the Trigon’s

12 VAC transformer. If a substitute transformer is
used, be sure it is rated 12 VAC, 40VA, UL Class 2
listed. The 12 VAC input power wires should be
18AWG, 600V, insulated wire. This should be
sufficient for distances up to 200 feet.

3. Do not energize wires until installation is completed.

4. Ground the unit by attaching a separate 12 AWG

ground wire to the ground location on the terminal
block. This ground wire should go to a grounding
rod or grounded metal conduit.

5. Trigon recommends that an EMI filter (Cornell-

Dubilier Model APF 1021 or equivalent) be mounted
between the 12 VAC transformer output and the unit.
EMI/RFI filters are available from Trigon. Mount
the filter as close to the unit as possible. Ground the
filter to the same point as unit ground.

6. Shielded cable is recommended. Ground the

shielding to the same point as the unit and filter. To

Arrangements must be made with the local telephone
company for installation of a standard voice-grade
telephone line (touch-tone or rotary) as close to the unit
mounting location as possible. The telephone company
may require the following information.

FCC Registration No..................1Z8898-62546-DI-T

Ringer Equivalence..............................................0.8B

Connector............................................Terminal Block

The unit is designed to be as weather resistant as
possible*. We do however recommend some shelter
from direct rain and sunlight. An overhang is usually
sufficient. Bolt the back plate (Fig. 2) to the mounting
surface using the four .312" holes in the chassis. Feed
the wiring through the access hole in the rear of the
back plate. At this point, the wiring should NOT be
live (energized).

Note: If used in extreme weather, a bead of silicon
sealant should be run around the outside top two thirds
of the unit, after the front case is secured.

(Fig. 2b).

* We sell optional Lighted Hood that helps with weather
protection
