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. Ademco 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 "Lowbat" message enter:
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.
Changing the Lynx Plus Series System Battery
In the event of an AC power loss, the Lynx Plus Series is powered by a rechargeable, nickel-metal
hydride battery pack. The battery pack should be replaced when a "Lowbat" message with no zone
number is displayed. Following battery pack replacement, rechargeable batteries may take up to 48
hours to charge. The "Low Bat" message may be displayed after one minute, however it should clear
within 4 hours or by entering Test Mode.
NOTE: The battery pack (P/N LYNXRCHKIT-SC, LYNXRCHKIT-HC or LYNXRCHKIT-SHA) should be
changed every four years and must be replaced by a qualified service technician.
