Edwards ANSZS2A 4B Zone Splitter Install

and ANSZS4B Zone Splitter Sheet Do not leave a zone switch turned on when as this leaves the zone unsupervised an alarm state the ANSZS2A and ANSZS4B default to All operation On activation of the ANS voltage all zones are automatically selected and receive the tone and message Modules have a field selectable for alarm zone activation only if the FACP has the ability provide separate pull down inputs a zone has a short fault a PTC thermistor for the zone excluding the zone from output and allowing the other to continue operation Once the short is removed the line must be disconnected for 30 seconds to reset the 24 Vdc 45 mA All Call 130 mA trouble relay TB2 7 8 and 9 rating 1 A at 30 Vdc resistive load Restricted to Class II or power limited Interconnected equipment is unsupervised so it be in the same room and mounted within 20 feet of module circuit EOL 10 k description ANSZS2A and ANSZS4B Zone Splitter modules are for use with the ANS25 ANS50 and ANS100 Audio Systems Their purpose is to enable the output of ANS to be split into multiple zones for paging and alarm modules accept input from the ANS speaker output and selectable output relays to distribute the output to the zones The modules can be cascaded to increase number of zones modules provide supervision of the individual zones for and short conditions Indicator LEDs display active or conditions for the individual zones A fault condition is to the FACP through the same supervisory path as ANS25 ANS50 or ANS100 can be selected manually by switches or through pull inputs In the event of an alarm condition the module to All Call operation The All Call feature can only be if the accompanying panel has zone control zone is limited to no more than 25 W and the total load must not to exceed the output rating of the ANS output can be set to 25 or 70 Vrms selected by a position on the ANS25 ANS50 or ANS100 normal standby the ANSZS2A and ANSZS4B supervise speaker zone wire loop The ANSZS2A provides Style Y and the ANSZS4B provides Style Z supervision an open or short fault is detected in a zone the yellow for that zone turns on A NC relay contact opens to a corresponding fault signal to the FACP providing of the ANS faults in zone circuits are not reported by the or ANSZS4B but are detected and reported by the ANS50 or ANS100 manually select a zone the operator turns on the zone switch The red LED for the switch lights output relay activation is enabled On activation of the PTT from the ANS the output relay connects the zone to the speaker output While the zone is selected supervision is 2013 UTC
