General Information

The System Sensor RTS451KEY(A) is an automatic fire de­tector accessory designed to test remotely located duct and
beam detectors. For 4-wire detectors, the RTS451KEY fea­tures a multi-colored LED that alternates between steady
green and red. Green indicates power and that the detector
board is in place. Red indicates alarm. For 2-wire detectors,
the LED will show red for alarm. Consult the detector in­stallation instructions for additional information.

The National Fire Protection Association has published
codes, standards, and recommended practices for the in­stallation and use of this product. It is recommended that
the installer be familiar with these requirements, with local
codes, and any special requirements of the local authority
having jurisdiction.
