SSK451 Multi-Signaling Accessory
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Notice:
This manual should be left with the owner/user of this
equipment.
General Information
The National Fire Protection Association (NFPA) has pub-
lished 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 au-
thority having jurisdiction. For further information, con-
sult NFPA 72 and 90A requirements.
The System Sensor SSK451 multi-signaling accessory is
designed for use with System Sensor DH100ACDC and
DH400ACDC duct smoke detector models and combines a
horn feature with the key-activated test and reset functions.
Green, yellow and red LEDs provide a visual indication of
power, trouble and alarm conditions, respectively.
To meet special code requirements of certain jurisdictions,
an optional PS24LO strobe can be easily added to the
SSK451 to provide visual alarm signaling. A “SMOKE” lens
can be added to the strobe.
The SSK451 can be wired such that its horn produces either
a continuous or a temporal tone. The SSK451 conveniently
installs to a double-gang electrical box.
