900 MHz WIRELESS DUAL BAND REPEATER
DoorKing Part Number
2332-080
Installation
Note: DoorKing offers a 900 MHz Wireless Test Range Kit (P/N XXXX-XXX) to allow easy testing of the wireless signal between 2 devices at
chosen locations BEFORE installing the devices. The self-powered test kit measures the 900 MHz wireless signal between 2 devices in ANY
chosen locations. Ensuring a good signal can be achieved before installation occurs.
The 900 MHz wireless dual band repeater (DBR) extends the wireless communication range between an access control system (900 MHz wireless
baseboard) and 900 MHz wireless tracker expansion board. It gets installed between the wireless devices that are too far or obstructed from each
other to reliably communicate with each other. It will receive a signal sent to it and repeat that signal to the next wireless device. Up to 2 DBRs can
be used in the same communication line of a tracker expansion board. The signal range of a DBR is Up to 1000 ft direct-line-of-sight with no
signal interference. See “900 MHz Wireless Baseboard Manual” for complete access control system wireless setup information.

IMPORTANT:
Install the DBR
so the antenna is in a
location that is NOT
surrounded by metal
and is in free air as
high as possible above
the ground. Minimum
15 ft above ground
recommended.
1/2” thick wall
PVC conduit
recommended
(not supplied).
Metal conduit
may interfere
with wireless
signal.
Base side communicates with the
wireless Baseboard of the 1830
series. The CH and NET ID of the
Base side MUST match the CH and
Net ID of the Baseboard.
DO NOT set Base side the same as
the Remote side.
TIP: It is best to keep the CHs at least 3 numbers away from each other if
possible for signal separation. This helps eliminate interference between
base side and remote side.
Remote side communicates
with the wireless Tracker
board. The CH and NET ID of
the Remote side MUST match
the CH and Net ID of the
Tracker board.
DO NOT set Remote side the
same as the Base side.

RF STRENGTH LEDs (Base/Remote)
Off in normal operation. When signal is
displayed (press base/remote SIG button)
it is either green-good, yellow-weak or
red-NO. When signal is displayed, LED
blinks until signal is received, once
received, it stays lit.
Note: Signal display is terminated if either
Base or Remote PROGRAM button is
pressed or the number of minutes is
reached as selected by the SIG button.
RF SYNC LEDs (Base/Remote)
Off in normal operation. Blinks green
everytime data is received over the air.
RF LOST LEDs (Base/Remote)
Off in normal operation. Blinks when no air
data is detected after six minutes and stays
lit after NO air data is received for 10
minutes.

Up to 2 Dual Band
Repeaters (DBR) can
be used in a cascade
format to extend
signal distance. The
Base Side of 2nd
DBR MUST match
the CH and NET ID of
the Remote Side
from the 1st DBR
and so on. Make
sure the CH and NET
ID combinations are
UNIQUE for every
DBR in the cascade.
