System Alarm

Local alarm
Local alarms occur when an area is occupied (disarmed). For example, zones with 24-hour security have been
activated such as a fire door being opened. The circumstances that caused a local alarm need to be checked and
rectified by someone on site. The alarm does not need to be reported to a central station.

Alarm
An alarm occurs when:
• The area is armed and one of its zones has been activated. For example, a door lock has been forced
open causing a siren to sound.
• The area is disarmed and a 24-hour zone was activated. For example, a hold-up button is activated or a
tamper switch is open.
• The exact type of alarm (siren, flashing light, and so forth) depends on how the system has been
programmed.
• The area LEDs on the RAS indicate the areas in alarm.

System alarm
Alliance defines a system alarm as the state of a security system when an Alliance system device (control
panel, RAS, or DGP) is tampered, stops communicating, or detects a fault condition such as an AC fail or a low
battery.
Examples:
• Alarm equipment interfered with or covers removed (DGP tamper)
• Communications cabling interfered with – cut or shorted (DGP or RAS fail)
• Connections to siren speakers interfered with – cut or shorted (siren fail)
• Telephone line connection lost due to disconnection, short, or other failure (line fault)
• Panel failed to report a pending event to the central station (report failed FTC)
• Power supply interrupted and/or overload and battery problems (AC fail, fuse fail, low battery)
The exact type of alarm depends on how the system has been programmed.
