EWCIE Technical Manual
10.5 Multiple Housing/Battery Box requirement
When there is a requirement for the EvacU EWCIE to be housed in more than one cabinet due to
space limitations it is recommended that the Ampac battery box is used to accommodate the
required system batteries.
In these situations it is imperative that the battery box is installed directly below or adjacent to the
EvacU EWCIE cabinet to maintain AS4428:16 mechanical design compliance.
10.6 Connecting to OEM equipment
OEM equipment should be connected to the Standalone Evacu by interfacing to the amplifier’s
Digital Inputs and Relay outputs.
The recommendation for connecting to the inputs is via volt free contacts and switching the
Standalone Evacu’s +24V required for input 1 and the 0V (Com) required for inputs 2,3 and 4 as per
the image below:

For all amplifier Inputs, Relays and Dip switch settings refer to the applicable tables in section five.
