Presignal
Presignal is used to delay output activation (control modules and NACs) while allowing for visual
verification by a person. Once a detector or monitor module triggers an alarm, the panel sounder
sounds immediately, but the Notification Appliance Circuits are not activated for 15 seconds. During
this time, if the

key is pressed, the panel sounder is silenced and the notification
appliances will not activate for up to three minutes. After three minutes, the NACs will activate if the
source of the alarm is not cleared. This does not affect monitor modules programmed as waterflow or
supervisory.
Note:
Presignal operation requires the approval of the local Authority Having Jurisdiction.
