Fenwal Fire Detectors

Fenwal Detect-A-Fire (Vertical Mounting) Fire Protection

Fenwal Vertical Fire detectors (Detect-A-Fires) are designed for use in both "ordinary" or "hazardous" locations. For "ordinary" use, they may be mounted to any approved junction box with 7/8" diameter opening by using 1/2-14 NPT mounting nuts. The device may be wired in or out of conduit, depending on local preference and codes. Four lead wires are provided on normally open vertical units (that close on temperature rise), per UL requirement, to facilitate supervision of system wiring. Instruments are Underwriters Laboratory and Underwriters Laboratory of Canada listed and Factory Mutual approved for hazardous locations, when mounted in a suitable fitting.

Fenwal Detect-A-Fire (Horizontal Mounting) Fire Protection

Fenwal Horizontal Fire detectors (Detect-A-Fires) are designed for locations where appearance is a factor. The attractive, functional design lends physical protection of the unit while making it suitable for commercial, industrial, mercantile and public buildings, institutions and ships in non-hazardous locations (those classified as "ordinary" under the National Electric Code). Flush mounted units are designed to fit standard 4" octagonal electrical boxes and surface mounting units are designed to mount directly on ceilings or on 4" electrical junction boxes.

DETECT-A-FIRE® Units are precision temperature sensors. They must be mounted in an area (normally a ceiling) so that: 1. The detector spacing complies with both system requirements and requirements of the agency having local jurisdiction. 2. The thermal air path to the shell is not obstructed.
