MOUNTINGMOUNTING
MOUNTINGMOUNTING
MOUNTING
Arrangements must be made for the installation of a
standard voice-grade telephone line (touch-tone or
rotary, telco or Analog 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. It is
critical on units that support an LCD display, that they
be mounted so that direct sunlight NOT be allowed to
fall on the display itself. Like all LCD displays, heat
absorption will temporarily blacken the crystals making
the display unreadable. At about 20 degrees fahrenheit,
the display will become sluggish. 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
surfacethrough the four.312" mounting holesprovided.
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).

weather protection

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 ModelAPF 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 cables 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.Output 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 output relay, and
deactivates thirty seconds after relay release.
10.Connect printer wiring to the RS-232 port (Printer
OUT to RS-232 IN, 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.

The process follows the instructions outlined earlier in
the PROGRAMMING Section, with a few exceptions
as stated below.
Thefollowing conventions areused to describe thesteps
in the programming:
Data between { } is a mandatory program key stroke
sequence. Data between [ ] is to be supplied by the
programmer. Unit responses are shown between ( ).
(P) Basic Programming of the Unit:
Call the unit. It will answer and acknowledge same by
sending a long tone.
Note: Any resident code(s) and telephone number(s)
must be programmed into unit prior to entering the
display editing mode (see programming section pp. 7).
When all other programming is complete, proceed with
display editing.
(Q) Editing the display:
1. Unit must be in Program Mode(see sectionA),
2. Press [#,92] to enter the display edit mode.
You will hear two beeps.
3. Press the resident code to be edited.
You will hear one beep.
4. Enter the resident's name by pressing a two
digit number for each character to appear on the
display. The name entry may be up to 16
characters. Use the numbers from the Character
table that follows.
Note: If modifying a name, simply overwrite the
existing name. Use spaces if necessary to
overwrite the remaining characters of a previous
name that was longer.
5. Press [#] to end the editing of that line.
You will hear two beeps.
6. Repeat steps 2 to 5 to edit another name.
7.To stop editing, hang up the telephone you have
been using. The Miniguard IID will time out and
reset itself after the unit's call length time setting
has elapsed.
