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.
