EXPANDER

INSTALLATION INSTRUCTIONS

The EVX-25E/ EVX-50E / EVX-100E is a self contained amplifier, tone generator, power supply and supervisory interface. It is designed to be used in conjunction with the EVAX 25/

50 /100 to provide additional speaker output power. It may also be used stand-alone in conjunction with a Fire Alarm Control Panel to provide voice evacuation where an automatic message is not desired.

Installation and operation is identical to the EVAX 25/ 50 /100 (see Installation Instructions P/N 1-5001 Rev. D). With the exception that no digital message is present. When used in conjunction with the EVAX 25/ 50/100 the Expander will act as a slave reproducing the tone and message generated by the master. When used as a stand-alone, the Expander will connect to the FACP exactly as the EVAX 25/ 50/100 does to provide automatic tone in alarm and voice override capability.

All terminal designations and volume controls are identical to the EVAX 25/ 50/ 100. One exception is that on the Expander SN1 determines Tone, Master/Slave, Battery and

Microphone supervision. There is no SN2.
