Alarm Power Supply
Intruder alarm systems need power supply to operate, regardless if they are hardwired or wireless. An Intrusion alarm power supply, also known as an alarm transformer, plugs into an electrical outlet in the home and gives an alarm system the power it needs to operate efficiently.ATSS alarms require 220-240 V AC/50 Hz Power supply.
Back-up Battery
Battery Backup is always recommended for intruder alarm system. If a home ever loses power, for any reason, the back-up battery will kick in and will power the alarm until the electricity is restored. ATSS alarms require 12 V 7 Ah Battery.
