DESCRIPTION:

The Series 300 range of relay bases are part of System Sensorís Series 300 range of conventional detectors. Series 300 is a family of conventional fire detectors designed using the latest manufacturing technology and incorporates 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. Before determining which relay base to use, please consult the control equipment supplier to ensure product
compatibility.

B312NL (12V Non-Latching)

The B312NL has been designed to provide interfacing between a Series 300 detector and 12V security control panels that do not provide a reset facility, as the relay base is self-resetting. Therefore, the relay base will automatically reset the Series 300 detector when a fire alarm condition no longer exists. While the detector is in alarm the LED will be on, although it will flash when an alarm check is performed. This base is also ideal for control of any electrical apparatus such as air conditioning systems or apparatus utilising a 12V power supplyinstead of a control panel.

B312RL (12V Latching)

The B312RL has been designed to provide interfacing between a Series 300 detector and a 12V fire system or security system that require an external contact to activate an ancillary piece of equipment. The relay is controlled directly from the detector. Therefore, in an alarm condition both the detector and relay base will latch into alarm, and can only be reset by removing the supply voltage from the detector. The base can be used with 4 wire security systems that have a reset facility.

B324RL (24V Latching)

The B324RL has been designed to provide interfacing between a Series 300 detector and 24V fire control panels or power supplies that require an external contact to activate an ancillary piece of equipment. The relay is controlled directly from the detector. Therefore, in an alarm condition both the detector and relay base will latch into alarm, and can only be reset by removing the supply voltage from the detector. A break off tab allows the base to be connected to a range of fire control panels. This tab should be broken when there is little current flow or no current limiting resistor such as when used as a stand-alone system powered by a 24V supply. All System Sensor products are covered by our extended 3 year warranty.
