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.
