10 Conventional Products—2412, 2412TH, 2424, and 2424TH Direct Wire Photoelectronic Smoke Detectors
Dust covers can be used to help limit dust entry to the detector, but they
are not a substitute for removing the detector during building construction.
If detectors are mounted in a construction area, with or without the dust
cover in place, each detector should be thoroughly cleaned, inspected, and
tested after construction is complete. Remove any dust covers before
placing the system in service.
This detector includes a tamper-proof feature that prevents removal of the
detector without the use of a tool.
To make the detector tamper-proof:
1.
Break off the smaller tab at the scribed line on the tamper-proof tab on
the detector mounting bracket (Figure 2).
2.
Install the detector.
To remove the detector from the bracket once it has been made
tamper-proof:
1.
Use a small screwdriver to depress the tamper-proof tab located in the
slot on the mounting bracket.
2.
Turn the detector counterclockwise for removal.
The tamper-proof feature may be defeated by breaking and removing
the plastic lever from the base. However, this prevents using the
feature again.
