HMI 201/01
4.8
Optional 120dB Siren
•
Identify suitable dry and protected location and securely mount the siren.
•
Remove approximately 25mm of the outer sheathing from the siren cable(s).
Extend the cable as required with wiring of the same gauge.
•
Lightly twist the strands of each inner wire and insert into terminals 7 and 1
of the connection block and tighten the clamping screws.
4.9
Connecting to a Power Supply
System -ve connection
•
The Master gauge requires a common -ve from each engine ignition gauge
circuit connected to terminal 1 of the connection block.
ve connection
•
The Master gauge requires a +ve supply from each engine ignition gauge
circuit connected to terminal 2 only for a single engine and 2 & 3 for a twin
engine installation.
Note: Twin engine installations must operate at the same voltage. Exhaust
Alert cannot accept a supply from one engine at 12V and the second engine
at 24V.

Post Installation Checks
5.1
Electrical Checks
•
Double-check all your connections and compare them with the appropriate
wiring diagram.
•
Switch ON the engine(s) ignition (power supply).
•
Both red and green lights should flash momentarily on the Master gauge and
the internal buzzer sounds.
•
If fitted the optional 120dB siren also sounds.
•
Switch OFF the engine(s) ignition (power supply).
•
Validate the system function by unscrewing the connecting plug on the
sensor and remove plug.
•
Switch ON the relevant engine ignition (power supply), for twin engine
installation do one engine at a time.
•
The self-test the buzzer should sound and the relevant Exhaust Alert red
warning light flash.
•
Acknowledge the alert (see Section1.3) and switch OFF the engine(s)
ignition (power supply).
•
Reconnect the sensor plug and tighten the screw, ensuring the pins are
correctly aligned and the rubber gasket is in place.
5.2
Pre-Engine Start checks
•
Verify all connections and cable runs are correct and secure.
WARNING:
Ensure there is no
power on the DC
circuit when the wires
are being connected.
NOTE:
A supply voltage drop
may cause the
Exhaust Alert to
restart and go
through its self-test
function. This may
occur when there is a
heavy power draw on
the batteries such as;
starting the engine,
using a bow thruster
or anchor winch.
