Channel Selection: Press the Channel button to set
intercom to one of four secure channels or the paging
channel. The default channel for the intercom is the
Paging channel where all four channel lights will flash
in sequence. An intercom on a channel can only hear
an intercom on the same channel or on the Paging
channel.
Command Gate: A gate can be opened with a call
from an intercom. When an intercom has been
activated by another intercom, the talk button can be
pressed to secure a channel to the gate. To allow
access from the gate, press and release the Remote
button to open the gate.
The gate can also be opened without a call from an
intercom. Press and hold the Remote button and an
initial beep will be heard. Continue to hold until a
second beep is heard, then release.
If pressing the Remote button did not open the gate,
a siren noise will be heard. No siren noise indicates a
successful signal transmission.
Switch Settings: Switch #1 and #2 determine which
GCU the intercom will activate. Default Identity is #1
(both Dipswitches DOWN).
SW1: GCU Mode (see chart
below for setting)
SW2: GCU Mode (see chart
below for setting)
SW3: Conference Mode (UP is
Conference Mode, DOWN is
Secure Mode)
SW4: Not used. Leave in default position (DOWN).
Default for all switches is DOWN.
NOTE: The following step applies only if more than
one GCU is being used.
Up to four GCUs can be used. Each GCU will have a
different Identity. Set the Identity of the GCU by
changing the Dipswitches as shown in the chart
below.
Operation & Features
Talk Button
Talk Button: To talk, hold
down the Talk button. All
intercoms in the network that
are on the same channel will
receive the signal. Release the Talk
button when done talking and within 10-15 seconds
press and hold the Talk button of a different intercom
to make a secure channel between the two. Once the
channel is made the other intercoms in the network
cannot hear the conversation.
Volume: Hold down the Talk button and press the
Channel button repeatedly to cycle through the
volume levels.
Battery: When batteries are low intercom will emit
two beeps every ten minutes. Replace with C
batteries (not provided).
NOTE: To prevent damage to the circuit DO NOT use
C size Lithium batteries.
The Intercom allows multiple simultaneous
conversations, using a 900 Mhz secure digital radio
link. The intercoms form an exclusive network and
respond only to other intercoms in the network.

Troubleshooting
Intercom does not function.
It is normal for LEDs to go out if intercom has been
inactive for 5 minutes. The LEDs should light after a
button is pressed or a signal is received.
Check batteries in Intercom.
Ensure intercom is connected to a network.
See Program.
Ensure that intercoms are on the same channel. See
Operation & Features.
Intercom is not getting expected transmission
range.
Keep Intercom away from trees, metal objects and
electrical wiring.
Intercom does not activate the gate.
If there is no communication between the intercom
and a primary device (like the GAPLM), the Channel
Light on the intercom will light solid for 10 seconds
without any additional audio warnings.
Relocate the intercom or primary device or use
repeaters to complete radio link.
Intercom emits a siren noise after Remote button
is activated.
Verify the GCU is within range of the intercom or
intercom systems. Repeaters may be required to
allow intercoms to communicate with the GCU.
Replace batteries in the GCU.
Intercom beeps every ten minutes.
The battery is low in the intercom. Replace with
C batteries.
NOTE: To prevent damage to the circuit DO NOT use
C size Lithium batteries.
Need to clear intercom’s memory.
Press and hold both buttons. Two beeps will be heard
and the channel lights will begin to cycle. Continue to
hold until a third beep is heard (about 15 seconds).
Ensure other intercoms are not activated during this
time. Intercoms in the network that are on will signal
during the clearing process. Once memory is clear
the intercom can be programmed to a new network.
Static and feedback is heard in intercom.
The intercoms are too close to each other. A cordless
phone, cell phone, or other radio devices can also
cause static.
