Monitoring Functions:
Water aggregation
System SLSI issues an alarm when the attached liquid sensor LS-X
reports aggregate water.
An internal jumper selects automatic or manual reset
(power cycling) when water aggregation subsides.
Cable Fault:
System SLSI issues an alarm when the liquid sensor connection is
interrupted by e.g. cutting or shorting of the sensor cable.
Alarm Functions:
On water aggregation and cable fault, system SLSI will deactivate
the main alarm relay and issue visible and audible alarm.
Simultaneously, an auxiliary alarm- or valve relay is deactivated.
A front panel indicator shows the meausuring point status via a
three-color LED.
Controls:
Status Indicator and Buzzer.

Specifications:
One measuring channel servicing a liquid sensor type LS-X.
The setting of internal jumpers determines alarm function,
auxiliary relay function, buzzer and autoreset functions.
Alarm Output:
Fail-safe, floating SPDT in main alarm relay (energized in
the normal condition).
May be used for attachment to BMS or SMS (text) alarm message
module.
Fail-safe, floating SPDT in auxiliary alarm relay (energized
in the normal condition). May be used as auxiliary alarm output,
or to switch drive voltage for e.g. a magnetic valve or a siren.
Liquid Sensor type LS-X:
Sensor electrodes are gold plated for corrosin resistance.
Aggregation of sufficient water to make contact between electrodes
of the sensor will cause detection and alarm response.
Dim.: ø24 x 72 mm
Measuring Voltage: app. 900mVac 300Hz
Kabel 2½ mtr.
Other cable lengths on demand.
