USEr OPERATION
FIRE DETECTION OPERATION
In the event of a fire being detected the appropriate zone alarm LED will illuminate and the internal buzzer will operate. If external
sounders and or beacons are fitted they too will operate. If connected, the gas solenoid valve will close.
Pressing the
MUTE
button will turn off the sounders and beacons, including the internal buzzer. However the zone light will remain
on until the smoke, heat etc. has cleared and the
RESET
button is pressed. If the
RESET
button is pressed whilst a detector is
still in the presence of sufficient smoke, heat etc. the zone will re-trigger and the sounders and beacons will re-activate. Also if
the other fire zone or a gas or bilge alarm occurs the sounders and beacons will re-alarm.
If it is needed to re-trigger the sounders for evacuation, first press
RESET
then press the
TEST
button. The
TEST
button will put
fire zone 1 in to alarm and hence operate the sounders.
Once all conditions have been cleared and
RESET
the gas solenoid valve can be operated by pressing the
VALVE ON
button. It
is important to check all pilot lights on the gas appliance and ensure they are ignited where necessary. The ED510 has a general
alarm output relay which can be used for various purposes including the shutdown of air conditioning, HVAC etc.. Any items
connected to these contacts should be checked for correct operation.
WATER LEVEL OPERATION
In the event of bilge water being detected the appropriate level zone alarm LED will illuminate and the internal buzzer will
operate. If external sounders and or beacons are fitted they too will operate. If bilge pumps are connected they will be activated
to pump out any water.
Pressing the
MUTE
button will turn off the sounders and beacons, including the internal buzzer. However the zone light will
remain on until the float switch has deactivated and the
RESET
button is pressed. Also if the other fire zone or a gas or bilge
alarm occurs the sounders and beacons will re-alarm.
If you need to manually activate the bilge pumps this can be achieved by pressing the appropriate level zone
TEST
button. To
manually turn off pumps press the
TEST OFF
button. There is an
ON DELAY
which determines time to activate the pumps and
also
RUN ON
time which determines how longs after the pump should run which is set using the potentiometers on the underside
of the top PCB board. (See page 10 for adjustment settings)
GAS DETECTION OPERATION
In the event of a gas being detected the appropriate zone alarm LED will illuminate and the internal buzzer will operate. If external
sounders and or beacons are fitted they too will operate. If connected, the gas solenoid valve will close.
Pressing the
MUTE
button will turn off the sounders and beacons, including the internal buzzer. However the zone light will
remain on until the gas sensor has cleared and the
RESET
button is pressed. Also if the other fire zone or a gas or bilge alarm
occurs the sounders and beacons will re-alarm.
Once all conditions have been cleared and
RESET
the gas solenoid valve can be operated by pressing the
VALVE ON
button. It
is important to check all pilot lights on the gas appliance and ensure they are ignited where necessary. The ED510 has a general
alarm output relay which can be used for various purposes including the shutdown of air conditioning, HVAC etc.. Any items
connected to these contacts should be checked for correct operation.
FAULT CONDITION
In the event of faulty wiring of peripherals the appropriate zone fault LED will illuminate. Action will need to be taken to find the
cause of any fault condition and ensure continued functionality of the ED510.
