Since 1968, TOMAR Electronics Inc. has designed and manufactured industry leading emergency signaling products in the U.S.A. From the latest in LED lightbars, LED lightheads, sirens, and optical preemption systems to audible and visual warning signals for industrial applications.
STROBECOM II is an Optical Preemption System designed and engineered to help emergency service professionals reach their destination quickly and safely. By communicating with the traffic control system located at each intersection, the approaching emergency vehicles are given a “green” light before entering the intersection, thus creating the ability to move through heavy traffic situations. STROBECOM II significantly increases the efficiency of the emergency response teams and allows them to reach their destinations SAFELY with DECREASED RESPONSE TIMES.
The Optical Signal Processor (OSP) receives the electrical signals from the optical preemption Detectors. While being received, the signals are processed to determine if the vehicle is a valid emergency or transit vehicle.
The OSP is connected directly to the preemption inputs of the traffic controller in the intersection in which it is installed. When a vehicle’s signal is accepted as valid, the OSP sends a preemption request to the proper input of the traffic controller.
The traffic controller then safely manipulates the traffic signals according to a preprogrammed algorithm. Depending on where the traffic controller was in its normal routine the vehicle will receive a “Green Light” after a minimum of 3 or more seconds. Traffic signals which are already green will stay green until the vehicle passes.
If multiple vehicles are being received, they are prioritized to determine which vehicle should be given the right of way. If vehicles are of equal priority, right of way is given on a first-come, first-served basis.
TOMAR’s 209X–SD and ST model Optical Preemption Detectors sense the optical pulses emitted by properly equipped emergency or transit vehicles. Mounted to observe the approaches of an intersection, 209X–SD and ST Detectors are used with TOMAR 2000 and 3000 Series Optical Signal Processors to inform the traffic control system of the presence of designated vehicles.
The 209X-ST detectors incorporate a self-test feature for true closed loop detector and wiring welfare monitoring. Each 209X-ST detector includes a small infrared LED which periodically injects a special test signal into the detectors photo sensor. The 3140 OSP receives the special test signal and therefore knows that the detector is fully functional. Should a detector fail self-test a front panel indication and an entry in the 3140’s logs indicate the problem.
Using 209X-SD or ST detectors and Strobecom II throughout your traffic control system reduces emergency response time, allows emergency vehicles to travel with greater safety, and improves transit vehicles timeliness.
The TOMAR 209X-SD and ST Optical Detectors offer the following features and benefits:
- Closed loop self-test for detector welfare, monitoring and reporting (ST models only).
- Military derived sensor technology for direct sunlight rejection and detection performance unmatched by ANY other system.
- Fully encapsulated electronics for complete resistance to water, heat, and vibration.
- Complete electronics protection from damage due to miswiring or electrical transients.
- Wide field of view option for uncompromised detection even in untethered span wire applications without the risk of side street activation.
- Simple advanced detector installation without any special cabling for enhanced detection around corners and over hills.
The 2097 Detector/LED confirmation light assembly combines one of TOMAR’s Strobecom II detectors with a low-voltage, super-bright, LED confirmation light in one easy to mount and wire assembly. The weather-proof tilt/swivel mounting hardware is constructed of corrosion resistant anodized and powder coated aluminum and stainless steel with galvanized steel locking nuts.
When used with a model 3140 Optical Signal Processor and a model 2087 LED confirmation light driver, the 2097 receives a vehicles emitter signal via the Strobecom II detector and provides a visual feedback signal to the emergency vehicle driver that his signal has been received and is eligible to receive preemption.
The LED lamp used in the 2097 comes directly from TOMAR’s LED warning light line ensuring that it is both long-lived and powerful enough to be seen on the brightest of sunny days. The 2097’s LED beam pattern is controlled to provide warning to the emergency vehicle driver without being blinding to other traffic even at night.
