Product Description
It works on the linear detection principle, in which a heat-sensitive insulator between two spring-steel conductors breaks down at the rated activation temperature of 356 F (180 C) and signals the detection and actuation module. Weighing approximately 75 g, the element is intended to be routed along the equipment it protects, giving continuous coverage at the point of hazard. It is used with ANSUL CHECKFIRE electronic detection and actuation systems in demanding environments such as engine compartments. The ANSUL 439478 is a linear heat detector supplied as a 5 ft (1.53 m) detection element for use within ANSUL vehicle and industrial fire suppression systems.

Frequently Asked Questions
What is the ANSUL 439478?
It is a linear heat detector element measuring 5 ft (1.53 m) with a fixed 356 F (180 C) activation temperature, used in ANSUL fire suppression systems.
How does the linear detector operate?
A heat-sensitive insulator separates two spring-steel conductors. When the rated temperature is reached, the insulator breaks down and the conductors make contact, signalling the detection module.
Which system is it compatible with?
It is used with ANSUL CHECKFIRE electronic detection and actuation systems and ANSUL vehicle fire suppression systems.
How much does the detector weigh?
The ANSUL 439478 weighs approximately 75 g, which allows it to be routed along the equipment being protected.
