Description

Constructed from stainless steel, the T54B is an extremely rugged heat detector that can be used to detect fires in the harshest of environments. The T54B can be used in environments with ambient temperatures up to 280°C and, being hermetically sealed, is impervious to most contaminants. The T54B is a simple device and therefore suitable for use in intrinsically safe areas when used with a suitable I.S. barrier. For reliable operation, it is recommended that T54B detectors have set points 20°C or 20% (whichever is higher) above the maximum temperature they will be exposed to in normal operation. Preferred factory preset temperatures range from 60° to 250°C; with normally open contacts. Other temperatures and normally closed contacts are available by request
