Honeywell Brand Junction box Model HALO

Status at a glance

The HALO Junction Box enhances the Searchpoint Optima Plus point infrared Hydrocarbon gas detector* by providing a local display showing the sensor status at a glance, even from a distance.

It also gives convenient, non-intrusive interaction with a HART® handheld device through an optional intrinsically safe (IS) HART® connection point.

HALO uses three instantly recognisable ‘traffic light’ colours to indicate its status.

The LED light ring shows green to indicate normal operation, yellow to indicate a fault/inhibit and flashes red to indicate an alarm.

This allows anyone in the area to clearly and immediately see the status of any detector.

This can be particularly useful to identify operational status if the detector is located in a difficult to access area or if a number of detectors are located in the same area.

Internally, the box has a continuity plate with two earth connection points, and a 12-way terminal block.

The box lid has a three colour light ring (green, yellow and red), and optional connections for a HART® handheld device.

The light ring provides a status indication (see below).

The box is configured using a magnetic switch.

A magnet is incorporated into the blanking cap

which screws into the middle of the box lid

when not in use.

The following parameters can be configured:

Threshold for local alarm indication (red lights) can be set between 10 % and 65 %FSD

Brightness of green LED lights can be set to Full Power, Half Power or Off The optional Pipe Mounting Bracket is suitable for a

horizontal or vertical pipe, diameter 50 to 150 mm (2 to 6 inches).
