Low-Voltage Enclosure
Low-voltage enclosures may be either
surface-mounted or flush-mounted in an
electrical closet or equipment room. Both
the number of enclosures and the types of
components within them are customized to fit
the size, lighting plan, and design of a home.
Low-voltage enclosures can be distributed
throughout the home near the rooms they are
controlling, to provide maximum flexibility during
installation of the low-voltage wiring.
21-inch Low-Voltage Enclosure
The 21-inch low-voltage enclosure provides
a compact housing for mounting up to two
HomeWorks® QS processors or up to two
system interfaces and up to five wire landing
boards (QS-WLB).
The enclosure accepts one 120 V~
(HQ-LV21-120) or 220-240 V~ (L-LV21-230)
feed to power the panel, which is self-contained
in an enclosed area, thus allowing access to only
the low-voltage connections when the enclosure
cover is removed.

Environment
Ambient operating temperature: 32 °F to 104 °F (0v°C to 40 °C)
Ambient operating humidity: 0-90% humidity, non-condensing. Indoor use
only.
Mounting
Enclosure may be surface-mounted or recess-mounted. Enclosure fits
between standard 16 in (41 cm) on-center stud framing. Mount the
enclosure so that line-voltage wiring will be at least 6 ft (1.8 m) from audio
or electronic equipment and wiring.
Mount Enclosure using one of the following methods (mounting
hardware is not pro­vid­ed):
a. S
urface Mount – Use keyholes with bolts sufficient for 100 lb (45 kg)
load, 1/4 in (M6) bolts rec­om­mend­ed.
b. R
ecess Mount – Use screws sufficient for 100 lb (45 kg) through
the corners of the enclosure. Mount enclosure fully into the stud bay,
with the back flush against the inner wall surface. Enclosure is 4.088
in (104 mm) deep past cover mounting tabs (including pedestal).
Enclosure cover dimensions are 21.5 in x 15.386 in (546 mm x
391 mm).
NOTICE: This equipment is air-cooled. Mount in a location where the
vented cover will not be blocked. 12 in (305 mm) of clearance in front of
the vents is required.
NOTICE: Power supply will hum slightly and internal relays will click while
in use. Mount in a location where such noise is acceptable.

and five wire landing boards (QS-WLB).
Examples: 1 Processor and 1 System Interface;
2 Processors; or 2 Interfaces
Line-Voltage Connections
Use copper wire only, supply conductors rated at 167 ºF (75 °C). Use
supplied wire connections to connect to corresponding power supply
harnesses.
