TMP INSTALLATION
TMP
provides a Stereo Line Level output and a 3.5mm Stereo to RCA Audio
cable is provided for connection to an Amplifier.
A 9VAC Power Adaptor is supplied to provide power for
TMP
The separate Amplifier is then used to power the required number of
speakers (usually 100V paging/music speakers).
The amplifier used should have a power rating (W), greater than the sum of
the tapping setting of all speakers connected to it.
If higher volume is required on one or more speakers, then you may increase
the tapping to a higher W setting.
SPEAKER CABLE
You should use figure 8 speaker cable with a power rating suitable for the
amplifier which you plan to use.
You can use ‘Light Duty’, such as 14/0.14 for amplifiers with an output of
50W RMS or less.
For amplifiers with a power rating of greater than this, you should use ‘Heavy
Duty‘ 24/0.20.
100V SPEAKERS
TMP
units can also operate with 100V Background Music/ Paging speakers,
providing the amplifier has a 100V amplified output, or where there is a
suitable external 100V transformer in series before the first speaker.
100V Background Music/ Paging speakers can be Ceiling Mounted or Wall
Mounted. 100V Speakers are designed to connect in Parallel fashion, as
indicated on the Installation Diagram.
This means that the amplifier connects to one speaker, direct into the
appropriate tapping of the 100V speaker transformer. The next speaker
connects from that same point, and so on to the last speaker, in a ‘daisy
chain’ type fashion.
