EVAX 25 / EVAX 50 / EVAX 100 / EVAX 150 / EVAX 200
VOICE EVACUATION INTERFACE SYSTEM
INSTALLATION INSTRUCTIONS
The EVAX 25 / EVAX 50 / 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 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).
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 amplification. They are not equipped with power transformers or cabinets. The EVAX 25 / 25E / 50 / 50E / 100 / 100E / 150 / 150E / 200 / 200E are complete Voice Evacuation Panels. The EVX-50E / 100E are capable of operating as slave amplifiers when connected to the EVX-100 / 100E, which supplies source audio to the slaves. Different Model numbers are derived from the amplifier sizes used together: These multiple amplifier configurations are factory setup and pre-wired. When using any EVX 25E / 50E / 100E refer to installation instructions P/N B-5002 Rev. E.

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
Install equipment adjacent to FACP or FACP Annunciator to insure proper reporting and display of system Fault conditions..
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 . Insure that the microphone is attached to connector P2. If Microphone is not installed insure that switch SN2 - 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 specified in the FACP manufactures installation instructions for the indicating appliance circuit. Note: if your system includes one or more EVX-4Z zone splitters, the FACP EOLR is relocated. See EVX-4Z install instructions P/N 1-5022.
4.Connect FACP signaling circuit to TB1 - 3(+) & 4(-), Alarm Polarity (alarm polarity is shown).
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 on to the unit, connect battery wiring harness, Red (+) / Black (-). Observe polarity. Minimum battery size is 24V 7Ah. Maximum battery size is 18Ah on EVAX 25 / EVAX 50 and 24Ah on EVAX 100. (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, 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 25 / EVAX 50 / EVAX 100 is fully operational and all circuits are nominal.

OPTIONS:
AUX +24VDC OUTPUT - TB2-4, 8, 9 & 10
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 U6 EPROM chip. Standard chips are programmed for TB2-4 to go active +24VDC under these conditions: Aux Signal Active, Aux Audio Enable, Bell Circuit Active, RSI Active. Reprogramming of these functions must be done at the factory and require replacing EPROM U6.
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 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 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 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. During a ground fault condition, Yellow LED 4 will illuminate.

*Battery input current measurements are determined by test conditions. Two values are shown. First value reflects the unit with a full speaker load and no auxiliary load. Second value reflects the unit with a full speaker load and a full auxiliary load of 0.5A in Standby and 0.75A in Alarm. Your actual load will vary depending on which and how many auxiliary devices, ie...Zone Splitter, Remote Mic, Relays,...etc., are used. Insure that any current draw from an aux device is added into your final battery calculation.
**Input current measurements are determined by test conditions under UL 1711. Sine represents measurements made while the unit produces a continuous non-distorted sine wave of 1 KHz into the rated load of 25 / 50 / 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.
TESTING
Per NFPA 72 Chapter 7, 100% system test is required, at a minimum, annually. Additional testing may be required by the Local Jurisdiction.
