900 MHz WIRELESS DUAL BAND REPEATER
DoorKing Part Number
2332-080
Installation
Note: DoorKing offers a 900 MHz Wireless Test Range Kit (P/N 1514-140) 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. ONLY 1 DBR can
be used in the same communication line of a tracker expansion board. The signal range of a DBR is Up to 1500 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 2 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.
