Positions of automatic and manual indicators
In the AUTO state, the AUTO indicator lights up. In the MANUAL state, the MANUAL indicator
lights up.
If the status is MANUAL, the fire alarm control panel generates no electromagnetic valve driving
voltage when fire alarms from the smoke detector and heat detector are triggered.
Step 5
Blow smoke towards the smoke detector using a smoke pistol until the smoke detector
indicator changes from blinking once every 6s to steady on to trigger a smoke detector fire
alarm.
On the fire alarm control panel, the indicator of a first triggered fire alarm changes from off to
blinking, and the indicator of the second triggered alarm changes from off to steady on if two fire
alarms are triggered in turn.
If no smoke pistol is available, you can also short-circuit the
26
and
GND
terminals on the control
circuit board using a conducting wire to trigger a smoke detector fire alarm. After short-circuiting
the
26
and
GND
terminals, remove the conducting wire if an alarm has been triggered.
