Telefire
ADR-3000 – System Introduction
Revision 1.10 4 November 2004
4.3 EPI-3000 Electromagnetic and Surge Protection Interface Module
Industrial installations may have strong electromagnetic interference. In order to isolate
the SLC loops and 24 V
DC
outputs from electromagnetic interference install Telefire's
EPI-3000 Electromagnetic and Surge Protection Interface Module. One EPI-3000
module will isolate all four loops, and both 24 V
DC
outputs (24V_A and 24V_B) of a
single control panel.

4.4 Evacuation System
4.4.1 Introduction
The EVAX 25 is an evacuation system that can be integrated with the ADR-3000 fire
alarm system.
The system is powered and supervised by the analog addressable ADR-3000 and
allows announcing standard warning sounds and messages in the protected premises
according to the logic of the AAM (Advanced Activation Matrix) of the ADR-3000.
The unit allows announcing warning and general messages throughout the site or only to
specific areas.
The system is modular and may be connected via multiple amplifiers to as many as
2,000 speakers installed in various zones with command and control performed by the
fire alarm system.
4.4.2 Features
• UL approved
• Activation and supervision through ADR-8XX input- and output modules
• Speaker connection can be either Class A or Class B
