Quick Start Guide
Mount and Wire the Detector
Pay special attention to the conduit seal entry (Canadian Electrical Code Handbook Part 1,
Section 18-154). Also, lithium based grease is applied to the O-ring seal between the back-
plate and housing, as additional protection to avoid water ingression into the housing. Mount
detector using swivel mount or mounting bracket hardware.
