Operation of the Control Panel Active Supervisory Signal Mode of Operation
3.5.2 How to Respond to a Security Alarm
A Security Type Code latches the control panel. To return the control panel to normal operation,
you must correct the condition causing the security condition, then reset the control panel. If the
control panel indicates a security alarm, take the following action:
1. Press the ACKNOWLEDGE/SCROLL display 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 remote
annunciators, history buffer, installed printers, and CRT-2s.
2. Correct the condition that activated the Security point.
3. When you finish correcting the Security condition, press the SYSTEM RESET key to return the
control panel to normal operation (indicated by the “System Normal” message). The control
panel sends a “System Normal” message to the LCD display, remote annunciators, history
buffer, installed printers, and CRT-2s.
3.5.3 Interpreting Security Type Codes
The Type Code that displays in the security alarm message indicates the type of security alarm
being generated by the monitor module that initiates the alarm. For example, a monitor module
with a Type Code of
AREA MONITOR indicates an intruder in a protected premises area. The table
below lists the Type Codes that can appear in a security alarm message.
3.6 Active Supervisory Signal Mode of Operation
3.6.1 How the Control Panel Indicates an Active Supervisory
The system goes into Supervisory mode when a monitor module point programmed with a
Supervisory type code activates. When a Supervisory point activates, the control panel does the
following:
• Produces a warbling audible tone
• Turns on the Supervisory relay (TB5)
• Flashes the SUPERVISORY LED (yellow)
• Displays one of the Type Codes listed in Table 3.3.
•Displays ACTIVE in the status banner on the control panel, along with information specific to
the device
NOTE: If a fire alarm exists, and there are silenced alarms (the SIGNALS SILENCED LED is
lighted), a Security alarm will resound the panel sounder.
