In a Two Stage System Alarm inputs are either First Stage (Alert) inputs or Second Stage (General Alarm) inputs. First
Stage inputs include inputs from the following types of circuits: Non-Verified Alarm, Verified Alarm, Sprinkler Alarm,
and Water-flow Alarm. Second Stage inputs include Alarms on Gen eral Alarm Circuits, activation of the Gen eral Alarm
button, or ex piration o f the Auto G ene ral A larm Tim er. Any o f 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 Indicator turns on
The Common Alarm Relay activates if Aux Disconnect is not active
The Auto Signal Silence Timer, if configured, starts
The Signal Silence Inhibit Timer, if configured, starts
All Non-Disconnected Relays programmed to the input are activated provided that Aux Disconnect is not active
If the alarm is a Second Stage alarm all non-Disconnected Strobe Circuits are activated continuously, all non-
Disconnected Signal Circuits are activated at the evacuation rate, and the General Alarm indicator is turned on. If the
alarm is a First Stage alarm, non-Disconnected Strobe Circuits programmed to that circu it are activated continuously,
non-Disconnected Signal C ircu its prog ram me d to tha t circu it are a ctiva ted w ith the Alert C ode (s ee Indic ating C ircuit
Types, in following section) and the Auto Genera l A la rm Timer, if configured, starts, and the Acknowledge Indicator
starts flashing. 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 Indicator is turned 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 Circuit Types, in following section).
If the Panel is not already in General Alarm and if the Acknowledge Indicator 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 is sounded steady
All non-Disconnected Signals are activated at the evacuation rate
If the Signal Silence Indicator is on, it is turned off and the Auto Signal Silence Timer, if configured, is restarted
The Acknowledge Indicator if on, is turned off
