Bosch Security Systems Inc., Fairport, N.Y., announced its request-to-exit detectors have opened more than 2.5 million doors across the United States and is celebrating the product’s 20th anniversary. The detectors are installed in airports, office buildings, government facilities, hospitals, retail stores and many other applications throughout the nation.
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.
Recent improvements in the design of these products resulted in a 40 percent increase in reliability, helping to reduce service calls once the detectors are installed, the company stated. These detectors now 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 an auto-sensing 12 to 24 volt voltage regulator, reduces installation complexity and improves the efficiency of technicians in the field.
