CMS601 PI BACK CAN
Architectural Specifications
The Ceiling Monitor System shall consist of a 165mm (6.00") full range, point source, constant directivity Dual Concentric™ 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 prewiring 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 back can for a load bearing safety bond.
Performance of the Ceiling monitor shall meet or exceed the following criteria: The system shall have a conical coverage pattern of 111degrees (1kHz
to 6kHz). Frequency response measured on axis shall be 50Hz - 30kHz (-10dB from rated sensitivity, measured in an IEC baffle in an anechoic
chamber) with no equalization. Sensitivity shall be 91dB (1W @ 1m). Long term power handling capacity as defined in EIA-426B test shall be 80W,
recommended amplifier power 160W. Dynamic high frequency protection is provided for occasional overpowering. The nominal system impedance
shall be 8W (in low impedance setting).
The Ceiling monitor system shall be equipped with a 60Watt 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 grill covers the transducer and switch.
Two support rails and one C-Ring shall be included with the ceiling monitor system. The front face diameter shall not exceed 280mm (11.30"), overall
depth from the front of the ceiling to the top of the safety loop shall not exceed 275mm (10.90") for the blind mount variant, and 168.5mm (6.60") for
the pre install variant.
The Ceiling Monitor System shall be the.....CMS601DC.

The PI back can accepts direct
connection to installed conduit in two
ways using squeeze connectors:
1
22mm (0.87") via the clamp location at
the rear after first removing cable clamp
2
Any of the three knock-out points at the
side 19mm / 22mm / 28mm
(0.75" / 0.87" / 1.10")
