3.2 Connecting the Speaker
Note: All wiring should be carried out with 2-conductor stranded copper wire.
The wire calibre will usually be 18 AWG (To be specied by the designer of the
installation).
EXTERNAL CONNECTION:
The speakers are connected in parallel, in a daisy-chain conguration. The most
common way to do connections is to use twist-on connectors (not provided).
INTERNAL CONNECTION:
If regulations requires an internal connection, it is possible to seal the connectors in
the speaker enclosure:
1. Unscrew and remove the cable pass-through plate

2. Pass the power wire(s) through the wiring device. If required by the installation
design, install the additional wire(s) that have to be connected to other
speaker(s). Up to 2 additional wires can be connected to power other speakers.
3. Connect the power wire(s) to the speaker using twist-on connectors (not
provided with the speaker).
Note: Connect the red wires (+) together and black wires (-) together.
4. Secure the wires to the cable pass-through plate and insert the wires back in the
speaker enclosure. Then screw the cable pass-through plate back on the speaker
enclosure.

3.3 Securing the Speaker
Hang the speaker to the ceiling using a chain, a rod or any other appropriate device attached
to the center hook of the speaker. Then fasten the cables along the chain using tie wraps.
3.4 Setting the Tap
The VA-SPK tap can be selected using the rotary switch to adjust the output level of each
loudspeaker if required.
It is recommended to use the 0 dB position tap as a default setting with the VoiceArrest
controllers.
Older models do not have a the “dB” labelling, use the 4W @ 25V tap as a default setting
with the VoiceArrest controllers.
