This control panel has alarm delay function of max. 60 seconds for the fire signal from detector.
Summary of delay operation is as follows. (The time is from all fire signal input time.)
About 10 seconds after detector operates, a reset pulse is output and detector is forced to reset
automatically. About 20 seconds later, the control panel becomes fire signal count mode and when
detector operates again, the control panel outputs fire alarm. Fire signal count mode continues for
about 60 seconds and the panel returns to monitoring condition unless a detector actuates by then.
There are two ways of delay time and fire alarm is output about 20 seconds after heat detector
operates and about 20~60 seconds after smoke detector operates.
When manual alarm station operates, fire alarm is output immediately.
