Announcing the Model 222S Detector

The detector also has a Loop Fail event monitor that remembers intermittent and current loop fail conditions and provides an indication of each type of failure condition. Each channel has an eight position DIP switch module that can be used to select one of eight sensitivity levels, Presence or Pulse mode of operation, one of four loop frequency settings, Fail-Safe or Fail-Secure operation, and channel disable. The 222S is self-tuning, provides complete environmental tracking, and is designed with built-in detector integrity test circuitry.
Similar in construction and operation to our Model G / 222 series, the Model 222S adds a pair of three position Call / Test toggle switches that can be used to simulate a continuous or momentary CALL output. This feature is useful when troubleshooting problems related to detector outputs and / or controller inputs.

* Two detector channels in a single unit
* Eight front panel DIP switches for each channel provide:
- Eight levels of sensitivity
- Presence or Pulse mode.
- Four loop frequencies
- Fail-Safe or Fail-Secure operation.
- Channel disable
* Front panel mounted Call / Test switch can be used to simulate CALL output.
* Loops are sequentially scanned to eliminate Crosstalk.
* Loop Fail “Event” Monitor remembers and indicates intermittent and current loop failures.
* Detector is self tuning and provides complete environmental tracking.
*Dual color (Red / Green), high intensity LEDs provide “Detect ” and “Loop Fail” indications.
*Complete built-in detector integrity test.
