Step 6 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.
If no smoke pistol is available, you can also short-circuit ZONE1+ and ZONE1− terminals on the
extinguishant control panel using a 470-ohm resistor delivered with the extinguishant control panel to
simulate and trigger a smoke detector FIRE RELAY alarm. After short-circuiting the ZONE1+ and
ZONE1− terminals, remove the resistor if an alarm has been triggered.

A smoke detector loop alarm is triggered, and the loop 1 fire alarm indicator on the extinguishant
control panel is steady on. The fire alarm bell rings.
Do not clear the alarm and proceed to the alarm simulation for the smoke detector.
