Lowell Clock/Speaker Combination Units

Lowell clock/speaker combination units provide an architecturally pleasing solution for recessed or surface-mount installation of a paging speaker and clock in a single, unified enclosure. These systems are a natural for school classrooms, sports/ recreation facilities, and medical or professional buildings of all kinds. This dual-function speaker and clock mounting solution is a practical approach that affords reduced fixture and labor costs while providing a clean architectural appearance.

The grille features a universal clock mounting bracket for problem-free installation of virtually any 10” or 12″ analog clock, and welded speaker mounting studs for installation of a standard 8″ speaker driver. Grille Model AP300 is designed for recessed installation to backbox Model PC312. For a surface version, use grille Model AP700 and backbox Model PC712.

This attractive grille is a two piece grille/subplate assembly. The grille is formed from a single piece of 18-gauge steel with a fine perforated face and integral frame border. The subplate features a clock cutout on one side and a speaker cutout on the other with provisions and hardware for attaching the universal clock mounting bracket in horizontal or vertical orientation. Additionally, the subplate features welded studs for installing an 8″ speaker driver. The subplate mounts to the grille (after clock bracket and driver installation) using four screws. The grille/subplate assembly then mounts to the backbox using hinges and screws for easy service access with security. Overall dimensions of semi-flush grille Model AP300 are 27.25″L x 17″W.
