NOTE 1: Special order
HOUSING: The Mezzo is a die-cast aluminum
construction with a durable powder coat
finish. The lenses are constructed of a durable
UV stabilized polycarbonate with reflector for
maximum illumination.
ELECTRICAL: Available in 120/277V. The Mezzo is
CSA and wet location listed.
PHOTOCELL: Under AC power, the Mezzo is
switched on and off by a photocell. The photocell
detects when the ambient light is reduced and
turns the fixture on automatically. Operating with
a photocell makes the Mezzo energy efficient only
providing light when needed.
COLD LOCATION: The cold location option has
a battery heater pad which allows operation from
-20°C to 50°C (-4°F to 122°F) for combined AC
and Emergency versions. The AC only unit does
not require accessories to be suitable for -50°C
cold location.
LEDS: White Samsung LEDs are standard in
5000°K colour temperature. Over 75,000 hour LED
life at L70.
OPERATION: AC Only utilizes photocell technology
or a wall switch for general lighting applications.
The Mezzo is suitable for wet/damp locations
and operates in the temperature range of -50°C
to 50°C.
AC and Emergency Operation operates the
Mezzo under normal utility power and the charging
circuit maintains the battery at full capacity. The unit
is switched on/off utilizing a photocell for maximum
energy efficiency or wall switch. When AC power
fails the unit will automatically provide emergency
light. The combined AC and Emergency version
comes standard with self-diagnostics and selftest function. The Mezzo is suitable for wet/damp
locations, operation temperature range 0°C to
50°C. An alternative is the cold location option with
a battery heater pad for an operating temperature
of -20°C to 50°C.
NOTE 2: Standard on all ACEM models
MOUNTING: The Mezzo is suitable for wall mount
installation only utilizing top conduit feed or junction
box installation. Two mounting styles are included
as standard; wall junction box or top feed conduit
mount. The back of the fixture features removable
mounting knock-outs in a junction box pattern
for a clean wall mount application or a ½" NPT
threaded conduit opening is provided at the top of
the enclosure and is sealed with a closure plug.
WARRANTY: 5 year LED warranty, see website for
full warranty details.
BATTERY: The Mezzo uses an internal nickelcadmium battery that provides a minimum 90
minutes emergency duration. The battery is
protected from deep discharge by a low-voltage
battery disconnect.
AUTO-TEST: As soon as AC power is supplied
to the Mezzo, the unit will automatically initiate a
self-diagnostic test. The Mezzo will verify battery
disconnection, charger failure and transfer failure
every 5 seconds. Every month, the unit will
perform a one-minute battery discharging test.
Every six months, the unit will perform a 30 minute
battery discharging test. Once per year the unit
will perform a 90 minute battery discharging test.
A dual colour red/green LED communicates the
status of the unit.
