Duct Smoke Detector Accessories Expand the versatility of the Innovair™ line of duct smoke detectors with System Sensor notification and test accessories. Available Accessories APA151 Piezo Annunciator MHR Mini-Horn, Red MHW Mini-Horn, White PS24LO Mini-Alert Add-on Strobe (red) PS24LOW Mini-Alert Add-on Strobe (white) PS12/24SLENSW Wall-Mount “SMOKE” Lens RA400Z Remote Annunciator RTS451 Remote Test Station RTS451KEY Remote Test Station with Key SSK451 Multi-Signaling Accessory These products add functionality to the duct detection system by allowing quick, convenient inspections at eye level and effective audible and visible notification options. All System Sensor duct detectors and accessories are UL listed. The APA151 piezo annunciator, which replaces the APA451 with a new, improved look, provides an audible alarm signal, a red LED to indicate alarm status, and a green LED to indicate power status. It is intended for use with System Sensor 4-wire conventional duct smoke detector applications without a system control panel, to comply with NFPA 90A. The MHR and MHW SpectrAlert® Advance mini-horns feature temporal or continuous tones at high and low volume settings. These horns are ideal for applications, where a small notification device is desired. Their small footprint allows mounting to single gang back boxes for aesthetically sensitive applications. The PS24LO and PS24LOW mini alert add-on strobes can be attached to the SSK451 multi-signaling accessory for visual alarm signaling. The PS12/24SLENSW “SMOKE” lens is available to meet special code requirements in certain jurisdictions. The RA400Z remote annunciator is designed for both conventional and intelligent applications. The red LED provides visual indication of an alarm condition. Agency Listings The RTS451 and RTS451KEY remote test stations are automatic fire detector accessories designed to test duct detectors from a more convenient location. For 4-wire detectors, the RTS451KEY test station features a multi-colored LED that alternates between steady green and red. For 2-wire detectors, the LED illuminates red for alarm. The SSK451 multi-signaling accessory is designed to work with System Sensor 4-wire conventional duct smoke detectors. It combines a horn feature with the key-activated test and reset functions. Green, amber, and red LEDs indicate power, trouble, and alarm conditions, respectively.
