The ceiling tile mounting box includes three M20 and two M25 knock-outs and a guide showing the size of hole that should be cut in the ceiling tile. Should the hole be cut too big, the mounting box includes slots that allow it to be screwed to the tile. The mounting box is available with one of two different sized retaining rings, one for use with Apollo detector bases (part no 45681-309) and another for sounder bases (part no 45681-310).
It is important that the integrity of fire resisting and/or acoustic performance ceilings is not compromised by using the ceiling mounting box. Approval for use should be obtained from relevant parties including local enforcing authorities and property insurers.
The Ceiling Tile Mounting Box has been designed to make the installation of detectors and sounders quick and easy prior to the fitting of a false ceiling. Detector and sounder bases can be fitted, wired and, if necessary, tested and commissioned before the installation of a false ceiling.
Detector and sounder bases can be fitted, wired and, if necessary, tested and commissioned before the installation of a false ceiling. Detector heads can even be fitted to the bases. When the false ceiling is in position, the mounting box can be slotted into place without disturbing the wiring.
A separate back box is not required as it forms part of the ceiling mounting box.
The mounting box can be used with tiles up to 25mm thick. Moulded springs on the back of the product automatically adjust to the tile's thickness while plastic blades imbed into the back of the tile to secure it in position. The mounting box is for use with all Apollo detector and sounder bases with the exception of the Intelligent Base Sounder for use with Isolating Base (part no 45681-266) and the 20D Isolating Base (part no 45681-321).
