Step 6 Heat the heat detector using a heating device until the heat detector indicator changes from
blinking once every 6s to steady on to trigger a heat detector fire alarm.
If no heating device is available, you can also short-circuit the 25 and GND terminals on the control
circuit board using a conducting wire to trigger a heat detector fire alarm. After short-circuiting the 25
and GND terminals, remove the conducting wire if an alarm has been triggered.

After the short-circuiting, a smoke detector alarm is triggered, and the ZONE1 FIRE indicator on the
fire alarm control panel starts blinking red. The fire alarm control panel reports a single fire alarm
and the fire alarm sounder rings.
Do not clear the alarm and proceed to the alarm simulation for the heat detector.
After the heat detector alarm is triggered, the ZONE2 FIRE indicator on the fire alarm control panel
becomes steady on.
The fire alarm control panel reports another fire alarm, the fire alarm horn/strobe is triggered, and
the gas release countdown starts (the countdown period is configurable and set to 30s by default).
