Indicators, Controls, and Operation
Subsequent First Stage alarms when the panel is already in alarm, cause the following:
• The buzzer sounds steadily
• If signals have been silenced as a result of the silence button or the Auto signal silence timer, signals are
resounded as they were before signal silence, the Signal Silence LED turns off, and the Auto Signal Silence
timer, if configured, is restarted
• If the panel is not already in General Alarm, additional non-disconnected signals programmed to the new input
are activated with the Alert Code (see Indicating (Signal) Circuit Types section).
• If the panel is not already in General Alarm and if the Acknowledge LED is on steady indicating that the Auto
General Alarm timer has been Acknowledged the timer is restarted and the Acknowledge LED is extinguished.
A second stage alarm (general alarm) when the panel is already in alarm causes the following:
• The buzzer sounds steadily
• All non-disconnected signals are activated at the evacuation rate
• If the Signal Silence LED is on, it turns off and the Auto Signal Silence timer, if configured, is restarted
• The Acknowledge LED if on, turns off
Alarm inputs are latching: they remain active until system reset.
Note: If the system is configured for correlations, any second stage / general alarm condition activates all
NACs whether they are correlated or not.
Pre-Signal Operation
To configure the panel for pre-signal, all alarm inputs must be correlated to one NAC circuit that is wired to a
Notification Appliance in the Control Room that is constantly monitored by an Operator. Using the FX-2000N
Configurator, "Subsequent Alarm" in "Common System Status" must be correlated to turn on the Remaining NAC
circuits in the system. To confirm the alarm (i.e. subsequent alarm) the operator can press the "General Alarm"
button on the panel or activate a Manual Station in the Control Room.
Note: Pre-Signal is not permitted to be used in Canada, unless approved by the AHJ.
