2 Overview 2.2.2 Ceiling Mount Bracket Kit (1226A0355) The Ceiling Mount Bracket Kit (1226A0355) allows the OELD to be mounted to the ceiling. The kit includes two stainless steel ceiling mount brackets, bolts, and nuts. Note When considering the final mounting position using the Ceiling Mount Bracket Kit, consider the ability to see the OELD display when installed.
3.2 Mechanical Installation The OELD can be mounted in a number of ways using the integral mounting tabs. The OELD can be attached to flat wall surfaces or to Unistrut®. With the optional Pipe Mount kit, the unit can be mounted to pipe or pole. A ceiling mount bracket kit (1226A0358) is also available.
3.2.2 Optional Pipe and Ceiling Mount Installation The OELD may be fixed to a vertical pipe of 2" to 6" (50 to 150 mm) in diameter using the Pipe Mounting kit. This kit (1226A0358) consists of one bracket, two sets of carriage bolts, nuts and lock washers.
3.2.3 Using the Searchline Excel Mounting Plate The OELD may be fixed to the Searchline Excel mounting plate (2104D0237), which is included in the Searchline Excel kits. Two M10 tapped holes, ‘K’, are provided for mounting the OELD. Refer to the Searchline Excel technical manual for other details. The mounting plate fixings are not supplied.

Spare conductors must be suitably terminated. Wiring must be in accordance with local, national and/or company regulations. Exposed, bare conductors must be avoided. The following diagrams show the wiring of the OELD to Searchpoint Optima and Searchline Excel. For other sensors, refer to the manufacturer’s wiring details.
The earth bonding arrangement must ensure that the maximum peak voltage between the unit case earth and any field cable conductor is less than 350V. Voltages in excess of this can cause permanent damage to the units’ internal RFI protection filters. Connecting the OELD to Searchline Excel Cross-Duct (XD) OELD...

M25 or 3/4”NPT gland entry or conduit. The allowable conductor size for the terminals is 0.2 – 2.5 mm² (24 - 12 AWG). The OELD terminals will accept only wire sizes(solid- core or stranded) in this range. The temperature rating of the conductors should be greater than 80°C. The terminals should be torqued between 0.5 Nm to 0.6 Nm.
• reading resolution • gas name These settings are used to convert the 4-20 mA output from the sensor into a reading on the OELD display. WARNING Do not rely on the OELD LCD backlight status indication for safety-related purposes.
During the connection, the blue light of the OELD will indicate different states. Once the connection has been successfully established and if the sensor status is normal, the OELD blue light will be lit solid blue to indicate this. Connect the mobile device to the OELD as follows: 1.
The start-up and self-test sequence of the OELD takes approximately 60 seconds. During this time the user can check that each of the functions listed below are operating correctly as well as the OELD checking the correct operation of its critical circuits and processes.
Note The visual output of the OELD is derived from the 4-20 mA output of the sensor and/or status of the OELD unit. Use a suitable mobile device and the OELD app to connect to the OELD using Bluetooth® to access further diagnostic information. When used in conjunction with a Searchpoint Optima Plus or Searchline Excel, diagnostic and maintenance functions of the sensor can be accessed also.
During normal operation the instrument LCD shows a steady GREEN backlight. In case of a gas alarm or fault the red or yellow backlight respectively will flash. The screen is visible through the window of the OELD top cover and the display shows the gas concentration information both graphically and numerically, as well as other information including full scale range, measurement units, alarm / fault status etc.
6.3 Alternative Communications (SHC-1 Hand-Held Interrogator) If the OELD is being used in conjunction with the Searchpoint Optima Plus or Searchline Excel the sensor can be accessed using the Honeywell Analytics SHC-1 Handheld Interrogator and the SHC Protection Device. Use the dedicated terminals inside the OELD to do this.
7.3 Connecting to OELD Units 1. Standing in proximity to the OELD to which you want to connect, tap on the Detectors button on the main screen of the OELD 2. A list of detectors to which you have access will be shown. Should you require access to a detector that is currently restricted, tap on the device and simply scan the QR code of that device.
OELD. 7.5 Optima Plus Configuration The OELD Mobile App allows a user to configure a Searchpoint Optima Plus gas detector that is connected to the OELD unit. The configurable parameters are as shown in the table below.
7 OELD Mobile App 7.6 Calibration The OELD App allows a user to calibrate the Searchpoint Optima Plus or Searchline Excel. Note that this feature is not available for other gas detectors or sensors that may be used. Caution Searchpoint Optima Plus is factory calibrated and does not require routine calibration. In most cases, a re-zero will correct any inaccuracy in the gas reading.
8 Maintenance 8.1 General Periodically inspect the OELD and cabling for signs of physical damage. Clean the glass window with a damp cloth. Do not use solvents or abrasive cleaners. The OELD has no user serviceable parts. Honeywell Analytics recommend that the unit’s configuration and operation are checked annually as a minimum.
