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.
(1) Fire indicator ····················· Turns on (red), when a fire breaks out.
(2) AC power indicator ············· Normally turning on (blue) and indicates AC power is
being supplied to control panel. If AC power indicator is turning
off, this means either power failure or fuse (F1

meltdown.
(3) Circuit voltage indicator ······ Indicates power-on condition of control panel circuit voltage.
When circuit voltage becomes lower than about 20.4V, the light
turns off.
(4) Switch operation indicator ··· If any one of switches is not at normal position, the light (red)
flickers. (Operation of dip switch in the control panel does not
make the light flicker.)
(5) Telephone indicator ············· When a handset plug is inserted to a telephone jack of manual
alarm station or annunciator panel, the telephone light turns on
(red).
(6) Maintenance indicator········· When maintenance switch in the control panel is pressed to
maintenance side, the light flickers (red).
(7) Zone alarm bell silence indicator --
(a) when zone alarm bell silence switch is pressed at fire, zone
alarm bells silences.
(b) when maintenance switch is pressed to maintenance side, the
light flickers.
(8) Alarm delay indicator ·········· When fire signal is received, when at fire test or when to
measure delay time, this alarm delay indicator turns on (red).
The light turns off about 60 seconds later when no fire alarm is
output.
When general alarm delay switch (S29) in the control panel is
pressed to OFF side, alarm delay indicator flickers.
(The light does not flicker by operation of individual alarm delay
OFF switch.)
