APPLICATION
The EHT heat detector is used for Fire Prorective Signaling Systems.The detector shall be, cither a single-circuit type,normally open. The Detectors shall be rated for activation at eather 135 F (57 C) or 194 F (90 C) and shall activate by means of a fixed temperature /rate-of-rise thermal sensor. The rate-of-rise clemenr shall be activated by a rapid rise in temperature, approximately 15 F (8.3 C) per minute.
