INTRODUCTIONINTRODUCTION
INTRODUCTIONINTRODUCTION
INTRODUCTION
This manual contains all the information required to
successfully install and program the TRIGON
CastleGate III. If you are using this manual to install
this unit, it is very important for you to read all sections
in order.
You should read these instructions before you begin this
installation. This will insure correct installation.
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 needed.
The CastleGate III is a “No Phone Charge”, handsfree
telephone entry system for use at a single residence. It
has two distict operating modes:
1. The primary mode is where the Castlegate III uses
the resident’s existing TELCO telephone line for
communication and access control. Since gate calls do
not go through the telephone company network, there
are no charges for calls made from the system. In this
mode the resident's standard single line telepone is used
for both TELCO calls as well as calls from the front
gate.
2. The secondary mode is where the Castlegate III does
not use the TELCO line, but is wired directly from the
gate to the residence. In this mode either a separate
telephone must be available or a two line telephone at
each resident phone line outlet.
Visitors initiate calls from the entrance by pressing the
“call” button on the illuminated faceplate. The call is
received in the residence. The resident can discern
between entrance calls and regular telephone calls due
to the unique ring modes available in the Castlegate III
programming.
With up to 50 codes available, residents, employees, or
guests can access the premises immediately by entering
their personnal entry code on the CastleGate III’s
keypad.

MOUNTING
UsetheappropriateBackbox drawing (Fig.2) toprepare
the surface on which the Trigon is to be mounted. The
unit is designed to be as weather-resistant as possible.
The sides of the front plate enter rain gutters when the
front face is closed.
For surface mount versions:For surface mount versions:
For surface mount versions:For surface mount versions:
For surface mount versions: Bolt the
backbox to the mounting surface using the four 5/16"
holes in the chassis. Also, pull the wiring through the
access hole in the rear of the backbox. At this point,
the wiring should NOT be live (energized).
For flush mount versions:For flush mount versions:
For flush mount versions:For flush mount versions:
For flush mount versions: Prepare
rectangular hole 8.25 inches by 5.25 inches by 3 inches
deep. Pull the wiring through the access hole in the
bottom of the backbox. At this point, the wiring should
NOT be live (energized).
WARNING:WARNING:
WARNING:WARNING:
WARNING:
If a conduit is to be attached to the bottom of the
Castlegate III, be certain the conduit connector does not
protrude more than 1/2" into the backbox. Any deeper
penetration will contact the circuit board when the face
plate is installed. If enough pressure is applied, the
circuit board will be bowed and may contact other
components causing erratic behavior.
1. Do not power any other device from the Trigon’s
12 VAC transformer.
2. Do not energize wires until installation is completed.
3. Ground the unit by attaching a separate 12 AWG
ground wire to the ground location on the terminal
block (see wiring diagram Fig. 3) . This ground wire
should go to a grounding rod or grounded metal
conduit.
4. 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. If using
shielded cable, ground the shielding 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.
5. Use 22 AWG wire on Telco / Resident line run
distances of up to 2500 feet. Consult with the factory
for distances greater than 2500 feet. If a substitute
transformer is used, be sure it is rated 12 VAC, 20VA,
U.L class 2 listed. The 12 VAC input power wires
shouldbe 18AWG,600V, insulatedwire. This should
be sufficient for distances up to 200 feet.
6. Isolate the Telco phoneline in and the Resident
phoneline out, from the 12 VAC power wires. This
will prevent 60 Hz hum from occurring on the
phoneline.
7. Use the enclosed wiring diagram (Fig. 3) for wire
connection information. Be sure to hook up the
memory battery.
8. Relays 1 and 2 are dry contact Form C type, rated
for 5AMPS @ 30 VDC/ 250VAC. A 3-wire harness
is included to wire the relay outputs.
9. Energize unit. You should hear one beep followed
by four beeps if unit is new or if the battery was
disconnected during a power failure. The four beeps
mean the unit is initializing memory.

other previous code) is no longer valid. Keep good,
safe record of your new programming code for future
use.
Note:Note:
Note:Note:
Note: Gate Control Mode is achieved by using the
first 2 digits of the program code. If the program code
is changed to “1234” then Gate Control Mode is
achieved by tone dialing “12*” from inside the house.

A. Calling the Resident:
A visitor simply presses the “call” button on the front of
the CastleGate III to alert the resident to their presence.
Theunit thenautomatically ringsthe resident'stelephone.
When the call is received, the resident my grant entry by
dialing “6” or “9” on their telephone. To deny entry, the
resident simply hangs-up their telephone handset.
Residents may let themselves in by using a
programmable 4-digit “keyless” entry code. Up to 50
such codes may be programmed into the CastleGate II.
To avoid issuing keys, codes may be given to gardeners,
pool maintenance personnel, and such. All codes can be
easily voided.
Residents will know when a visitor is requesting entry,
even if they are using their telephone at the time. Atone
will notify them of an incoming call. They then press
the “#” key on their telephone to put the outside call on
hold. When the visitor at the gate has been granted or
denied access, the resident can return to their outside
call by again pressing the “#” key on their telephone.

In the case where you are using your telephone when a
call is initiated at the gate, you will hear a short tone in
your handset every 3 seconds. To see who is at the gate
without interrupting your call, press a ‘#” tone from a
touchtone telephone. The person on the telephone with
you will automatically be put on hold and you will be
transferred to the visitor at the gate. After handling the
gate call, you may switch back to your previous
telephone conversation by pressing “0” or “#”. If you
hangup while someone is on hold or during an incoming
call, the CastleGate II will alert you by ringing your
telephone approximately 3 seconds later.
If you are talking to a visitor at the gate and you receive
an incoming telephone call, you will hear a clicking
sound in your handset. After handling the gate call,
press the hookswitch momentarily to answer incoming
telephone call.
