EVAX 100
VOICE EVACUATION INTERFACE SYSTEM
INSTALLATION INSTRUCTIONS
GENERAL
The EVAX 100 is a self contained amplifier, tone generator, digital message repeater and supervisory
interface. It is designed to be used in conjunction with a UL listed Fire Alarm Control Panel (FACP) to
provide a Listed Voice Evacuation Alarm System.
The FACP provides all initiating circuitry and a signaling circuit to the EVAX 100. The EVAX 100
provides its own internal supervision as well as supervision for its speaker lines. Any fault is reported
back to the FACP. In normal standby the supervisory circuit from the panel is connected to a matching
EOLR. Should the EVAX 100 suffer an internal failure or should there be any fault on the speaker line, a
contact would open and the FACP would report it as an open fault for that FACP circuit.
The EVAX 100 is designed to be powered from 120 VAC at 60 Hz. It will provide 100W to the speaker
circuit. Speakers may be 25 or 70 VRMS (jumper selectable, 25 V is factory set).
MODELS
The EVX-100 is a complete Voice Evacuation Module. It is not equipped with a power transformer
or a cabinet.
The EVAX 100 is a complete Voice Evacuation Panel. It is equipped with a power transformer and
a cabinet.
The EVX-100E is a complete slave amplifier with built-in tone generator. It is capable of operating as
a slave amplifier when connected to the EVX-100, which supplies source audio to the slave. It is also
capable of operating as a stand-alone Voice Evacuation System with only tone and microphone
amplification.
Different Model numbers are derived from the amplifier sizes used together: These multiple amplifier
configurations are Factory setup and pre-wired. The following are in their own cabinet with power
transformers. They are complete Panels.

INSTALLATION
Installer must insure that all wiring and devices installed in system meet the following standards:
National Electrical Code (NFPA 70)
NFPA Standard 72
Life Safety Code (NFPA 101)
Install equipment in a clean, dry environment. Avoid installation where equipment could be subjected to
vibration. Remove electronic assemblies from the enclosure prior to any drilling or punching of the
enclosure. Where possible, make all cable entries from the rear or sides. Before making any
modifications to the enclosure, be certain that they will not interfere with assemblies or batteries.

WIRING (Refer to wiring and terminal designation diagrams)
1. Connect speaker lines to TB1 - 5(+) & 6(-). Observe polarity and insure all speakers are connected
likewise. For Class "A" (Style "Z"), the returns are TB1 - 7(-) & 8(+).
2. Connect Speaker Matching EOLR to TB3 - 5 & 6. This value must be placed at the end of the speaker
line as well.
3. Insure that the microphone is attached to connector P2. If the Microphone is not installed, insure that
switch SN2 - 8 is in the OFF position.
4. Connect FACP signaling circuit to TB1 - 3(+) & 4(-), Alarm Polarity. Attach the appropriate EOLR for the
FACP to TB3 - 3 & 4 You must use EOLR value as specified in the FACP manufactures installation
instructions for the initiating appliance circuit.
5. Connect 120 VAC, 60 Hz, power to the black and white pigtail leads from transformer primary.
Secure ground lead to grounding stud in cabinet.
6. Once power is applied to the unit, connect battery wiring harness, Red (+) / Black (-).Observe polarity.
Minimum battery size is 24V 7AHr. Maximum battery size is 24AHr. (Use 2 12V batteries connected in
series. See typical installation diagram). If the unit does not have its own batteries and relies on an external
power supply with battery back-up, insure that switch SN2 - 7 is in the OFF position. NOTE: Wiring for
batteries is Non Power-Limited. Care must be taken to insure that all Power-Limited wiring maintain a
minimum spacing of ¼" from any Non Power-Limited wiring. If batteries must be located in separate
enclosure, provide separate conduit run for battery wiring only.
Once all power and circuits are connected, the Green LED will remain on to indicate that the
EVAX 100 is fully operational and all circuits are nominal.
OPERATION
In normal standby the Green LED will remain on.
In alarm condition the Red LED will remain on as long as the unit is in alarm. Green LED will also
remain on.
Alarm Sequence Factory settings:
Alarm Tone - Alarm Signal 5 seconds / Digital Message plays / Alarm Signal 5 seconds / Digital
Message plays / Alarm Signal 5 seconds / Digital Message plays / unit reverts to Alarm Signal until
alarm condition is cleared. If the Mic is keyed, it will override both the tone and the message so a direct
broadcast may be made. If this occurs during the initial sequence the digital message will be reset and
will not play.
When the Mic is keyed or when the message is played, the Green LED will dim. The intensity of the
Green LED will vary with the level of the broadcast audio. This is true in Alarm condition as well.
Under a fault condition, the Yellow LED will remain on. The Green LED will flash. The number of
flashes display a code depending on the specific type of fault. When there is a fault condition, the contact
connecting the FACP signal circuit to the EOLR will open indicating the fault to the panel which will
provide annunciation.

BATTERIES
The EVAX 100 contains a built-in battery charging circuit and supervision circuit. The EVAX 100 has
a maximum available charging current of 1A. For 24V batteries, this relates to a maximum battery size
of 24Ahr. The minimum recommended battery size 7Ahr.
OPTIONS
Refer to Terminal Designations diagram.
AUX +24VDC OUTPUT - TB2-8, 9 & 10
These terminals provide a maximum .5A of regulated 24VDC power for auxiliary functions. Do not
exceed .5A load combined on these terminals. This connection may be used for auxiliary relay control
control contacts which may be made or broken on the advent of an alarm condition.
CONNECTION OF AN AUX AUDIO SOURCE - TB2-1 & 2
An aux audio source from additional paging equipment may be connected to the EVAX 100 to augment
an existing paging system. It is not intended for continuous signal input, but may be used for paging
applications. For such operation, the Aux Audio Enable input ( TB2-6) must be powered from Int V+
(TB2-9). This is to insure that in the event of an alarm, the aux audio will not override the evacuation
signal. See Wiring Diagram 5 for connection detail.
OPTIONAL SUPERVISORY CIRCUIT - TB3-1 & 2
In place of normal supervision via the signalling circuit, an alternate method may be employed using any
supervisory circuit from the FACP. Connection would be made to Terminal Block 3, Ter. 1 and 2. This
would provide a normally closed connection to the EOLR on Ter. 3 and 4. The relay contact in the circuit
will open upon any trouble condition and report an open circuit trouble to the FACP. NOTE: Jumper
shorting blocks 1 and 2 must be removed from J1 if a circuit is to be connected in this manner. See
Wiring Diagram 2 for connection detail.

*Input current measurements are determined by test conditions under UL 1711. Sine represents measurements made
while unit produces a continuous non-distorted sine wave of 1 Khz into the rated load of 100W at rated output
voltage. Alarm is the average current the unit experiences delivering an alarm signal, Temporal Whoop, to the rated
load. Standby is the current draw of the unit with all normal power on and aux. terminals fully loaded. Battery
Standby is current draw from the batteries on loss of power and otherwise normal standby.

INSTALLATION INSTRUCTIONS
The 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 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 are identical to the EVAX 100 with the exception that no digital message is
present. When used in conjunction with the EVAX 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 100 does, to provide automatic tone in alarm and voice
override capability with the microphone.
All terminal designations and volume controls are identical to the EVAX 100. One exception is that on
the Expander SN1 determines Tone, Master/Slave, Battery and Mic. There is no SN2.
Factory defaults for SN1 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 Batteries connected (OFF = No Batteries)
8 = OFF No Mic (ON = Mic connected)
Expander as Master / Stand-Alone
1 = OFF Temporal Whoop Signal
2 = OFF
3 = OFF
4 = OFF
5 = OFF
6 = ON Master setting
7 = ON Batteries connected (OFF = No Batteries)
8 = ON Mic connected
