FUNCTIONAL TESTING (GENERAL)
NOTE: Before performing any functional testing make
sure the Flame Guardian™ is disconnected to
prevent unwanted discharge. See Wiring
Diagram.
To perform any functional test, the following instruc-
tions should be followed.
1. Ensure that the Flame Guardian™ module(s) is/are
not connected to a power source.
2. Perform the desired Functional Test. Sound alarm
will go off.
3. Check fire zone.
4. Press the SIGNAL SILENCE button on the
Guardian™ Panel to suppress alarm.
5. Press the SYSTEM RESET button.
To proceed with testing:
• Restart procedure.
If testing has been completed:
• Reconnect the Flame Guardian™ module(s).
• Make sure the panel is in RUN mode.
FUNCTIONAL TEST (FLAME
GUARDIAN™)
A functional test can be done in two ways:
• By simulation
• True functional test
Simulation
1. Two heat resistant wires are connected to an inter-
nal metal spiral activator in the Flame Guardian™.
The spiral is heated by the current and starts an
exothermic chemical reaction that releases the
aerosol. The minimum amount of energy needed to
start the reaction is created by applying 12V/0.8
Amps for 3-4 seconds.
2. The internal wiring of the activator can be inspected
by measuring the internal ohm resistance of 2 ohm
+/- 0.2 ohm using an ohm meter with a current less
than 5 milliamps. This inspection can be done in the
junction box mounted on the outside of the filter by
measuring the ohm resistance over the heat resis-
tant wires.
3. Check electrical activation of the Flame Guardian™
modules according to the above instructions.
True Functional test
A true functional check can be done by replacing the
Flame Guardian™ module with a detonation simulator.
A “Fire Like” condition can be simulated by removing
one of the spark detectors. After the fire alarm the det-
onation simulator will be activated showing a small
flash
1. Perform a Functional Test as described above.
2. Reset activated detector.
3. Press the SYSTEM RESET button on the
Guardian™ Panel.
4. Turn the control panel OFF for 20 seconds and then
back ON.
5. Reconnect the Flame Guardian™ module(s).
SYSTEM CONTROL PANEL
See System Control Panel Manual for detailed
Installation instructions.
Use Personal Protective Equipment
(PPE) to protect from exposure to
sparks.
