SYSTEM FUNCTIONS
Maintaining your system
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.
The components of your security system are designed to be as maintenance-free as possible. To make
sure that your system is in working condition, do the following:
1. Test your system weekly.
2. Test your system after any alarm occurs (see the Testing the System section).
Low Battery Conditions in Wireless Sensors
Each wireless sensor in your system has a 9-volt or 3-volt battery. The system detects low battery
conditions in wireless sensors, including smoke detectors, personal emergency transmitter, and the
portable wireless keypad, and displays a “Low Bat” message, on the master keypad, which also beeps. A
low battery in a wireless keypad is detected as soon as one of its keys is pressed, and the master keypad
(e.g. 5827) will display “00”. In addition, a wireless smoke detector with a low battery also emits a
"chirp" sound approximately once every 20–30 seconds, identifying itself as the smoke detector with the
weak battery.
NOTE: A low battery message means that battery replacement in the indicated sensor(s) is due within 30
days. In the meantime, a sensor with a low battery is still operational.
To silence Low Battery Warning Tones at the Keypad: Press the OFF key.
The low battery message display will remain on as a reminder. When you replace the weak battery
with a fresh one, the sensor will send a "good battery" signal to the control when the sensor is activated
(opening/closing of door, window, etc.).
To clear the “Low Bat” message enter:
+ OFF key.
Your user code
When replacing batteries, use only those recommended by your installer.
Alkaline batteries provide a minimum of 1 year of operation, and in most units and applications, provide 2–
4 years of service. 3-volt lithium batteries may provide from 4-7 years of operation. Actual battery life will
depend on the environment in which the sensor is used, the number of signals that the transmitter in the
sensor has had to send, and the specific type of sensor. Factors such as humidity, high or low
temperatures, and large swings in temperature may all lead to the reduction of actual battery life in an
installation.
