Installation Manual: EVAX EVX-ATM Audio Transponder Module
NOTICE TO THE INSTALLER
This manual provides an overview and the installation instructions for the EVAX EVX-ATM Audio Transponder Module. 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 devices. Refer to the installation manuals for proper system operation.
Description
The EVX-ATM provides a method of interfacing audio either into the evac system or from the evac system into an external paging
system. It has several methods of accomplishing this and is eld selectable for itsmodes. It is capable of being activated by either
contact closure or signal presence by use of a VOX, Voice Activation Circuit. Its input may be Balanced Line, 1 Vrms into 600 Ohms, 25
Vrms or 70 Vrms.
The input and output signals are isolated so systems will not experience ground loop problems.
Mounting: EVX-ATM mounts into standard 3” snaptrack. The board also has mounting holes at the corners for stand-off mounts where
required.
