	- Alarm Verification Feature (AVF) Module to reduce incidence of false alarms caused by transient activating conditions.
 
	- In a detection zone upgraded with AVF, detector activation will be re-set. If more detections appear within the verification period, the normal general alarm sequence will then be set-off
 
	- The LED doubles as voltage readout when "lamp test" is pressed
