4.4.3 Installation Guidelines
Speaker output is field-selectable between 25 and 70 volts by a jumper on the EVAX 25.
Jumper1 – 2 for 70 V and 2 – 3 for 25 V.
Connect only UL-approved speakers with a built-in line transformer.
Make sure to choose a speaker with appropriate voltage – 25 or 70 V. Select the
required power by connecting the appropriate branch in the transformer. Total power
requirements for all speakers will not exceed 25 Watts per amplifier.
Install a 2.4 K Ohm resistor at the end of the speaker output and a similar resistor in TB3
(connectors 5 – 6).
Connect the loudspeakers in the appropriate polarity to allow for line supervision.
Minimal battery size for the evacuation system is 4.5 AH 24 V for sites that do not have
an emergency generator.
24 V input to the EVAC25 will be from 24 V
DC
output from the control panel or from the
TPS34A remote power supply.
