To activate an Auxiliary panic alarm from a touchpad:
Press and hold the Auxiliary button(s) for 2 seconds.
Siren Time-out
If the system is not disarmed after an alarm, the sirens will continue to sound
until the time-out period is reached. The time-out period can be programmed only
by your installer or dealer.
Even though reaching the end of the time-out period stops the sirens, if your
system is monitored, the central station will consider the alarm in progress until
the system is manually disarmed.
