Hochiki EVX-ATM

EVX ATM Transponder Module EVX ATM provides a method of interfacing audio either into the evac or from the Evac system into an external paging system has several methods of accomplishing this and is field selectable for its is capable of being activated by either contact closure or signal by use of a VOX Voice Activation Circuit Line 1 Vrms into 600 Ohms 25 Vrms or 70 Vrms input may be input and output signals are isolated so systems will not experience loop problems EVX ATM mounts into standard 3 snaptrack The board also mounting holes at the corners for stand off mounts where required 1 Board 1 Push To Talk 2 V 24V DC 0.10A Y Q R 5 M B C D PTT Function Path Input Contact Input 3 ALARM 4 SIG 5 AUX PTT 6 Signal 7 Aux Audio PreAmp 1 2 Audio input Line 1V 600 Ohm 25 70 1 2 N O Dry Contact 3 4 Bal Line output 24 VDC Standby Active 3 x 3 holes 0.160 dia 0.25 centered corners 1 5028 Rev D 1 of 4 2 Audio into the Evax System dry relay contact provides activation EVX 25 Settings R C 5 1V 25V 70V Y V wiring connections wire clamp screw 14 18 AWG wire clamp screw 12 18 AWG wire entry terminal 18 26 AWG gauge determined by circuit load Y Q R 5 M B C D 70V selected at J4 600 Ohm supplied dry relay contact activate aux audio 3 Audio input w VOX signal input provides activation EVX 25 Settings P C 1 1V 25V 70V X V wiring connections wire clamp screw 14 18 AWG wire clamp screw 12 18 AWG wire entry terminal 18 26 AWG gauge determined by circuit load Q R 5 M B C D 70V selected at J4 600 Ohm Y X jumper selects VOX activation Signal alone enables input 1 5028 Rev D 2 of 4 wiring connections wire clamp screw 14 18 AWG wire clamp screw 12 18 AWG wire entry terminal 18 26 AWG gauge determined by circuit load Settings B M 1V X 4 System driving External Audio System system generates activation Y Q R 5 M B C D ohm out dry contact provided needed to activate input external unit relay is EVX ATM to be mounted within Evax System cabinet System driving External Audio System circuit provides activation on presence of audio signal 5 wiring connections wire clamp screw 14 18 AWG wire clamp screw 12 18 AWG wire entry terminal 18 26 AWG gauge determined by circuit load VDC Settings P C 5 1V X V Y Q R 5 M B C D or 70V is at J4 ohm out dry contact available needed to activate input external unit to be mounted within external system cabinet 6 Audio input w VOX signal input provides activation Wiring when used in addition to other Audio Sources wiring connections wire clamp screw 14 18 AWG wire clamp screw 12 18 AWG wire entry terminal 18 26 AWG gauge determined by circuit load 70V selected at J4 600 Ohm Settings P C 1 1V 25V 70V X V EVX 25 Q R 5 M B C D Y EVX 25 X jumper selects VOX activation Signal alone enables input NOTE Additional ATM and EVX RM Remote Microphones 1 5028 Rev D 3 of 4 Audio into FNV MP 7 600 ohm balanced line 25VRMS or 70 VRMS input Neg required if external source is other than ohm 1VRMS balanced Neg Input Dry activation Figure 3 for jumper settings wiring connections wire clamp screw 14 18 AWG wire clamp screw 12 18 AWG wire entry terminal 18 26 AWG gauge determined by circuit load 1 5028 Rev D 4 of 4
