Wall Mount Enclosures
Q2050 Series
DESCRIPTION
The Q2050 Wall Mount Enclosure Series using R8471
controller technology are designed for easy field installation of a comprehensive gas detection system. These
enclosures are designed for a NEMA 4X rating and are
available in two sizes. They are pre-assembled with any
combination of up to six single channel gas controllers
mounted within, including those for combustible, hydrogen sulfide, carbon monoxide, chlorine and oxygen gas
detection. The enclosures can be supplied with a
power supply that is pre-wired to the controller input
power connections, or controller input power (+24 vdc)
can be brought in from outside the enclosure and wired
directly to the controllers.
The enclosures are made of fiberglass with a door that
features a full view polycarbonate window and a stainless steel hinge and twist locks. Wiring access holes
can be drilled at the time of installation or the enclosure
can be provided with pre-drilled holes with watertight
conduit fittings installed, as specified.
STANDARD FEATURES
ENCLOSURE
• One to six controllers (any combination)
Installation of the Q2050 Series Enclosures with gas controllers involves mounting the enclosure, drilling a wiring
access hole (if not custom drilled), installing appropriate
hardware, then proceeding with the usual gas detection
system wiring (providing input power, connecting the
gas sensors to the controller, and connecting annunciating/indicating/alarm response devices to the controller
outputs). Two enclosure sizes are available:
• Controllers mount on a removable subpanel
• Designed for NEMA 4X rating
• Fiberglass box with full view polycarbonate window
• Stainless steel twist locks and hinge
• Easy access wiring terminal strip for each controller
• Offered with or without self-contained power supply

OPTIONS
• Horn (100 db at 10 feet, 120 vac, 50/60 Hz, weatherproof, mounted separately from enclosure)
INPUT VOLTAGES—
Models with no power supply:
External +24 volt dc source must be provided to power
the controllers (range of 18 to 32 volts dc acceptable).
Maximum ripple should not exceed 5 volts peak-to-peak.
The sum of dc plus ripple must be ≥18 vdc and ≤ 32 vdc.
• Strobe (blue, 25 watt, 90 flashes per minute, 120
vac, 50/60 Hz, NEMA 3R rating, mounted separately
from enclosure)
• External reset switch installed on enclosure
Models with power supply provided:
— Standard model requires 120 volts ac (range of 105
to 132 volts ac acceptable); 47 to 63 Hz, provides
up to 3.6 amperes at 24 volts dc and 77°F (25°C).
— Optional models available that accept 100, 220, or
230/240 volts ac (+10%, –13%); 47 to 63 Hz.
Specify input voltage when ordering.
• 3/4 inch watertight conduit fitting for access to field
wiring
• Fused field wiring terminal strip
• Heaters
• For special order needs, contact factory.
