Aritech DB950R 950/990 Series Low Power Relay Base

The DB950R incorporates a low power relay to control field equipment such as automatic door closers. It provides a set of voltage-free relay contacts controlled by the remote output of a 950 or 990 series detector.

Unique Addressing

A unique, patented addressing method provides simple, user-friendly and accurate identification of detector location whereby a coded card, inserted in the base, is read by any detector as it is plugged in. All the sensing electronics are in the detector, but the location information is held in the base. Addressing errors during maintenance and service are eliminated. Pre-coded and pre-numbered address cards are also available. These address cards simplify and speed up installation and commissioning.

Installation

Robust, multi-wire screw terminals allows cables to be connected with ease, providing a secure connection platform. The relay output offering a standard change-over contact is integrated into the detector base.

Operation

The relay output is activated by the remote indicator output of the detector installed on the base. Under normal conditions, this output activates whenever the installed detector is in alarm. If the control panel allows the functionality, the remote indicator output may be individually controlled and programmed, allowing for a low cost, potential free relay output to be available for basic control applications.
