Strobecom II 4090 Pre-emption Detector is Tomar’s advanced and durable pre-emption detector
The Strobecom II 4090 Pre-emption Detector is Tomar’s newest self-testing optical detector. Designed for use with Transit or Emergency Vehicles, it is easily mounted to observe the intersection where pulses can be sensed from up to 2500 feet away with military derived sensor technology. It is fully encapsulated and resistant to vibration as well as water and heat.
The 4090 family senses optical pulses from equipped emergency or transit vehicles and passes detection information to the associated processor. The manufacturer's sheet distinguishes standard detectors from ST variants with self-test capability. That distinction is relevant when replacing a detector in a system that monitors detector and wiring health.
Send the complete detector code and optical-processor model with your enquiry. Identify whether the existing installation uses self-test monitoring and which approaches need coverage. Ask Fortran to confirm the compatible variant and accessories before specifying a replacement; self-test functionality should not be assumed for a standard detector.
