Yes, but only when using the CTM-530E-I interface module and if the installation is in compliance with Protectowire Control Drawing IL-1622.

The CTM-530E-I is FM-approved and provides intrinsically safe connections suitable for monitoring CTI Linear Heat Detectors installed in Class I, II or III, Division I, applicable groups A, B C, D, E, F and G classified areas.

Protectowire Control Drawing IL-1622 provides instruction on how to properly install both the CTM-530E-I and CTI Linear Heat Detector to comply with the requirements for intrinsically safe circuitry.
