How to specify an Infrared Detector Head Standalone

1.  Delphian offers two infrared detector heads: 

• the Determinator measures the percent of combustible gases 

• the Remediator measures percent by volume of combustible gases. 

These detector heads consist of an interface module, a processor module, and a sensor in an explosion proof housing.
Choose either an aluminum or stainless steel sensor.

	Infrared Detector Head Part Numbers (complete: includes conduit box, interface and processor modules)
	Determinator	(combustible LEL) aluminum	364-850-01
		(combustible LEL) stainless steel	364-850-02
	Remediator	(combustible % volume) aluminum	364-855-01
		(combustible % volume) stainless steel	364-855-02

Consider the following options:

• Splash/Dust Guard for severe environmental and operational conditions (part number 361-707-02).

• Lightning arrestor where high-energy transient suppression is necessary.

• SLAM (local alarm relay module) with relays for 3-gas alarms and one for fail. It connects to the Interface Module. The SLAM extension kit includes a separate explosion-proof housing .  A SLAM must be ordered separately with the sensor extension kit.

• Reclamation Adaptor to allow the sensor to be mounted externally to a duct or area outside of the sensor's temperature range.

2. (See Step 7* ) Select an owners manual for each gas category to be detected. Specify tags and engraving (if required). Owners Manuals & Tag Part Numbers

3. (See Step 8 *) Select spare parts. See table below.

4. (See Step 9 *) Choose a calibration kit and a gas for each different type of gas to be detected.  Calibration Part Numbers
