PRODUCT OVERVIEW
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.
This manual contains all the information required to
install and program the TRIGON MINIGUARD HF-2.
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.
The TRIGON HF-2 is a multi-number auto dialer.
Uponpressing the button,the HF-2dials aprogrammed
telephone number. If the number dialed is busy or does
not answer, the HF-2 will hang up and dial the next
programmed number, up to a maximum of 10. If the
last programmed number is busy or does not answer,
theHF-2 will rollover andstart the dialingprocess again
with the first phone number.
The HF-2 comes standard with 2 output relays. These
relayscan be programmed to operatein several different
ways. Relays can be set to pulse momentarily for
camera call-up, they can be set to stay latched on for
the duration of the call, or they can be set to operate for
a timed duration (for door strike operation, etc).
There are two Modes of Operation incorporated in the
HF-2:
1. The Standard Mode provides timed closure
of the relays and is typically used for telephone
entry.
2. Optional Ring Down Mode:
When call call button is pressed, the HF-2 seizes
the telephone line and waits for the PBX to dial a
preprogrammed number.
A Site I.D. code feature provides for unit identification.
The Site I.D. code is a programmable four digit code
that is transmitted by the HF-2 when it receives a
command from the called party. This code, when
interpreted by a Trigon DTMF Decoder, will identify
the calling unit.

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. 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).
10.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 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. 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, or utilize the knock-out on the bottom to
feed through conduit when access through the back wall
is not workable. 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). Trigon also sellsan optional Lighted Weather
Hood that should be used if the unit is exposed to direct
weather.
