Bosch Request-to-Exit Detectors

The enhanced DS150i and DS160 request-to-exit detectors by Bosch Security Systems of Fairport, N.Y., detect motion in their coverage area and signal an access control system or door control device. They can be used with single or double doors.

The detectors include built-in spike protection, eliminating the need to add a separate module to prevent significant voltage spikes on the relay contact. This feature, along with the use of dip switches and a new auto-sensing 12V to 24V voltage regulator, reduces installation complexity — improving the efficiency of technicians in the field, according to the company.

Sound output has also been increased through the implementation of a more effective sounder and circuit design. Users can increase the volume by more than 10 percent over previous models to fit their individual needs and preferences.
