SpeakerCraft MZC-88 Installation Instructions

MZC-88 Installation Instructions Page 43
DOORBELL/STATUS
Loop the Doorbell/Status Trigger Inputs using standard 3.5mm (
1
⁄8”) Y adaptors to simultaneously trigger the Page Inputs on
multiple MZC-88’s.
NOTE 1: This application requires standard Y adaptors. DO NOT use the SpeakerCraft SAC-1.0 Y adaptor. The SAC1.0 has
‘steering’ diodes that will interfere with the signal path in this application.
NOTE 2: These inputs will not function without proper configuration in EZ-Tools.
1. Terminate the Trigger Source wire with a 3.5mm mini plug. POLARITY: TIP=+V, SLEEVE=GND.
2. Connect Trigger Source to a Y adaptor as shown in Figure 24.
3. Daisy-chain the Y adaptors to all MZC-88’s in the chain as shown in Figure 24.

COMMON IR OUT
The Common IR Out jacks from multiple MZC-88’s can be paralleled and looped using standard 3.5mm (
1
⁄8”) Y adaptors for IR
control of a common device (not connected to one of the Source Inputs) from any MZC-88 in the chain.
NOTE: This application requires standard Y adaptors. DO NOT use the SpeakerCraft SAC-1.0 Y adaptor. The SAC1.0 has
‘steering’ diodes that will interfere with the signal path in this application.
1. Daisy-chain the Y adaptors to the Common IR OUTS on all MZC-88s in the chain as shown in Figure 25.
2. Connect an IR emitter to the Y adaptor assembly as shown in Figure 25. Set the LO/HI Common IR Out switch to LO.
(Refer to Common IR Out, page 32.)
3. Attach the IR emitter to the device to be controlled over the IR eye on that device.
