Recessed Door/Window Sensor Features and Operation
Your Recessed Door/Window Sensor (SW-ATT-RDW) is a fully monitored sensor that
transmits intrusion alarm information to the DLC-100. The detection portion of the device
is imbedded into the door or window frame, while the magnet is installed adjacent to the
detection device.
Replacing the Recessed Door/Window Sensor (SW-ATT-RDW)
Battery
CAUTION: Opening the battery compartment door when the system is armed triggers
the transmission of a tamper alarm to the AT&T Digital Life Central Monitoring Center.
Therefore, in order to prevent a false alarm, please ensure that the system is disarmed
prior to opening the battery compartment door to replace the battery.
To replace batteries in the recessed door/window sensor, remove the transmitter
assembly from the door or window jams (if installed). Use a flathead screwdriver to pop
off the top cap. Carefully remove the transmitter circuit board from its housing. Remove
the bad battery and properly dispose of it (if applicable). Insert the replacement battery.
CAUTION: Pay careful attention to the battery polarity. The positive polarity (+) is the
side nearest the transmitter printed circuit board.
