EVAX 25, 50, 150, 200, 100 Installation Manual
Installation Manual: EVAX 25/50/100/150/200 Voice Evacuation System
NOTICE TO THE INSTALLER
This manual provides an overview and the installation instructions for the EVAX 25/50/100/150/200 Voice Evacuation Interface System.
All terminals are power limited and should be wired in accordance with the requirements of NFPA 70 (NEC), NFPA 101 (Life Safety
Code) and NFPA 72 (National Fire Alarm Code). Failure to follow the wiring diagrams in the following pages will cause the system to not
operate as intended. For further information, refer to the control panel installation instructions.
The module shall only be installed with listed control panels. Refer to the control panel installation manual for proper system operation.
1. Description
The EVAX 25/50/100/150/200 is a self contained amplier, 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 25/50/100. The EVAX 25/50/100 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 25/50/100 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 circuit.
The EVAX 25/50/100 is designed to be powered from 120 VAC at 60 Hz. The EVAX 25 will provide 25W to the speaker circuit. The
EVAX 50 will provide 50W. The EVAX 100 will provide 100W. Speakers may be 25 or 70 Vrms (jumper selected, 25V is factory set).
Note: Models may be supplied with transformers wired for 240 VAC for those regions where this is required. Please refer to Ratings
section for Primary Power differences.
MODELS: The EVX-25/50/100 are complete Voice Evacuation Modules, EVX-25E/50E/100E are complete modules with built-in tone
generators capable of operating as a stand-alone Voice Evacuation Systems with only tone and microphone amplication. They are not
equipped with power transformers or cabinets. The EVAX 25/25EM/50/50EM/100/100EM/150/150EM/200/200EM are complete Voice
Evacuation Panels. The EVX-50E/100E are capable of operating as slave ampliers when connected to the EVX-100 which supplies
source audio to the slaves. Different Model numbers are derived from the amplier sizes used together: These multiple amplier
congurations are factory setup and pre-wired. When using any EVX-25E/50E/100E refer to installation instructions 5403672.
EVAX 150 contains one (1) EVX-100, one (1) EVX-50E and two (2) speaker circuits
EVAX 200 contains one (1) EVX-100, one (1) EVX-100E and two (2) speaker circuits
EVAX 150E contains one (1) EVX-100E, one (1) EVX-50E and two (2) speaker circuits
EVAX 200E contains two (2) EVX-100E and two (2) speaker circuits.
The EVAX 100 / 200 are tested compliant with UL 464 520 Hz Low Frequency Signal for Sleeping Areas with the following:
Potter Signal Series: FASPKR, SPKSTR Gentex Series: SSPKCLP, SSPK24WLP System Sensor Series: SPCW, SPCR, SPR and
SPW
2. Installation and Wiring
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 modications to the enclosure, be certain that they will not interfere with assemblies or batteries
Install equipment adjacent to FACP or FACP Annunciator to ensure proper reporting and display of system Fault conditions.
1. Connect speaker lines to TB1 - 5(+) & 6(-), observe polarity and ensure all speakers are connected likewise. For Class "A" (Style
"Z")the returns are TB1 - 7(-) & 8(+).
2. Ensure that the microphone is attached to connector P2. If Microphone is not installed ensure that switch SN1 - 8 is in the OFF
position.
3. Attach the appropriate EOLR for the FACP to TB3 - 3 & 4 and TB3 - 5 & 6. The TB3 term 5 & 6 value must be placed at the end
of the speaker line as well. You must use EOLR value as specied in the FACP Manufacturer’s installation instructions for the
indicating appliance circuit. All accessory cards such as the EVX-ZM, EVX-SL8, EVX-IL8 or EVX-OL8 must be mounted within the
same cabinet or if mounted in a separate cabinet, be in the same room with all wiring run in conduit within 20 feet.

4. Connect FACP signaling circuit to TB1 - 3(+) & 4(-), Alarm Polarity (alarm polarity is shown).
5. Connect 120 VAC, 60 Hz, power to the white Terminal Block on the left side of the cabinet. Terminals are Hot / Neutral /
Ground, from left to right. Pre-wired to unit and chassis on opposite side of Terminal Block. Wire colors Black / White / Green
from left to right. Max. 10 AWG
6. Once power is on to the unit, connect battery wiring harness, Red (+) / Black (-). Observe polarity. Minimum battery size is
24V 7Ah. Maximum size to house in cabinet is 12Ah, battery box required beyond 12Ah (use two (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, ensure that switch SN1 - 7 is in the OFF position. NOTE: Wiring for batteries is Non Power-Limited. Care
must be taken to ensure 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, it must be in the same room with a 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 25 / EVAX 50 / EVAX 100 is
fully operational and all circuits are nominal.

OPTIONS:

These terminals provide a max. 200 mA of regulated 24VDC power for auxiliary functions. Do not exceed 200 mA load combined
on these terminals. For connection to Listed General Signal devices only (Non-Fire Protective Signaling applications). Terminal 4
activation is programmed in the system conguration. Standard conguration is programmed for TB2-4 to go active +24VDC under
these conditions: Aux Signal Active, Aux Audio Enable and Bell Circuit Active.
CONNECTION OF AN AUX AUDIO SOURCE - TB2-1 & 2
An aux audio source from additional paging equipment may be connected to the EVAX 25 / 50 / 100 to augment an existing paging
system. It is not intended for continuous signal input, but may be used for paging applications. For such an operation the Aux Audio
Enable input, TB2-6, must be powered from Int V+, TB2-9. This is to ensure 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 signaling 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 A and B must be removed from J1 if a circuit is to be connected in this manner. See Optional
Supervisory Circuit Application (Wiring Diagram 2) for connection detail.
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 modulate with the audio level.
Default Factory Alarm Sequence settings: (Alarm Tone - 2 cycles Temporal Whoop, Message On - 3 Repeats)
Alarm Tone / Digital Message plays / Alarm Tone / Digital Message plays / Alarm Tone / Digital Message plays / unit reverts to
Alarm Tone 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 repeat. 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. Under a fault condition, the Yellow LED will remain on. The Green LED will ash. The number of ashes display a code
depending on the specic 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. During a ground fault condition, Yellow LED 4 will
illuminate.
