Sensor Unit

A quadruple detector sensing module is located within an aluminium alloy housing which is mounted by means of an adjustable bracket permitting alignment in both vertical and horizontal planes.

The Type 5010 Sensor housing is equipped with an air hose spigot, signal cable gland and internal screw terminals. The sensing module fits to the housing by means of a connector and thus may be readily de-mounted (upon removal of the housing cover) without disturbance to cable connections.

A type 5011 Sensor is available which employs an external "Air Knife" and has a pressurised case.

Controller

The control module is easily de-mountable from the housing and connects to the sensor by means of a ten core cable. These terminations, together with supply and output contact connections are via two part screw terminals thus enabling installation of the housing and site cables prior to fittment of the module. Standard housings have a high level of ingress protection (IP67).

The unit incorporates a user programmable DIL switch to set the options which include detector sensitivity setting, auto/manual reset sequence selection, and one-shot/coincidence voting for the alarm and trip/shutdown outputs.

The sensor air pressure and signal cable connections are fault monitored/fail safe. The unit incorporates an aux. fault input & common fault output contact.
