CAH330 Analogue Heat Sensor, Heat
Heat sensors are suitable for dusty environments or environments
where smoke is likely to be present under normal operating condi-
tions . The CAH330 can be programmed to operate in A1R,BS or
CS mode of operation depending on the required application and
sensitivity requirements .
The status LED can be programmed to either be permanently off
under normal conditions or to pulse in order to confirm that it is in
communication with the CF2000 control panel .
CAB300 Analogue Sensor Base
Short Circuit Isolators
Each of the sensors in his range contain an integral short circuit
isolator, which operates between the -VE COM IN terminal and
the -VE COM OUT terminal . The isolator operates in conjunction
with the CF2000 Control Panel when a low parallel resistance fault
of typically 200Ω is presented between the+VE and -VE of the
loop wiring .
