VERTICAL DETECT-A-FIRE-UNITS
Fenwal Vertical detectors 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 (FM) approved for hazardous locations, when mounted in a suitable fitting.
Fenwal Part Numbers include : 27120 28020 27121 28021
Temperature Settings (degrees F): 
140 160 190 210 225 275 325 360 450 500 600 750

Fenwal DETECT-A-FIRE® (D-A-F) thermal detectors are UL Listed (UL of Canada available upon request), and FM Approved detection and release devices for use with fire detection systems to activate alarms and extinguishing systems. This Rate Compensated device combines the best features of both fixed temperature and rate-of-rise detectors.

• Hazardous Locations: For Class I, Division 1 and 2 locations install the D-A-F Unit in a listed explosion-proof enclosure with a minimum thread engagement of five full turns. No non-conductive material is to be placed on the threaded joint of the D-A-F Unit or in the listed explosion-proof enclosure. For Division 2 locations assure that a protective ground terminal is provided in the listed explosion-proof enclosure when flexible metal conduit is used.
  
  

• Non-Hazardous Outdoor Locations: Mount the D-A-F in a Listed NEMA Type 3 outlet box, cover and conduit, with 1/2- 14 NPT threads and a minimum thread engagement of 5 full turns. Use pipe plugs with RTV silicone rubber sealant, a rubber gasket and self- sealing screws to attach the cover, and PTFE thread sealtape on the D-A-F threads. For additional requirements consult the local fire department, the National Electric Code and/or the local authority having jurisdiction in the area.
  
  

As part of the recommended maintenance procedure, perform a visual inspection of the Fenwan DETECT-A-FIRE® unit in accordance with NFPA 72 guidelines. During the visual inspection, verify that the sensing shell is free of dents, dings or build up of foreign matter of any kind. If the shell is dented or shows signs of any physical damage, replace the unit immediately. If a build up of dust has accumulated on the unit, clean the unit with a vacuum or soft dry cloth. If the shell has been painted, replace the unit. Be careful not to damage the unit in any way.
Note: Some units are factory coated. Do not confuse these with units that were painted by the owners.
