CMS801 DC
Product Description
The Tannoy CMS801 DC is a full bandwidth; high power and high sensitivity ceiling monitor system. The
200mm (8.00") Tannoy Dual Concentric
pulp mid bass cone and a 25mm (1.00") ferrofluid cooled, titanium dome HF unit with neodymium magnet
system. The driver and passive frequency dividing network are mounted in a vented, injection moulded,
paintable front baffle manufactured from UV/weather resistant UL94V-0 ABS material.
The mid-bass and tweeter sections of the Tannoy Dual Concentric
aligned to a true point source; ensuring a wide and controlled dispersion for optimum coverage; this while
avoiding the massive loss of energy, in the vertical plane at the crossover frequency, inherent in two-way
discreet designs. This high power and high sensitivity design, with extended frequency response and very
low distortion, is equipped with dynamic high frequency protection.
This compact unit is specifically designed for applications requiring the combination of premium sonic quality
for music and speech reinforcement and exceptional reliability and intelligibility.
Two CMS801 DC model versions and a separate back can are available to satisfy the vast majority of
installation application requirements:
CMS801 DC BM (Blind Mount) - supplied with an integral back can.
CMS801 DC PI (Pre-Install) - supplied without a back can.
CMS801 PI Back Can (Pre-wire back can) - use with the CMS801 DC PI.
The CMS801 DC BM model is equipped with a low insertion loss 60W line transformer mounted within the
back can. This is easily configurable to the following settings via front baffle mounted rotary tapping switch:
70V systems: 60W / 30W / 15W / 7.5W / OFF & low Impedance operation
100V systems: 60W / 30W / 15W / OFF & low Impedance operation
The CMS801 DC PI is supplied without a transformer. If the product is to be used without a back can a 60W
line transformer (7600 1658) is available as an optional accessory for easy connection to the baffle mounted
control switch circuit. Installing the transformer in this manner (flying) requires installation in accordance
with local building regulations.
NOTE: For optimum performance and full compliance with safety ratings Tannoy recommends using the
CMS801 PI back can (8001 4570) accessory option in which the transformer is pre-fitted.
The zinc plated steel back cans have an integrated, recessed termination box. The removable locking
connector has screw terminals for secure wire termination and "loop through" facility. Strain relief is provided
by a clamping mechanism for use with plenum rated cable or conduit.
Spring loaded self-aligning clamps make for quick and easy installation, while all models are also supplied
with two tile support rails and one C-ring included in the package.
A plaster (mud) ring is available as an optional accessory.

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")
