Step 4 Check whether the re alarm control panel displays any alarm. If an alarm is
displayed, clear the alarm before performing follow-up operations.
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 re alarm.
● A smoke detector loop alarm is triggered, and the loop 1 re alarm indicator on the
extinguishant control panel is steady on. The 
re alarm bell rings.
● Do not clear the alarm and proceed to the alarm simulation for the smoke detector.

Step 6 Heat the heat detector using a heat gun until the heat detector indicator changes
from blinking once every six seconds to steady on to trigger a heat detector FIRE
RELAY alarm.
A heat detector loop alarm is triggered, and the loop 2 re alarm indicator on the
extinguishant control panel is steady on. The horn strobe is triggered, and the warning sign
blinks. The Release Imminent indicator on the extinguishant control panel turns on, and
the release countdown starts. When the countdown ends, the ejector of the electrical
actuator pops up.
