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.
Bezel diameter 325mm (12.80")
BM Front of ceiling to rear of back can 310.50mm (12.22"), Front of ceiling to top of safety loop 327.80mm (12.90")
PI Front of ceiling surface to rear of speaker unit 118.70mm (4.67"), Front of accessory back can bezel to top of safety loop 168.50mm (6.63")
The Ceiling Monitor System shall be the...CMS801 DC.
