Honeywell Analytics HALO LED Junction Box with optional HART Port

If you need to see the sensor status of the Searchpoint Optima Plus point infrared Hydrocarbon gas detector at a glance, even from far away, the HALO Junction Box is ideal.

Through an optional intrinsically safe (IS) HART® connection point, the HALO Junction Box also provides helpful, non-intrusive interaction with a HART® handheld device.

The status is indicated clearly and easily using a "traffic light" colour scheme that is instantly familiar. A red flash indicates an alarm, the show of yellow indicates a fault/inhibit and the show of green indicates normal operation.

This system is beneficial as it allows anyone in the area to immediately see the status of any detector. If there are a number of detectors in an area or if a detector is hard to access, the HALO Junction Box makes things easy.
