Installation Manual: EVAX EVX-25E/50E/100E Expander

NOTICE TO THE INSTALLER

This manual provides an overview and the installation instructions for the EVAX EVX-25E/50E/100E Expander
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 EVX-25E/EVX-50E/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 25/50/100 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 is identical to the EVAX 25/50/100 (see 5403670 Installation Guide) with the exception that no digital
message is present. When used in conjunction with the EVAX 25/50/100 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 25/50/100
does to provide automatic tone in alarm and voice override capability.
All terminal designations and volume controls are identical to the EVAX 25/50/100. One exception is that on the Expander SN1
determines Tone, Master/Slave, Battery and Microphone supervision. There is no SN2.

2. Installation, Wiring and Programming

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.
Ensure all power is off before making any wire connections. The guides below indicate how to change the settings on the Expander
module using dipswitches built into the device. The diagrams on the following page indicate proper wiring for the EVX-25E/EVX-50E/
EVX-100E as well as the location of the dipswitches, labeled as SN1.
