The SPT2000 system utilizes active infrared photo beams and/or microwave as range detection devices for both internal and external applications. The system utilizes solar-powered infrared transmission between synchronized transmitters and receivers. Depending on the application, several types of detectors from two beam paths to as many as 16 beams are available. (See Images Noted Below). Depending on the type of detector used, the range of the beam paths can be up to 660-feet. The system eliminates the need for hardwire connections between towers. This feature greatly reduces installation time and cost. An automatic graded alarm response system uniquely combines the ability to provide high levels of detection with a low potential for false alarms.
OPERATION
The SPT2000 system is comprised of multiple transmitters and receivers that can be housed within either a freestanding or a wall-mounted tower enclosure. The towers are of an ultra slim line design and provide a full 180-degree unobstructed view for the beams. The result is a device that adapts to all system configurations with ease. The Infrared beams draws very little power while in operation. Using the solar panel and a 48-amp battery supply, the beam units will perform for many years.
GRADED ALARM RESPONSE
The SPT2000 system-graded alarm response is designed to reduce false alarms while maintaining security levels. The system monitors the sixteen individual beam paths. When an object bigger than the vertical distance between the beam heads inside the same tower is detected, a beam response time of 40 milliseconds is employed. If a single beam is broken the system automatically sets the required beam break time to 500 milliseconds or more. This dual response reduces the likelihood of the beams responding to small animals or blowing debris, while still offering protection against a crawling intruder.
