The Series 300 range of relay bases are part of System Sensor’s
Series 300 range of conventional detectors. Series 300 is a
family of conventional fire detectors designed using the latest manufacturing technology and incorporate an
array of advanced features, enabling them to "act conventionally, think intelligently.
The range consists of 12V non-latching, 12V latching and 24V latching versions to suit an array of fire and
security applications. All bases are fitted with a shorting spring to permit circuit testing prior to fitting the
detector and circuit continuity when a detector is removed during normal system operation. There is also a
tamper resistant feature, which when activated prevents the removal of the detector without the use of a tool.
