Operating Procedures - Off-Normal conditions
The following procedures apply to the PRO-2000 default configuration. It is designed to offer maximum security. Your system may be
configured differently.
General Alarm Condition
The General Alarm Sequence is applied to each control OUTPUT which has been configured as a General Alarm output. The General
Alarm On and Off push buttons can be factory configured to use two of the user-defined buttons. The General Alarm sequence
consists of the following stages:
- When permitted (see NFPA 72 1-5.4.10)
Pre-Alert Stage - initiated by an alarm condition. Alarm is annunicated locally but the GA OUTPUT is not energized during this
time.
- When permitted (see NFPA 72 1-5.4.8)
Alert Stage - General Alarm OUTPUT pulses, On/Off, during this time period. At this stage there is a possibility of fire.
Depending on the GA configuration, the alarm may or may not be silenced at this time using the GA OFF push button at the
panel.
Evacuation Stage - The General Alarm OUTPUT activates and can only be stopped at the panel using GA OFF push button.
However, it can be configured to automatically stop
.
Single New Off-Normal Condition
When all systems are normal and a single New Off-Normal alarm condition is detected (PRO-2000 receives a signal from only one
of its monitoring devices), the following events occur:
• The Off-Normal Condition indicators start flashing (rapidly for alarms).
• If configured (and the condition is not a Trouble), a General Alarm activates as described in General Alarm Condition.
• The buzzer starts beeping rapidly if it is an Alarm and slowly for all other conditions.
• The LCD updates. For example, in the case of an alarm:
Alarm #1 of 1 <NEW> HH:MM:SS
Protected Area Name (User defined)
The time field reflects the time the off-normal was detected.
