Could you please confirm me why Zip tie is not permitted to secure the detector? If you have any reference please share from NFPA 72 or NFPA 70.
In addition, if we use GI wire to secure the detector in Shed, is it okay???
Please make reference to Chapter 10 Fundamentals - under Section 10.3 Equipment - under Subsection 10.3.2 of the 2019 NFPA 72. Installation of the detectors are to follow the manufacturer's published instructions.
For example - a Notifier B612CP detector base is to be mounted directly to 3 1/2 "; 4" octagonal box; or 4" square boxes using the screws provided to attach the base to the box.
