B.
Mounting.
The Model 224XSTHI strobes are designed for hearing impaired applications and should
be installed per the NFPA 70 & 72, STATE and LOCAL CODES. Alternate installation locations
and/or orientations should only be performed with the approval of the authority having jurisdiction.
Reference Figure 1 for the light dispersion pattern of the 224XSTHI.
To reduce the risk of fire or explosion, do not install in a hazardous location if the
operating temperature exceeds the ignition temperature of the hazardous atmosphere.
Refer to the product nameplate for operating temperature markings.
The Model 224XSTHI has provisions for mounting to _” N.P.T threaded pipe. The
conduit run from the device to the splice box shall not be larger than 10 inches. Before mounting,
ensure that mating threads are clean.
C.
Electrical Connections.
To avoid electrical shock hazards, do not connect wires when power is applied.
The DC Models Operating Voltage Range Limits are 16 – 33Vdc.
This product was only tested to its rated operating voltage range. It was not tested to
80% and 110% of these limits.
The DC units are polarity sensitive, and MAY BE DAMAGED by incorrect electrical
hookup. When connecting the DC strobe unit to the voltage supply lines, POLARITY
MUST BE OBSERVED. In addition, damage will result if the voltage operating range of
the model is exceeded.
The 224XSTHI units are provided with five leads; two red, two black and one green/
yellow. To achieve electrical supervision, connect one red (+) lead to the positive side of the
incoming power source and the other red (+) lead to the outgoing power source. Then connect one
black (-) lead to the negative side of the incoming power source and the other black (-) lead to the
negative side of the outgoing power source. If required local building codes, connect the earth
ground to the grounding screw located in the mounting hood.
III.
MAINTENANCE.
To prevent receiving an electrical shock, disconnect the fixture from the supply circuit
before opening.
High voltages are present inside the light assembly. Wait at least 5 minutes after
disconnecting power before servicing this unit.
