Visonic's SRN-2000ET is the world's most flexible and reliable PIR detector, and is specially designed for energy management systems requiring high sensitivity and large detection coverage. Implementing Visonic's noted Super-Red Lens Library™ of 45 easy-to-change lenses, SRN-2000ET offers the most outstanding selection of lenses, saving time and money on every installation.
A unique "test point" can be used for pinpoint adjustments of the detection pattern as well as for locating background interferences. Special lens masking material is provided to enable masking detection zones exposed to interfering sources, such as cold and hot air ducts or outlets, moving objects, etc.
The SRN-2000ET detector operates on 12 VDC supply and can be integrated into virtually any kind of energy management system. It provides exceptionally high sensitivity with a standard coverage pattern of 18m x 18m (60ft x 60ft) / 100° that is adjustable even up to 35m x 35m (115ft x 115ft) to cover very large rooms, halls, etc.
The output is provided via a form 1C relay equipped with an operation reset timer that can be adjusted between 1 second to 20 minutes. When used with stand-alone air conditioners, the detector can be set to have a 3-minute delay period until renewed activation of the relay is possible.
