SYSTEMS TYPE “E1” AND “E”
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 or DET 4, etc. (see page DESP
13).
1) Check that the electrical connections are correct.
Do not open the water supply.
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.
The STOP circuit (duct valve and/or fan stop) should be off.
3) Execute the TEST operation. A pulse on the TEST button
simulates a spark.
The detectors turn active for 3 sec. The EXTINGUISHING
DET and the MONITORING DET LEDs light on for 3 sec.
When alarm stops DET LEDs blink.
The STOP LED lights on permanently and will require the
RESET button to turn off.
The WATER FLOW LED stays off.
The sound alarm sounds permanently and can only be
stopped by the RESET button.
The nozzle does not spray because the water supply is
closed.
The duct valve and/or fan stop relay (STOP circuit) are
permanently activated and can only be reset by the RESET
button.
Press the RESET button to switch off all the LEDs and
sound alarm, and to de-activate the STOP circuit.
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). Check that the
WATER FLOW lamp comes on for 3 sec while the nozzle
sprays. When alarm stops DET and WATER FLOW LEDs
blink, STOP LED is on permanently.
6) Press the RESET button to switch off all the LEDs and
sound alarm, and to de-activate the STOP circuit.
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 + and - 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 + and - terminals of the
detector and control panel. 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 control
panel 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
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.
