General Information

The National Fire Protection Association (NFPA) 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. For further information, con­sult 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.

Figure 3: Test Coil Installation

Wire the SSK451 as shown in Figure 1, for DH100ACDC
duct smoke detectors, or Figure 2, for DH400ACDC duct
smoke detectors. Limit wire runs to 25 ohms or less per
interconnecting wire.

Test Coil Installation

NOTE: When the SSK451 is used with a DH400ACDC
duct smoke detector, a test coil, part number COIL,
must be ordered separately. When the SSK451 is
used with a DH100ACDC duct smoke detector, a
test coil is not required.

The COIL is installed in the DH400ACDC duct smoke de­tector housing as shown in Figure 3. Please follow the in­structions enclosed with the COIL for proper installation of
the COIL to the DH400ACDC duct smoke detector.
