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.
