Dual Stage Alert/Evacuation
This section describes Programming for Dual Stage Alert/Evacuation
operation (for use in Canada only).
An XPC-8 Notification Appliance Circuit module can be configured for
Dual Stage Alert/Evacuation operation. Under this mode of operation each
circuit operates in one of two stages: alert or evacuation. In the alert stage,
the notification appliance circuit pulses at 20 ppm (pulses per minute). In
the evacuation stage, the circuit pulses at 120 ppm. When configured this
way, each notification appliance circuit has two addresses associated with
it. For additional information, refer to the
XP Transponder Technical
Bulletin (LIT-448180)
in the
IFC-1010/2020 Technical Manual.
The first address is the control address. Activating this point (through its
CBE programming) turns the notification appliance circuit on. This point
uses the Software Type ID CON.
The second address is the stage selection address. This point decides what
state an active notification appliance circuit will be in. Activating this
point puts the notification appliance circuit into evacuation mode. If this
point is not activated, the circuit will be in alert mode. This point uses the
Software Type ID FORC.
Note: If an unacknowledged circuit is in Alert mode for more than
five minutes, all activated circuits on the XPC-8 change to the
evacuation pulse rate.
