HOCHIKI DFG-60E WATERPROOF HEAT DETECTOR
INSTALLATION INSTRUCTIONS
General Description
The DFG-60E detector is designed for areas that are exposed to water, and provides reliable heat detection
with a slow or fast change in temperature. It is particularly suited to environments that are exposed to high
levels of condensation or are hosed down and has a wide operating margin allowing it to respond to both
slow and fast increases in temperature. It can also sense temperature reliably in a horizontal or vertical
position.
The detector is supplied with a set of flying leads for direct connection to the conventional zone and remote
LED (if required) and does NOT require any form of standard detector base.
