Active Event Operation of the Control Panel
2.13 Active Event
2.13.1 How the Control Panel Indicates an Active Fire Control
Point
A point with a Type ID of FIRE CONTROL is used for air handler shutdown, intended to override nor-
mal operating automatic functions.
Activation of a
FIRE CONTROL point causes the control panel to do the following:
• Initiates the monitor module Control-by-Event
• Send a message to the panel display, History buffer, installed printer and annunciators
• Does NOT light an indicator at the control panel
•Displays ACTIVE in the upper left corner of the LCD, as well as a
FIRE CONTROL Type Code
and other information specific to the device
2.13.2 How the Control Panel Indicates an Active Non-fire Point
A point with a Type ID of NON-FIRE is used for energy management or other non-fire situations.
NON-FIRE point operation does not affect control panel operation, nor does it display a message at
the panel LCD. Activation of a
NON-FIRE point activates CBE—but does not cause any indication
on the control panel. For example, you can program a
NON-FIRE point to turn lights in a zone to a
lower setting when activated. In this case, when the point activates the control panel activates the
point’s CBE to turn the lights down without any audio or visual indication on the control panel.
2.14 Operation of Special System Timers, Presignal, and PAS
2.14.1 System (Panel) Timers
There are user-programmable time delays for four specific functions: Alarm Verification, AC Fail,
Silence Inhibit, and Auto Silence. Refer to this panel’s programming manual for instructions on
viewing or modifying these values. (They may be viewed only in programming mode.)
Alarm Verification Timer (VERIFY TIME)
A timer that directs the control panel to ignore a fire alarm for a smoke detector, programmed for
Alarm Verification, while the Alarm Verification Timer is counting. The timer value can be set
from 0-60 seconds, and may not exceed 30 seconds for ULC installations. Table 2.3 contains a
summary of how the Alarm Verification Timer works.
AC Fail Delay Timer
This timer delays the time from the start of AC failure to when the trouble is reported. The timer
value may be set to none, or from 1-12 hours. A value of “none” will cause immediate notification.
The onboard trouble relay and municipal box output will activate when the countdown is complete.
Note that this panel notifies the central station communicator as soon as AC failure occurs, and the
central station communicator follows its own programmed schedule for reporting the failure.
If this event occurs The control panel does this
A second fire alarm occurs while the
Alarm Verification Timer is counting
Ignores the Alarm Verification Timer and alarms are
reported by the panel for both detectors.
The Alarm Verification Timer elapses and
a fire alarm still exists
Activates the fire alarm
The Alarm Verification Timer expires and
a fire alarm no longer exists
The control panel returns to normal operation and
increments the verification counter
