AMPLIFIERLOCATION
For most applications the amplifier should be located inside the entrance
panel housing. Some entrance panels have provision for mounting the
amplifieronthebackofthepanel.Keepamplifierawayfromtransformers
and other electrical equipment. Avoid temperature extremes. Normal
operating temperature is 0°C - 30°C. If it is necessary to run additional
wire from the panel to the amplifier, use shielded wire to connect the
microphone.

utilize a speaker, electrostatic microphone, as well as a diode connected
to each push button. If reusing an existing panel manufactured by others,
contact our technical department for installation details.
