Optional modules let you expand the system to fi t your
specifi c needs. The Wiegand output module lets you add
card readers and/or remote keypads. Our RF module
provides convenient access through gates or doors
with Passport™ transmitters. Plus, the system is now
designed to automatically detect the addition and location
of each new plug-in module, making installation and
programming faster and easier than ever before.
These instructions are for general installation and setup.

CONNECTING TO THE TELCO LINE
The bypass board allows the unit(s) to be disconnected without interrupting
normal telephone operation. If the unit(s) will be used in conjunction with an
alarm system, you must connect the telephone line to the alarm system fi rst.
If the units are not connected in this order, they will not operate properly.
Up to 7 units can share the same phone line. You must program the unit id’s
for each unit wired in the series. See Keypad Programming manual.
The bypass board (located inside the property) allows access to the phone in
case the unit(s) fail.
NOTE: Installation where fi ber optic phone lines are present may require
additional modifi cations from your telephone provider. Contact your provider
for more information.
• When a unit is in use, the bypass switch must be set to the
operate position.
• When a unit is disconnected, the bypass switch must be set to the
bypass position.

Tip
Tip
• To AVOID damaging gas, power or other underground utility
lines, contact underground utility locating companies BEFORE
digging more than 18 inches (46 cm) deep.
• Contact the building inspector’s offi ce in the municipality where
you plan to install the unit for correct grounding materials and
installation procedures.
• Ensure that the system is grounded properly. The units contain
a number of static sensitive components that can be damaged
by static discharge.
• DO NOT ground the units to a pedestal post (gooseneck) if one
is used.
GROUND THE UNIT
Install an earth ground rod no further than 12 feet from the unit and
use a minimum of 12 gauge wire in most cases. The type and length
of earth ground rods vary by region.
NOTE: Keep ground wire as straight as possible.
ALTERNATIVE GROUNDING SOLUTIONS
The unit may be grounded to a metallic or an existing electrical system
within 12' of the unit.
CONNECTING TO A DEDICATED TELCO LINE
Installation where fi ber optic phone lines are present may
require additional modifi cations from your telephone
provider. Contact your provider for more information.
Up to 7 units may be installed. You must program the
unit id’s for each unit wired in the series.
See Keypad Programming manual.

Alternative Grounding Solutions
CONNECTING TO AN INTERNAL PHONE SYSTEM
The units can be wired to any analog trunk in an internal home phone
system.
Installation where fi ber optic phone lines are present may require
additional modifi cations from your telephone provider. Contact your
provider for more information.
Up to 7 units may be installed. You must program the unit id’s for each
unit wired in the series. See Keypad Programming manual.
CONNECTING TO AN NPBI SYSTEM
Up to 7 units may be installed. You must program
the unit id's for each unit wired in the series.
See Keypad Programming manual.
Disconnect power at the fuse box BEFORE proceeding. The unit
MUST be properly grounded and connected in accordance with
national and local electrical codes. NOTE: The unit should be on a
separate fused line of adequate capacity.
• A static discharge can damage circuit boards
• NEVER run telco wires and high voltage wires in the same
conduit. The high voltage may interfere with the telco wires,
possibly causing the system to malfunction.

Wiring
CONNECTING A GATE OPERATOR
Refer to the gate operator manual for proper relay
strike time. Additional opening or exit devices can
be connected to any of the 4 relays.
CONNECTING A MAGLOCK
The maglock can be connected to any of the 4 relays.
FOR AC POWER: Install a Siemens S10K30 MOV (Metal Oxide Varistor)
or equivalent
FOR DC POWER: Install a 1N4005 diode or equivalent.
DO NOT USE THE UNIT’S POWER SUPPLY FOR THE MAGLOCK.
CONNECTING TO A DOOR STRIKE LOCK
The door strike can be connected to any of the 4 relays.
FOR AC POWER: Install a Siemens S10K30 MOV (Metal Oxide Varistor) or equivalent.
FOR DC POWER: Install a 1N4005 diode or equivalent.
DO NOT USE THE UNIT’S POWER SUPPLY FOR THE DOOR STRIKE.
STAND ALONE SYSTEM
The unit can be a stand alone system that allows communication between
the unit and a resident’s phone. Connect a twisted wire (18-24 AWG) from
the RES terminal block on the unit's output board, to the resident's phone.
Up to 7 units can share the same phone line. You must program the unit id’s
for each unit wired in the series. See Keypad Programming manual.
Only disable the Telco mode of the unit farthest away from the house. See
“Disable Telco Mode” in the Keypad Programming manual.
NOTE: Ringer Equivalence Number (REN) of “5” maximum.
