The pair of Control 26CT-LS Professional Ceiling Loudspeakers for Life/Safety Applications from JBL is a set of speaker assemblies designed specifically for use in fire alarm and/or emergency communication systems. The 26TCTS is built on the same platform as JBL's Control 26C and 26CT ceiling loudspeakers and is UL1480 UUMW Listed for safety systems.

The 150 watt continuous program power handling, 2-way coaxially mounted Control 26CT-LS loudspeaker is a compact ceiling speaker providing suitable performance in background or foreground music sound systems. The Control 26CT-LS is appropriate for use in a wide variety of applications from casinos and hotels to upscale restaurants, convention halls, and themed locations. 

The 6.5" woofer features a polyurethane-coated cone and pure butyl-rubber surround for long life, even in high humidity environments. An aluminum voice coil former provides extra cooling for greater long-term power handling. The coaxially mounted .75" titanium coated tweeter provides crisp, clear highs. Diffraction-loading of the tweeter provides wide, even coverage of the listening area. 

Input connection is conveniently provided on a removable locking connector, providing secure connection via screw-down terminals and allowing a system to be prewired before installing the speaker for fast snap-on convenience. Separate connector terminals are available for the input and for the loop-through wires, making it easy to jumper the speaker signal to additional speakers. The input terminal plate provides strain relief for either bare wire, plenum cable or ½ inch conduit (12 mm I.D.). 

The terminal box is securely enclosed to meet safety codes. The speaker trim and grille are paintable to match any decor. A paint shield is provided for covering the drivers while painting the rim. 

Installation of the Control 26CT-LS is quick and easy. The loudspeaker is packaged complete with the backcan, grille, support backing bracket, and tile rails. The entire installation can be accomplished without requiring access above the ceiling. A template is provided for marking the cutout. An included C-shaped support backing plate can be installed from below through the cutout to reinforce the top of the ceiling material. 

Tile bridge rails are included which can be screwed onto the C-plate to extend support to the T-channel grid in suspended ceiling installations. After the speaker is fitted through the cutout, it is held securely in place via three mounting tabs which tighten onto the C-plate, if used, or directly onto the ceiling material. 

The Control 26CT-LS backcan is made of formed steel. An attachment loop is provided on the backcan for cabling to the building structure as a secondary support in seismic areas or where required by code. 

The ceiling loudspeaker includes a 60W multitap transformer for use in either 70.7V or 100V distributed-line systems. Taps are selected with a rotary switch conveniently located on the front panel, but protected under the grille, so that the speaker does not have to be removed to adjust tap settings. 

All JBL Control Contractor loudspeakers - both ceiling speakers and surface-mount models - are designed with a similar sonic signature, allowing for mixing and matching of the various models within an application, providing a similar tonal character throughout the entire listening area. 

High power handling, wide frequency response and low distortion make the Control 26CT-LS capable for use in sound systems requiring a higher fidelity sound from ceiling loudspeakers. Their performance ability ensures accurate sound character, providing enveloping sound throughout the listening area.
