5.5 Single Stage Operation

In a single stage system, all alarm inputs are treated in a similar manner. Alarm inputs include

any of the following:

• Non-verified alarm

• Verified alarm

• Waterflow alarm

• Sprinkler alarm

Any of the above alarm inputs activating when the panel is not already in alarm cause the

following:

• The buzzer sounds steady.

• Cancels active fire drill.

• Common Alarm LED turns ON.

• Common Alarm relay activates if Aux disconnect is not active.

• The Auto Signal Silence timer activates (if configured).

• The Signal Silence Inhibit timer activates (if configured).

• If Aux disconnect is not active, activates all non-disconnected indicating circuits

programmed to the input.

• Activates non-disconnected strobes associated with the input.

• Activates non-disconnected signals associated with the input at the evacuation rate.

Subsequent alarms when the panel is already in alarm, cause the following:

• The alert buzzer sounds steady.

• Resounds silenced signals, turns off the Signal Silence LED, and restarts the Auto

Signal Silence timer (if configured).

• Activates continuously any additional non-disconnected strobes associated with the

input.

• Activates at the evacuation rate any additional non-disconnected signals associated

with the new input.

5.6 Two-Stage Operation

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

• Water-flow alarm

Second stage inputs include the following:

• Alarms on the general alarm inputs.

• Activation of the General Alarm button.

• Expiration of the Auto General Alarm timer.

Any of the above alarm inputs activating when the panel is not already in alarm cause the
