Acknowledging Alarms
Your system can be configured to handle multiple alarms. Each alarm can be
configured to automatically call up video and initiate an auxiliary, such as an audible
alarm. In addition, whenever an alarm is triggered, the keyboard beeps, signaling an
active alarm.
To acknowledge an active alarm, press the
Ack
button. Continue to press the
Ack
button until all active alarms have been cleared.
Refer to the appropriate operating instructions to determine the number of alarms
your system can handle, as well as to determine how many alarms can be active at one
time.

Auxiliary Control
An auxiliary is a device, such as a light, audible alarm, or door lock, that can be
controlled using the matrix keyboard. Auxiliaries may also be initiated automatically
in response to an alarm. The
Auxiliary On and Auxiliary Off buttons are used to
control the operation of both momentary and latched auxiliaries.
A momentary auxiliary remains active as long as its control button is pressed. An
example of a momentary auxiliary is a door that remains unlocked as long as the
Auxiliary On
button is pressed. When the button is released, the door returns to its
locked state.
A latched auxiliary remains active until it is deactivated using the appropriate off
switch. An example of latched auxiliary is a light. When the
Auxiliary On
button is
pressed, the light is turned on. When the
Auxiliary Off
button is pressed, the light is
turned off.
