REPLACING BATTERIES

From time to time, the batteries in the Sensors and other components on your system will need to be
changed. Your Keypad will indicate when a Sensor's batteries need to be replaced; refer to Sensor Low
Battery in Section 5N or Sensor Faults in Section 5E of this manual.
Under normal conditions, the batteries in your system should last up to three years. When batteries need
to be replaced in a component, follow the instructions in this Section of the manual, being sure to note the
proper orientation of the batteries as they are installed. Also, when batteries in one component need to
be replaced, it is suggested that the batteries in all components be replaced at the same time.
The sounder batteries provide for short-term operation in the absence of AC power. After any prolonged
AC power interruption(s), replacement of all sounder batteries may be required.
All of the batteries used in the security system are common size Eveready Alkaline Energizer batteries
available anywhere batteries are sold.
Put your system into Walk Test before changing batteries in the sensors! This prevents false alarm
signals from being transmitted to your central monitoring station. See Section 7F "Walk Testing
your System".
9A - Tips for Buying Batteries
• Your system is designed to work with Eveready Alkaline Energizer Batteries. When replacing
batteries, be sure to buy the same brand and type of batteries. Do not replace the batteries on your
system with any other type. The reliability of your security system depends on its batteries, and "no
name" or generic brand batteries may not provide the best quality and dependability.
• Use fresh batteries. Most batteries have a "best before" date printed on their packaging or on the
batteries themselves. Buy batteries that have a "best before" date of two years or more from your
purchase date.
• When disposing of used batteries, follow the instructions and precautions printed on the batteries.
Many cities and communities have collection sites or services for used household batteries. Contact
your municipal offices for information on the disposal of used batteries.
• If in doubt about the batteries used in your system, or if you have trouble installing them, contact your
installer for assistance.
