The Optima Excel Local Display (OELD) is a smart junction box for the Searchpoint Optima Plus and Searchline Excel infrared detectors for flammable hydrocarbons. The OELD includes an LCD screen for gas information, a "traffic light" indicator for at-a-glance detector status, and Bluetooth® connectivity for simplified, non-intrusive maintenance. Simply pair the OELD with our intrinsically safe, ruggedized smartphone; then use the OELD smartphone app to interact with the gas detector from up to 10 meters (30 feet) away. For maximum flexibility, the gas detector can be mounted either directly or remotely to OELD to suit any situation.


When you pair a smartphone with OELD, you can perform many tasks for your Searchpoint Optima Plus and Searchline Excel detectors wirelessly and from a convenient position.

Use the OELD mobile app to specify the target gas, configure alarm set points, perform one-man calibrations, access event logs, perform diagnostics, check detector status and more with no need to go back and forth to the control room, or open the enclosure on your gas detector. That means no hot-work headaches like obtaining permits, declassifying the area or adding more manpower.

For detectors in hard-to-reach locations such as a duct, you can position the corresponding OELD remotely in an easy-to access location and use the OELD smartphone app to interact with the detector wirelessly.


OELD has bright indicator lights visible from a distance, where green indicates normal operation, yellow indicates a fault or maintenance and red indicates an alarm. The LCD screen clearly displays real-time readings on detector status, including the gas being monitored, the local gas concentration and units of measurement??so you have easy access to status information.


The OELD smartphone app delivers the familiar user experience you expect?combined with gas detection technology designed to keep you safe while making your job easier. It simplifies detector maintenance and is acost-effective way to get even more value from your Searchpoint Optima Plus or Searchline Excel gas detectors.
