MAINTAINING YOUR SYSTEM
Silencing Low
Battery Warning
Tones at the
Keypad
The keypad’s warning tones can be silenced by performing an OFF sequence (code plus OFF
key), but the keypad's low battery message display will remain on as a reminder that you have
a low battery condition in one or more of your sensors. When you replace the weak battery
with a fresh one, the sensor will send a "good battery" signal to the control as soon as the
sensor is activated (opening/closing of door, window, etc.), causing the low battery display to
turn off. If the sensor is not activated, the display will automatically clear within approximately 1
hour.
Routine Care Treat the components of your security system as you would any other electrical equipment.
Do not slam sensor-protected doors or windows.
Keep dust from accumulating on the keypad and all protective sensors, particularly on motion
sensors and smoke detectors.
The keypad and sensors should be cleaned carefully with a dry soft cloth.
Do not spray
water or any other fluid on the units.
Do not paint over smoke detectors or wireless transmitters.
