> LOUDSPEAKERS

The SENTRY6/RTC round, vandal proof metal cabinet loudspeakers is constructed from epoxy coated high grade steel and can be installed on solid ceilings or walls.Supplied with dual gland entries, which give the installer the option of loop in loop out termination thus avoiding the need for a separate junction box, these cabinets are both robust and aesthetically pleasing.

Although our standard finish is White, RAL9016, alternative finishes are available upon request. In compliance with BS5839 part 8, the SENTRY6/RTC incorporates a ceramic terminal and thermal fuse and is, therefore, suitable for voice alarm applications.
