Fire Extinguishing System-Automatic - Regal 3760 Owner's Manual

FIRE EXTINGUISHING SYSTEM-
AUTOMATIC
Should the indicator light fail to come ON when the igni-
tion key is in the ON position check the 20 amp ignition
breaker at the key switch. The fire extinguisher system is
protected through this circuit.
Inspect the pressure gauge before each outing. The illus-
tration shows the ready and discharge condition of the
acutuator. Remove and weigh the unit (minus brackets)
every 6 months on an accurate scale ( Do not use any
hand held scales). If weight is below that shown on the
unit nameplate, it must be removed from service imme-
diately. If leakage is suspected, brush liquid soap on all
points of possible leaks, or submerge entire unit in clean
fresh water and watch carefully for 5 or 10 minutes.
Leaks will appear as tiny bubbles. If leakage is found re-
turn to the factory immediately for repair or replacement.
Remember the two most important requirements to as-
sure full charge and reliability of your Fireboy System are:
1. Visual inspection of the gauge and the actuator to de-
termine if it has actuated.
2. Weighing to determine the true contents of the agent
in the system.
All models from 75 cubic feet are rechargable. Recharg-
ing is possible only if the unit has leaked out verses los-
ing agent due to a fire.
Should the indicator light fail to come ON when the igni-
tion key is ON, first check the pressure gauge and actua-
tor to see if the unit has discharged.If not check the
breaker.
Next, using a continuity tester, check the electrical pres-
sure switch on the system bottle itself. Pull the molded
rubber connector off by pulling straight away from the
manifold, and place the probes of the continuity tester
directly on the spade connectors. This pressure switch
should have a closed circuit.
Next, check the continuity of the entire wiring circuit.
The indicator lamp is an LED (light emitting diode) and
cannot be tested with a continuity tester.
A simple method to test LED'S is to remove the lamp
and touch the red wire to the + terminal and the black
wire to the - terminal of an ordinary 9 volt battery. Should
the indicator lamp be faulty, replacement lamps are
available from Fireboy. Should the continuity of the
pressure switch indicate an open circuit, the system will
have to be returned to the factory for either replacement
or repair.
