Authority Having Jurisdiction(AHJ)should be consulted before installation. DETECT-A-FIRE MOUNTING D-A-F detectors are not position sensitive. Horizontal and vertical detectors refer to the most common mounting configuration for that detector. However each type can be mounted either horizontally or vertically depending on the application and installation requirements.

CONSTRUCTION • Stainless steel shell sensing element. Cold rolled steel mounting facility. Off-White finish. • #18 AWG Teflon TM insulated wire is used on detectors exposed to temperatures up to 375°F. • #16 AWG TGGT insulated wire is used on detectors exposed to temperatures above 375°F. MODIFICATIONS • Add ULC Label to any temperature setting. • Add fluorocarbon coating for better corrosion resistance on select models and temperatures. (Models 27120-22, 27121-20, 28020-3, 28021-5. Maximum temperature is 5000F.) • Add extended leadwires on select models and temperatures. 4 F-12-0-001 FENWAL Effective: June 2020 CONTROLS
