FEATURES

AC Sensing: The probe is supplied with AC, so it does not produce

electrolysis to cause cooling system corrosion.

Broken Wire Detection: If the wire to the probe is broken it will sound the

alarm.

Universal supply: Suitable for 12V or 24V, negative or positive earth

vehicles.

Self-test: On ignition turn on, it performs a self test by internally

duplicating low coolant or a broken probe wire. In self-test, the LED

ﬂ ashes twice and the beeper sounds 4 times.

Anti-slosh delay: If the radiator is not quite full and coolant sloshes

around, the LED ﬂ ashes after ½ second but the beeper will not sound

for 3-4 seconds. So there is a visual reminder to top up but no annoying

beeps.

External warning lamp: If the LCA1224 is to be mounted where it cannot

be seen by the driver, an external warning lamp output allows a dashboard

lamp to be used. The maximum rating for an external lamp is 0.5A max.

External warning buzzer: If the LCA1224 is to be mounted where it cannot

be heard by the driver, an external warning buzzer output allows a louder

(or more suitably located) buzzer to be used. The maximum rating for an

external buzzer is 0.5A max.

Low Coolant Alarm

LCA1224

FUNCTION

The Redarc LCA1224 is used in

a 12V or 24V automotive system

to monitor radiator coolant level

and provide a visual and audible

alarm if the coolant falls below the

chosen level. It can give warning

of a sudden loss of coolant (Eg

from a burst radiator hose) and

allow the operator to stop the

vehicle and switch off the engine,

to prevent any damage due to

overheating.

INSTALLATION REDARC strongly recommends that the probe be installed in the radiator by a suitably qualified radiator specialist. 1. 2. 3. 4. 5. 6. 7. Allow the engine to cool completely before commencing any work on the radiator. Select the position on the radiator header tank for the lowest safe coolant level (the point where alarm is to sound). Drain coolant (to at least below the probe mounting point).
