VOICE ALARM SYSTEM
Multichannel Switching VACIE
IMPACT - 4E-SW6
Small loads are a perfect match for the 4E-SW6 switching module. A simple way to distribute high power over multiple small loads. No rackbuild, No engineering!
This is efficiency !
More zones, Fewer amplifiers
The 4E-SW6 Remote Controlled Zone Expander module is a simple and cost-effective way to distribute small message packets dynamically over multiple speaker-lines.
The IMPACT concept is simple yet powerful: to provide more coverage, with a higher number of zones produced either from just one amplifier or only a few amplifiers.
When combined with 4EVAC's DCA-2.500, or other single high-power two-channel amplifier, the 4E-SW6 switching module generates simultaneous EVAC and ALERT announcements or paging messages and background music (BGM) into six switched speaker lines. By adding more 4E-SW6 switching modules it is possible to produce any multiple of six speaker lines.
BASIC SET UP Paging only
Powered by a single DCA-2.500 two channel amplifier, the 4E-SW6 switching module provides simultaneous, uninterrupted paging and BMG for six manageable speaker lines. A third internal channel is used by the surveillance tone generator to continuously check the integrity of the cable and detects any faults. The third internal channel can also be addressed if the speaker lines need to be silenced.
The cable integrity detection process works by the 4E-SW6 generating a separate AC carrier for each individual line. This is received by a simple, cost effective end-of-line module (EOL), creating a cable monitoring system that checks for short- and open-line faults.
The 4E-SW6 switching module is easy to install. It comes in a quick-snap DIN- rail housing and is supplied with speaker line connectors that directly accept external field cabling up to 2.5 mm2/12 AWG.
Each speaker line is able to support loads from as small as 1W to as big as 400 W. This ‘dynamic-load-distribution’ makes IMPACT the most flexible and versatile VACIE system in the industry and optimises the use of all modules on the network.
