Tannoy CMS501BM

The CMS501 is equipped with a low insertion loss 30W line transformer easily configurable to the following settings via front baffle mounted rotary tapping switch:



70V systems: 30W / 15W / 7.5W / 3.75W / OFF & low Impedance operation

100V systems: 30W / 15W / 7.5W / OFF & low Impedance operation



Two CMS501 model versions and a separate back can are available to satisfy the vast majority of installation application requirements:



CMS501 BM (Blind Mount) - supplied with an integral back can.

CMS501 PI (Pre-Install) - supplied without a back can.

CMS501 PI Back Can (Pre-wire back can) - use with the CMS501 PI.



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.
