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.

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.
