Security Alarm Event
(Not Suitable for Canadian Applications)
How the Control Panel Indicates a Security Alarm
The system indicates a Security alarm when a monitor module point programmed with a security
Type Code activates. The panel will react differently depending on whether or not there are higher
priority unacknowledged events.
When no higher priority unacknowledged events exist, the control panel:
•Produces a warbling audible tone (if the piezo is enabled)
•Activates the Security relay (TB1) if it has been selected for security
•Flashes the
SECURITY LED (blue)
•Displays a Type Code that indicates the type of security alarm being generated
•Displays
SECURITY in the upper left corner of the panel display along with information
specific to the device
•Sends a Security message to the History buffer, installed printers and annunciators
When an unacknowledged event with a higher priority exists, the control panel retains the
indications of the higher priority event (the message, lit LED, audible tone, etc.) while activating
the Security relay if it is selected for security, flashing the
SECURITY LED, and sending a Security
message to the history buffer, installed printer and annunciators. If there are silenced alarms (the
SIGNALS SILENCED LED is lighted), a Security alarm will resound the panel sounder.
A Typical security message that appears on the panel display:

How to Respond to a Security Alarm
A latching Security Type Code latches the control panel in a security alarm. To return the control
panel to normal operation, it is necessary to correct what is causing the security condition, as
indicated in the numbered steps below, then reset the control panel.
If the control panel indicates a security alarm, take the following action:
1. Press the ACKNOWLEDGE soft key to silence the panel sounder and switch the
SECURITY LED
from flashing to steady—regardless of the number of troubles, alarms, supervisory, and
security signals. The control panel sends a Security message to the History buffer and installed
printers.
2. Press the MORE INFORMATION soft key to display the MORE INFORMATION screen and
view additional information on the device and possibly preprogrammed text for recommended
