For systems with an alternate communicator, a 3600 mAh Ni-MH battery is included. If upgrading the battery from 1500 mAh to 3600 mAh, refer to Section [701] Option 7 in panel programming.

  • Battery life is three to five years under typical operating conditions. Battery capacity deteriorates with age and number of change/discharge cycles. Replace the battery every three to five years.
