Bosch EVX-50E, EVX-25E, EVX-100E Installation Manual
EVX-25E / EVX-50E / EVX-100E
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.
Factory defaults are:
Expander as Slave
1 = OFF Temporal Whoop Signal
2 = OFF
3 = OFF
4 = OFF
5 = OFF
6 = OFF Slave (ON = Master setting)
7 = ON Battery connected (OFF = No Batteries)
8 = OFF No Mic (ON = Mic connected)
Expander as Master / Stand-Alone
SN1 Tone Selection
