EVAX EVX-ZM User manual

Installation Manual: EVAX EVX-ZM Zone Splitter
NOTICE TO THE INSTALLER
This manual provides an overview and the installation instructions for the EVAX EVX-ZM Zone Splitter. 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 control panels. Refer to the control panel installation manual for proper system operation.
Description
The EVX-ZM Zone Splitter Module is intended for use with the EVAX 25/50/100. Its purpose is to enable the output of the EVAX
25/50/100 to be split into multiple circuits for audio power distribution. The modules accept input from the EVAX 25/50/100 speaker
output and utilize output relays to distribute the power to separate circuits. The modules may be cascaded to increase the number of
circuits. The modules provide supervision of the individual circuits for either open or short conditions. Indicator LEDs display active or
fault condition for the individual circuits. Fault condition is reported to the EVAX 25/50/100 via the I2C communication port. The EVX-ZM
may also be used with legacy EVAX 25/50/100 models, but supervision must now employ TB2 Terminals 10-11 as a supervisory input.
Consult factory for connection details.
If Manual control of the circuits is required an EVX-SL8 must be employed. Zones may then be selected manually by switches or
through pull-down inputs. In the event of an alarm condition, module defaults to an All-Call. All-Call feature may only be overridden if
accompanying panel has zone control features
Installation and Operation
Install equipment in a clean, dry environment, avoid installation where equipment could be subjected to vibration. Remove electronic
assemblies from the enclosure prior to any drilling or punching of the enclosure. Where possible, make all cable entries from the rear or
sides. Before making any modications to the enclosure, be certain that they will not interfere with assemblies or batteries.
In normal standby the EVX-ZM will supervise each speaker zone wire loop. The EVX-ZM will provide 4 Class B (Style Y) or 2 Class A
(Style Z) speaker circuits. This is eld selectable via SW1. Upon an open or short condition the Amber LED for that zone will light. This
Fault will report through the EVAX 25/50/100 to the supervising FACP.
If manual Zone selection is employed, select the corresponding EVX-SL8 switch. It’s Red LED will light, and the EVX-ZM output relay
activation will be enabled. On activation of the PTT signal from the EVAX 25/50/100, the output relay will connect the zone to the EVAX
25/50/100 speaker output.
In an Alarm condition the EVX-ZM defaults to an All-Call. On activation of the EVAX 25/50/100 V+ Alarm output, all zones are
automatically selected, enabling evac tone and message to play. Modules will have eld selectable option for alarm zone activation only
if the FACP has the ability to provide separate pull-down inputs.
Speaker output may be 25 or 70 Vrms. This is eld selectable by SW1-2. Output circuits are limited to 50W per zone at 70 Vrms and
40W at 25 Vrms. Total speaker load combined is not to exceed output rating of the EVAX 25/50/100 driving the Zone Module. Upon a
short condition, the shorted zone will open excluding that zone from output and enable the other zones to continue operating. Speaker
circuits must be terminated with a 10K EOLR device. The end of line value is not adjustable or programmable. Speaker circuits will
indicate a Fault if the circuit impedance falls to 5K or increases to 15K Ohms.
