Notes
• During a power failure, the sealed lead acid (SLA) backup battery provides power to the monitoring system
and the power failure alarm. If the backup battery is not functioning, the power failure alarm will not be activated.
• If the backup battery does not provide power to the monitoring system during the power failure alarm test, replace
the battery.
• Use only a 12V 7AHr SLA battery for the standard monitoring and alarm system battery backup.
• Use only a 12V 18AHr SLA battery (quantity 2) for the PC100-Pro integrated full system battery backup.
