According to the company improvements in the design of the products has resulted in a 40 percent increase in reliability—helping to reduce service calls once the detectors are installed.

The detectors also include built-in spike protection, which eliminates 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 that make configuration easier and a new auto-sensing 12 to 24 volt voltage regulator, reduces installation complexity—improving the efficiency of technicians in the field.

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

The DS150i and DS160 devices 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 and are wall or ceiling mountable.
