Operating Instructions Operation
42 MS-2/MS-4 PN 51512:E 01/18/05
4.4.1 Fire Alarm Response
The control panel will, upon detection of an alarm condition, cause the following:
• Latch the alarm condition - requires panel reset to clear alarm condition
• Blink the Zone Alarm LED one second On and one second Off
• Turn on remote annunciator alarm LED and piezo sounder
• Turn the Notification Appliance Circuit(s) on
• Turn the FACP piezo sounder on steady
• Turn on the alarm relay
• Start the Silence Inhibit, Auto-silence and Trouble Reminder functions if enabled
4.4.2 Fire Alarm Restoral
The control panel returns to normal after all alarms have been cleared and a system
reset button has been pressed (pull stations have been reset, smoke detectors have reset
and no smoke is present, waterflow has stopped). The control panel will perform the
following upon restoral of all active alarms:
• Turn off the FACP Zone Alarm LED
• Turn off remote annunciator alarm LED and piezo sounder
• Turn off the Notification Appliance Circuit(s)
• Turn off the FACP piezo sounder
• Turn off the alarm relay
• I3 smoke detectors will be polled for maintenance and freeze conditions on initial
entry into Normal mode. Thereafter, each device will be polled every hour for
freeze and every four hours for maintenance conditions
4.4.3 System Supervisory Condition Response
Zones can be programmed for supervisory in applications where a waterflow sensing
device has been employed and a sprinkler tamper switch is to be monitored. An I
3
detector in a ‘freeze’ condition (detected abnormally low ambient temperature) will
also generate a supervisory condition on its alarm zone (refer to the I
3
specification
sheet for temperature threshold). Any supervisory condition will cause the control
panel to perform the following functions:
• Blink the FACP Zone Supervisory LED ½ second On and ½ second Off
• Pulse the piezo sounder ½ second On and ½ second Off
• Turn on the supervisory relay (MS-4 only)
4.4.4 System Supervisory Restoral Response
When the supervisory condition has been cleared, the control panel will perform the
following:
• Turn off the FACP Zone Supervisory LED
• Turn off the piezo sounder
• Turn off the supervisory relay (MS-4 only)
