Alarm types and sounds
An alarm may occur for several different reasons. For example:
 A zone is triggered when the system is set (intruder alarm).
 The lid of the control unit or other device has been opened without the
installer being logged in (tamper alarm).
 After entering the premises, a user has failed to unset the system in
sufficient time.
 A fire detector is activated.
 A Hold-Up Alarm (HUA) device is activated.
 The mains supply has failed.
 There is a failure of a communications link from the control unit.
When an alarm occurs, the control unit normally activates internal sounders
and, depending on severity, external siren/strobe units. Table 1 shows the
default response for each type of alarm.
After an alarm, you will need to silence the sounders, acknowledge the
alarm and reset the system (see "Silencing, acknowledging and resetting
alarms" on page 26).
