Step 5 Check whether the extinguishant control panel displays any alarm. If an alarm is displayed,

clear the alarm before performing follow-up operations.

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
