turns OFF, and the Auto Signal Silence timer, if configured, is restarted. For Canadian
installations, disable Auto Signal Silence.
• 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 section 11.8 Output
Types on page 53).
• If the panel is not already in General Alarm and if the AUTOMATIC ALARM SIGNAL CANCEL LED is
ON steady indicating that the Auto General Alarm timer has been acknowledged the timer is restarted
and the AUTOMATIC ALARM SIGNAL CANCEL 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. For Canadian installations, disable Auto Signal Silence.
• The AUTOMATIC ALARM SIGNAL CANCEL LED if ON, turns OFF.
Alarm inputs are latching, they remain active until system reset.
11.5 Positive Alarm Sequence
In a Positive Alarm Sequence (PAS) system, only smoke detectors can be dedicated as PAS
inputs. PAS Inputs can only be from the following types of circuits: non-verified alarm and
verified alarm. Any of these alarm inputs occurring when the panel is not already in alarm
cause the following:
• The buzzer sounds steadily.
• If fire drill is active, it is cancelled.
• The Common Alarm LED turns ON
• The individual zone LED (if programmed) turns ON.
• The Common Alarm relay does not activate.
• The PAS timer starts for 15 seconds.
• All outputs programmed to the input are not activated.
When the PAS alarm has been acknowledged within 15 seconds, the following sequence
occurs:
• The buzzer is silenced.
• The Common Alarm LED stays ON.
• The individual zone LED (if programmed) stays ON.
• The PAS timer starts for 180 seconds (3 minutes). This is the time allotted to reset the
system and avoid any true alarm sequence.
When the PAS alarm has been acknowledged and the system reset (and there are no new
alarms), within the given time limits, the following occurs:
• The buzzer stays silenced.
• The Common Alarm LED turns OFF.
Note: All circuits with process type designated as “signal” are automatically correlated
to the “fire drill” and “general alarm” status.
