SYSTEMS TYPE “A” AND “B”
startup operations
It is advisable to put on the front panel of the PAN-705M
Control Panel the “NOT PRESENT” labels positioned on the
missed components, e.g. DET 2, DET 3, DET 4, etc. (see page
DESP 13).
1) Check that electrical connections are correct.
Do not open water
2) Apply voltage. The POWER LED will light on. All other LEDs
should be off. The sound alarm should not sound and the
solenoid valve should be de-energized and closed.
3) Execute the TEST operation. A pulse on the TEST button
simulates a spark. The detectors turn active for 3 sec.
The EXTINGUISHING DET LEDs light on for 3 sec, when
alarm stops they blink.
The WATER FLOW LED stays off.
The sound alarm sounds for 3 sec.
The nozzle does not spray because the water supply is
closed.
Remember that detectors are inactive for about 3 seconds
after power voltage is applied (power-on delay).
4) Open the water supply. Check pressure: should be 3-4 bar
at least.
5) Repeat the TEST sequence as per point (3). While the
nozzle sprays, be sure that water really flows by observing
the manometer or, if flow switch PAC-846 is provided,
observing the WATER FLOW LED lighted for 3 sec. on the
control panel. When alarm stops DET and WATER FLOW
LEDs blink.
6) Press the RESET pushbutton to reset the alarm memory
and bring the LED signals back to the stand-by state (LEDs
turn off).
To check the sensitivity of detectors, remove them from the
mounting frame and direct the front window to a light or a
cigarette lighter. In this way each detector can be tested in
turn, checking that the system is correctly installed.
List of possible malfunctions
1) The detector fails to operate with TEST.
Check the 24Vdc voltage on the +/- terminals of the
detector and the 24Vdc voltage pulse on the "T+" and "-"
terminals when pressing the TEST button.
If voltages are correct, the detector is faulty.
2) The detector is permanently in alarm.
Check the 24Vdc voltage on the +/- terminals of the
detector and power supply unit. If it is correct, and provided
that no light falls on the detector window, the detector is
faulty. If the voltage is incorrect or unstable, maybe the
power supply unit is faulty. The detector circuits could
generate alarm signals in response to intermittent power
voltage, even if the power-on delay will eliminate most of
this problem.
3) The WATER FLOW LED
(when flow switch PAC-846 is
installed) is permanently on and the sound alarm sounds,
while all other LEDs are off.
This signals a water leak in the solenoid valve due to rubber
diaphragm being jammed by dirt or having a malfunction.
Close the water supply and check. If necessary, open the
solenoid valve body.
4) One or more LEDs do not blink after an alarm.
Check that the corresponding switches, positioned on the
front panel circuit, are in "on" position (DIP switch 1-2-3-4 =
DET 1-2-3-4, DIP switch 5 = WATER FLOW).
Notice:
The detector is very sensitive. Movements of lights or
sun light penetrating trough openings in the duct may cause
false alarms.
