DETECT-A-FIRE ® (DAF) | ||
GENERAL INFORMATION DETECT-A-FIRE units are the heart of many Fire Protection Systems. These highly reliable devices have been a standard of the industry for over 45 years. Many hundreds of thousands of these units are now in use controlling the release of fire suppression agents such as FM200, CO2, water, foam, wet or dry chemicals. In some systems the device is used as an ALARM device. to sense overheat or fire, and alert personnel. In other systems, it is used as a RELEASE device, to sense fire and actuate fire attack systems.
The DETECT-A-FIRE also can be delivered as a part of a complete systen, built in an Ex-safe junction/mounting box. Ex-Certificates available: |

VERTICAL DETECT-A-FIRE UNITS Vertical detectors are designed for use
in both "ordinary" or "harzardous" locations.
For "ordinary" use, they may be mounted to any approved
junction box with 7/8 inch 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 leadwires are provided
on normally open vertical units (that close on temperature rise),
per UL requirement, to facilitate supervision of system wiring.
Units available in 2-wire and 4-wire-versions. |

HORIZONTAL DETECT-A-FIRE UNITS Horizontal Heat detectors 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 inch octagonal electrical boxes and surface mounting units are designed to mount directly on ceilings or on 4 inch electrical junction boxes. Canadian Electrical Code requires mounting only to an electrical junction box. |
