Power supply

The FS-1000E can be powerd from either type-3 alkaline battery ×2 pcs, or an external power source 9~30VDC depending on the application.
Optional power source can be from a long life lithium battery.

External output to a security system

Equipped with a form A (N/O) open collector output, FS-1000E can be connected to a security control panel. Alternatively the output signal
can be used to initiate a warning device e. g. bell, siren etc., when used with an external DC power supply.

Operation set-up by detection timer

The alarm will be activated only when the sensor detects a flame (ultraviolet rays) in accordance with the detection timer. The 4 following detection times are selectable by a slide switch located on the sensor body.

Other functions

・ The internal alarm sounder output is greater than 80dB at 3.3ft. (1m)
in front of the sensor. The internal sounder can be disconnected by cutting a jumper wire if required when using an external DC power supply.
・ Compact design enables FS-1000E to be installed at any location.
Easy separation of the sensor unit from the base simplifies installation and maintenance.
・ Low battery
When using a battery power source, low battery condition is annunciated by an internal buzzer and external LED.
・ Power up
When power is turned on, an alarm sound is activated. If no alarm sound is activated, check the power source.
