EVAX 25 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 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).
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 amplification. 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 amplifiers when connected to the EVX-100 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 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 modifications 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 specified 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.
