The detector's sensors receive the transmitted pulsed radiation signals from the
Flash Source. The signals are then amplified and fed into an analog to digital
signal converter to be processed by the internal microprocessor.
When the signals drop below a prescribed level, the internal microprocessor will
compensate for them. This will allow the signal to be maintained even in severe
weather conditions. The data is sent to the output interface section. The signals
can be sent to a standard control panel or to a central computer.
The Series 200 Detector is available in three basic types:
1. Model OP-IF000X for short-range installation
2. Model OP-IF100X for medium-range installation.
3. Model OP-IF101X for long-range installation.
