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.
NO TE
● A smoke detector loop alarm is triggered, and the loop 1 fire alarm indicator on the
