Architectural Specifications
The Ceiling Monitor System shall consist of a 200mm (8.00") full range, point source, constant directivity Dual ConcentricTM transducer and passive frequency
dividing network mounted in a vented, injection moulded, paintable front baffle in UL94V-0 ABS material.
The back can in both PI (pre-install) & BM (blind-mount variants) shall be constructed of zinc plated steel. A recessed termination box shall be integrated with
the back can, a removable locking connector with screw terminals for secure wire termination with "loop through" facility shall be provided. Strain relief will be
provided by a clamping mechanism for use with plenum rated cable or conduit.
For pre-wiring the PI (pre-install) back can is provided with conduit knockouts (19mm/22mm/28mm, 0.75"/0.87"/1.14"). A safety ring is located on the rear of
the backcan for a load bearing safety bond.
Performance of the Ceiling Monitor System shall meet or exceed the following criteria: The system shall have a conical coverage pattern of 100 degrees
(1kHz to 6kHz). Frequency response measured on axis shall be 40 Hz - 35kHz (-10dB from rated sensitivity, measured in an IEC baffle in an anechoic chamber)
with no equalization. Sensitivity shall be 92dB (1W @ 1m). Long term power handling capacity as defined in EIA-426B test shall be 90W, recommended
amplifier power 180W. Dynamic high frequency protection is provided for occasional overpowering. The nominal system impedance shall be 8 Ohms (in low
impedance setting).
The Ceiling Monitor System shall be equipped with a 60W high performance line transformer for use in 70.7 or 100 Volt distributed audio systems with 60,
30, 15, 7.5* Watt taps available. An easily accessible rotary switch located on the front baffle shall be available for selecting transformer and low impedance
settings. A weather resistant perforated steel grille covers the transducer and switch.
Two support rails and one C-Ring shall be included with the ceiling monitor system.
