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.

If a monitor is armed for alarm display, the Run, Hold, Next, and Last buttons are

used to control the alarm sequence (Alarm Tour). The following table describes the

how to control the alarm tour.

Button Description

Run

Starts the tour of alarm inputs currently in an abnormal state.

Hold

Pauses the Alarm Tour.

Steps forwards through an Alarm Tour that is on hold

Last

Steps backwards through an Alarm Tour that is on hold.

Ack

Clears the alarm for the video displayed on the alarm monitor.

For information about arming and disarming alarm monitors, refer to Chapter 4,

Utilities and Advanced User Tasks.

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.
