Duct smoke detector accessories

The MSR-100 series advanced remote accessories work with the company’s duct smoke detectors to indicate problems, perform tests, and alert users to alarm conditions using special features. Available in the easy-to-install units are visual indication of detector pilot, trouble, and alarm functions; selectable audible indication of alarm and trouble functions; a buzzer silence function; and a lamp and buzzer test. For convenient, quiet service, a ringback feature enables the alarm buzzer to be silenced during problem inspection and remedy. The silenced buzzer will resume sounding upon correction of a problem condition, serving as a reminder to reset the silence switch to the normal operating condition. The optional strobe module continues to work even when in silent mode. A key-operated function enables users to test and reset from a remote location and verify that the detector is properly operating. For quick installation, a lever-operated “No-Tools” terminal block design eliminates the terminal strip screws and wiring required by similar products. The base unit, without strobe, fits into a single gang box.
