The Honeywell OELD (Optima Excel Local Display) is a smart junction box providing non-intrusive remote maintenance. A local interface is now included (via magnet) for configuration.  For use with Searchpoint Optima Plus and Searchline Excel flammable gas detectors. Available in Aluminium Alloy suitable for marine deployment or 316 Stainless Steel.  All versions have five cable entries, blanking plugs are supplied for those unused, one entry is needed for the sensor connection.

Optima Excel Local Display (OELD) has integrated Bluetooth for remote access using the OELD app installed on an intrinsically safe smartphone.  Tasks such as checking detector status, reviewing event logs, specifying target gas, adjusting alarm set points and calibration can all be executed without the need to open the detector, removing the requirement to declassify an area. The remote wireless functionality also helps with detectors in hard to reach areas.

The smart junction box has an LCD. Sensor output, real-time readings, bar chart representation, units of measurement (LEL, PPM), status icons for alarm and maintenance information are all shown. Operational status is indicated by backlit colour. Blue indicates Bluetooth connectivity, Green normal, Yellow fault/maintenance, Red alarm.

The gas detector can be mounted either directly or remotely to OELD to suit any application.

Ordering Information

Where replacement part indicated, a local user interface has been added to OELD operated via magnets. This allows the menu access, even without a Bluetooth connection.

OELD with UL certification can only be set up via Bluetooth (unlike the ATEX version that also has a magnet interface). For ‘physical’ configuration/maintenance, the XNX should be used instead which includes a magnet interface.
