Honeywell Searchpoint Optima Plus Infrared Point Gas Detector

Terminal/Installation Accessories: Provide a full range of hazardous area certified Ex e and Ex d junction boxes, as well as SHC-1 protective devices, to provide electrical protection for SHC-1 when using conventional terminal enclosures.

HART ®  communication protocol

Protocol advantage: HART ® Highway Addressable Remote Transformer is a widely used digital communication protocol that allows users to obtain real-time data, status indicators, and diagnostic information from smart field devices by superimposing digital signals on existing analog signals, without the need for additional field wiring, helping to reduce costs. If dedicated handheld devices are not required, engineers can use a single HART ®  Handheld devices access all HART devices on site ®  Enable the device and query HART at any position in the current loop ®  Signal, diagnostic information can be obtained without the need to go to the site, reducing maintenance costs.

The detector supports functions such as viewing gas readings, configuration, and diagnostic information, conducting collision testing, mA loop calibration, gas calibration, simulating alarms, faults, or warnings, setting device tags, IDs, and descriptions, viewing activity warning/fault and event history, forcing mA output to a specific level for testing, configuring real-time clock, configuring suppression, warning, and over range levels, configuring alarm thresholds, changing target gases, and password protected access.
