DIP Switch Settings

3.1.1SW1 DIP Switch Settings

3.1.1.1Silence Inhibit

Switch 1, placed in the ON position, selects the Silence Inhibit feature. This feature prevents the silencing or resetting of the NACs (Notification Appliance Circuits) for a period of one minute after initiation of an alarm. Placing switch 1 to the OFF position deselects the Silence Inhibit feature. The factory default setting is switch 1 OFF for no Silence Inhibit.

3.1.1.2 Auto-silence

Switch 2, placed in the ON position, selects the Auto-silence feature. This feature automatically silences all NACs, programmed for silenceable operation, ten minutes after alarm activation. A new activation on another zone will resound the NACs. The factory default setting is switch 2 OFF for no Auto-silence.

3.1.1.3 Temporal Coding

Switch 3, placed in the ON position, selects the Temporal Coding feature. This feature causes the NACs to pulse, ½ second on, ½ second off, ½ second on, ½ second off, ½ second on, 1½ seconds off, continually repeating this pattern while activated. The factory default setting is switch 3 OFF for no Temporal Coding, which will cause the NACs to sound a steady signal when activated.

Note that Temporal Coding is disabled if Strobe Synchronization is enabled.

3.1.1.4 Selective Silence

Switch 4, placed in the ON position, selects the Selective Silence feature. This feature allows the use of various manufacturer’s horn strobe mute protocols. When Selective Silence is enabled and the Synchronization feature is selected (refer to "Strobe Synchronization" on page 37), pressing the Silence button will turn off all silenceable audible devices while leaving on the visual devices, such as strobes. The factory default setting is switch 4 OFF for no Selective Silence.

Note: Enabling Selective Silence but not Synchronization will cause audible and visual devices to be turned off when the Silence button is pressed.

3.1.1.5 Trouble Reminder

Switch 5, placed in the ON position, selects the Trouble Reminder feature. This feature causes the FACP piezo to sound every 15 seconds for alarms and every two minutes for troubles after the alarms or troubles have been silenced. In addition, the piezo will resound 24 hours after a trouble has been silenced but not cleared. The factory default setting is switch 5 OFF for Trouble Reminder disabled.

3.1.1.6 AC Trouble Delay

Switch 6, placed in the ON position, selects the AC Trouble Delay feature. This feature allows the FACP to delay trouble activation for six hours following an AC loss or brownout condition. The factory default setting is switch 6 OFF for no AC Trouble Delay.

3.1.1.7 Autoresettable Supervisory

Switch 7, placed in the ON position, selects the Autoresettable Supervisory feature. This feature causes the IDCs (Initiating Device Circuits), programmed as supervisory circuits, to automatically reset (nonlatching) after the alarm condition has been cleared. The factory default setting is switch 7 OFF for no Autoresettable Supervisory.

3.1.1.8 IDC Combination Circuit

Switch 8, placed in the ON position, sets IDC #1 on the MS-2 or IDC #2 on the MS-4 as a combination circuit. A combination zone can be used for monitoring supervisory devices such as valve tamper switches and alarm devices such as waterflow switches. Supervisory conditions, which latch via software, can be silenced by pressing the Acknowledge and then Silence buttons. The factory default setting is switch 8 OFF for no Combination circuit.
