Thismanual contains the information required toinstall
and program the TRIGON Miniguard IID. If you are
using this manual to install this unit, it is very important
to read all the sections in order.
You should read these instructions before you begin
installation. This will insure that everything is done
efficiently.

TheTrigon Miniguard IID is a handsfree, multi-number
Telephone Entry System for resident/visitor control.
Visitors contact the desired tenant by entering a simple
directory code gained from the built-in electronic
directory. Following a two way voice communication,
the resident then grants or denies access.
TheMiniguard IID hasa capacity ofupto 400 telephone
numbers, up to 400 personal entry codes, up to 1600
data codes and is PBX Analog Port compatible. It is
constructed for rugged outdoor use. Its long-lasting
brushed-finish stainless steel housing complements its
thin design lines.
The Miniguard IID is available in surface mount,
weather mount, and flush mount. The weather mount
version is intended for use in open weather conditions
and comes standard with an LED lighted front panel.
The surface mount has a lower profile and is intended
for more protected locations. The flush mount utiizes
the wall mount front box and a flush mount back box
with a .75 inch trim ring.
The Miniguard IID is equipped with valuable features
and options that provide a wide range of guest and
residentcontrol options—doors, gates,security lighting,
and more.
Two output relays are available to control a variety of
securitydevices. Recordsof all access activityarestored
in log memory, for downloading via direct connect or
modem.
Note: Printer log output is disabled in order to support
TriCom-Pro modem interface.
The Miniguard IID supports Trigon’s TriCom-Pro
protocol. TriCom-Pro is Trigon’s universal database
handler and communications package designed to run
on most standard IBM compatable PCs using Windows
98 or greater.
This software link is achieved via a 2400 baud, full
duplex modem, or direct 3-wire RS-232 connection
using a null modem cable.
The Miniguard IID’s data base can also be edited via
the display and keypad on the face of the unit.
If you are using this manual as a programming guide
after the initial installation, you may find the TABLE
OF CONTENTS useful in locating the particular
programming procedure you need.

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 40VAtransformer. 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. "RS232 direct connect" cable from computer
(Computer 9-pin RS232 pin 3 connects to terminal
"IN", pin 2 connects to terminal "OUT", and pin 5
connects to terminal "COM". Short pins 4, 6 and 8
inside 9-Pin D-sub..
..
.
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.

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
mountinglocation as possible. Thetelephonecompany
may require the following information.

When selecting a mounting location, Trigon
recommends some shelter be provided from direct rain
and sunlight unless the surface mount model is used.
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
willtemporarilyblacken the crystals makingthedisplay
unreadable. Atabout 10degrees fahrenheit, the display
will become sluggish. If a heater element is installed,
besure to use abi-metal thermal switch topreventover-
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. Bottom feed is also available on the surface
mount and wall mount models.
* We offer an optional Lighted Hood that helps
with weather protection for the wall mount
model.

Remote Operation Time-out:
If you call the unit to operate it remotely, you have 30
seconds until auto-termination. Any tone instruction
will restart this 30 second timer. If you find that you
need more than 30 seconds:
1. Enter "8” on your telephone’s keypad to extend
your call time to three minutes.
Remote Function Tests:
The TRIGON Miniguard IID has the ability to run a
series of self-tests to verify its functionality.
Call the unit. When it answers choose from the
following.
1. Enter "0” for touch tone echo test.
Unit will “echo” any touch tone you send with your
phone.
2. Press " # " to escape from this test.
3. Enter "1" for memory test. (One tone = good;
two tones = bad).
4. Enter "2" for touch tone sequence. (Unit
answers by transmitting touch tones 1 through 9,
*, and #).
Printer Operation: (Optional)
The Miniguard IID can support an audit log output to a
remote serial printer up to 300 feet away.
The printer must be a SERIAL type with a standard
RS232 interface connector. The settings of the printer
are:
300 Baud, 8 bits, No parity, 1 stop bit.
Serial linkage requires a minimum of three wires that
carry “DATA, COMMON, and BUSY”.
