ZT-MNS-70V-XFMR
70 Volt Transfer Kit
The ZT-MNS-70V-XFMR (70 Volt Output) Module converts the MNS-
100’s 25VRMS speaker output to
70VRMS. Use of 70VRMS for longer wire runs, results in less loss of output level.
The small enclosure is mounted near the MNS-100 cabinet.
Five conductors are used for the connections of the Module to the MNS-100 main circuit board.
Full output power and active supervision of the speaker circuits are maintained using the specifically
designed circuitry in the MNS-70V-Xfmr
.

The ZT-MNS-70V-XFMR Module mounts to the
wall near the ZT-MNS-100BAS, or APB) cabinet.
There are no user controls inside the cabinet; it
can be mounted away from the MNS-100,
but must be in the same room, and connected with
conduit to the MNS-100.
There are four mounting holes in the cabinet, with the top two key-holed. Use fasteners and hardware of
the appropriate size to support the enclosure and the module’s 6 pound weight.
There are four knock-outs in the enclosure for wiring access. The bottom or sides are recommended.
It is intended for indoor, dry locations only, with an environment of 32 to 120 degrees F, and 90% humidity non-
condensing maximum. Care must be taken to avoid water infiltration or condensation. Do not mount directly on an
exterior wall that could enhance condensation, use of a back board or rails is recommended.
