Switch Functions in Normal Mode

SECTION 4

Operating Instructions

 

The MS-2 and MS-4 have two modes of operation which are Normal and Walktest

 

modes. Upon initial power-up, the system will be in Normal Mode. This section

 

discusses operation of the control panel in the Normal Mode.

4.1 Switch Functions in Normal Mode

4.1.1 ACK - Acknowledge

The Acknowledge button, which is located on the FACP membrane switch panel, silences the system piezo sounder and changes all flashing system LEDs to on steady. Pressing the Acknowledge button will have no effect on the Notification Appliance Circuits. To activate, press and hold the Acknowledge button for a minimum of one second.

4.1.2 Silence

Pressing the Silence button, which is located on the FACP membrane switch panel, silences the system piezo sounder, turns off the silenceable Notification Appliance Circuits and turns on the Alarm Silence LED. The Silence button will be ignored for nonsilenceable waterflows and NACs. Upon the occurrence of a subsequent event (alarm or trouble), Silence is overridden and the control panel will respond to the new event. To activate, press the Silence button for a minimum of one second.

Note: If Silence Inhibit has been enabled, NACs cannot be silenced for one minute following initiation of an alarm.

4.1.3 Zone Enable/Disable

To disable a zone, press the corresponding Zone Enable/Disable button. The Zone Disable and system Trouble LEDs will blink, as well as the Trouble LED for the disabled zone. To enable the zone, press the Zone Enable/Disable button a second time.

4.1.4 Reset/(Lamp Test)

The system Reset button, which is located on the FACP membrane switch panel, resets the system and any smoke detectors. Each press of the Reset button will cause the following:

Clear all status LEDs

Turn off the Notification Appliance Circuits

Reset all zones by temporarily removing power

Silence the onboard piezo sounder

Restore all system relays to normal

Temporarily remove power from the resettable power output

Note: if Silence Inhibit is active, a panel reset cannot occur for one minute.

Any alarm, supervisory or trouble condition that exists after a system reset will resound the system, reactivating appropriate system activity. Any zones that were disabled before the reset will be disabled after the reset.

Lamp Test - When the Reset button is pressed and then released, the FACP will perform a Lamp Test. All panel LEDs will be turned on and the piezo will sound for approximately two seconds.
