MOUNTING

Arrangements must be made for the installation of a
standard voice-grade telephone line (touch-tone or
rotary, telco or PBX Port), 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

When selecting a mounting location,

Trigon recommends some shelter be provided from
direct rain and sunlight. An overhang is usually
sufficient. If a heater element is installed, be sure to use
a bi-metal thermal switch to prevent over-heating during
the summer months. Pull the wiring through the access
hole in the lower portion of the back plate (Fig. 2). Bolt
the plate to the surface through the four .312" mounting
holes provided. At this time, the wiring should NOT be
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).

WIRING

1. Use the wiring diagram on pg. 5 for wire connection

information.

2. Do not energize wires until installation is completed.

3. 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, 20VA, 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.

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 for both the power

and telephone cabling. Ground the cable's shield to
the same point as the unit and filter. To avoid ground
loops, do not ground the shield at both ends. Use
600V insulated wire for this installation.

7. Isolate the 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. Primary Relay is a 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 output relay, and deactivates thirty
seconds after relay release.

10. (OPTIONAL) 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.

12. Apply power to the unit.
