2091-SD STROBECOM II OPTICAL PREEMPTION DETECTORS

TOMAR 209X–SD 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 Detectors are used with TOMAR 2000 Series Optical Signal Processors to inform the traffic control system of the presence of designated vehicles.

Using 209X–SD Detectors and Strobecom II throughout your traffic control system reduces emergency response time, allows emergency vehicles to travel with greater safety, and improves transit vehicle timeliness.

ONLY TOMAR 209X–SD Detectors offer these important features:

• 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 parallel detector installation without any special cabling for enhanced detection around corners and over hills.

TRUE 10 Year Warranty!

HOW IT WORKS:
The emergency vehicle uses a special strobe light to transmit a continuously flashing optical signal. The STROBESWITCH™ receives this signal, and if the signal format is correct, activates a relay. The relay contacts may be used to control security gates, fire department garage doors, and other devices. Signaling is optical by line of sight, and it can operate indoors or outdoors, in bright sunlight, or in any weather. The unit is not susceptible to radio frequency interference, and uses digital frequency discrimination to reject unwanted signals, such as flashlights, emergency vehicle lighting systems, flashing signs, etc.  

Specifications:

Range: 1000 feet typical, but depends on intensity of strobe emitter
Field of View: 10º vertical, 90º horizontal
Signal Acquisition Time: 0.64 seconds
Function Indicator:
The unit has a red LED that illuminates whenever a proper optical signal is received. The LED is visible thru the viewport and can be seen for 25 feet or more. This feature can be used with the optional Hand Held Tester to verify the unit’s operation.
Frequency:
F14 = 14.035 Hz ± .25 Hz ( high priority )
F10 = 10.000 Hz ± .25 Hz ( low priority )
