Federal Signal 191XL Instrucciones De Instalación Y Servicio página 4

The Model 191XL has provisions for mounting a 3/4" pipe and may be mounted in
any position. Before mounting, ensure that the mating threads are clean. To prevent
the ingress of water and dust, apply conductive sealant to the conduit threads prior
to mounting. If non-conductive sealant is used, the enclosure must be earthed via the
provided internal grounding wire/grounding screw to ensure proper grounding continu-
ity. In high-humidity environments when units are mounted dome down, condensation
may occur in the conduit system. Use properly rated conduit seals/drains to prevent
moisture from entering the fixture. Thread the fixture onto the 3/4" pipe and secure
with the set screw.
To prevent the connection from loosening, tighten the fixture to a MINIMUM torque of
5 ft-lb (6.8 N·m) after threading onto the pipe.
C. Electrical Connections for all models
Wiring must comply with the National Electrical Code or Canadian Electrical
Code and the local authority having jurisdiction.
The Model 191XL LED Beacon should be installed per the NEC or CEC,
STATE and LOCAL CODES. Alternate installation locations and/or orientations should
only be performed with the approval of the authority having jurisdiction. In addition,
the unit can be mounted using an optional ceiling mount or optional wall mount.
To avoid electrical shock hazards, do not connect wires while power is applied.
24 volt models are designed to operate on AC and DC supply voltages. The
120–240 VAC model is designed to operate 100-265 volts AC at 50/60 Hz. See
Table 1 on page 7 for electrical ratings.
The 191XL is not polarity sensitive, but MAY BE DAMAGED by incorrect
electrical hookup. Damage will result if the voltage rating of the particular
model is exceeded.
1. 120-240, 277 VAC Models
The 120-240, 277 VAC units are supplied with three 24" leads: white,
