Intrinsically Safe Conventional Detector DCD-1E-IS(WHT)
The DCD-1E-IS(WHT) is an intrinsically safe conventional thermal detector with a fixed sensing temperature of 60oC, designed for use in hazardous areas.ara The unit also has a remote indicator output
Heat detectors are typically used in applications where smoke detectors are not suitable or if there is a danger of false alarms in smoke detectors.
Intrinsically Safe Conventional Detector Classification DCD-1E-IS(WHT)
Heat detectors are classified according to the highest ambient temperature at which they can be used safely and without the risk of false alarm. Classes are identified by letters A through G. In addition to the basic classification, detectors can be identified with a suffix to show that they are thermovelocimetric(suffix R) or fixed temperature (suffix S).
A1R
A1 – Detector Class (Maximum Application Temperature – 50oC, Static Response Temperature 54-65oC)
A – Temperature response (with rate of increase)
