Page 26 MZC-88 Installation Instructions
PHONE PAGE IN
Requirement - Use a quality, pre-made audio cable terminated with RCA connectors for runs under 15’. Pull quality,
shielded audio cable from the paging device to the System Head-End for runs up to 200’.
MAXIMUM LENGTH: 200’
NOTE: Some Telephone Control Panels can produce sufficient levels of RF radiation to interefre with MZC-88 perfomance.
It is recommended that Telephone Panels be located at least 15-20 feet from an MZC-88 to avoid interference.
Installation - Connect one end of the pre-made wire to the paging device line level audio out and the other to the
PHONE PAGE IN jack on the MZC-88 Rear Panel. Terminate the sheilded audio cable with an RCA connector at the
System Head-End. Terminate the paging device end as appropriate. Maintain proper polarity. RCA CONNECTOR
POLARITY: PIN=SIG; SLEEVE=GND.
VIDEO PAGE IN
Requirement - Use a quality, pre-made video cable terminated with RCA connectors for runs under 15’. Pull RG6 quad-
sheild coaxial cable from the camera/video device to the System Head-End for runs over 15’.
MAXIMUM LENGTH: Will vary by device. See the specification of the device being used or call the equipment
manufacturer. 40-50’ typical, up to 500’ on RG6 coaxial cable with some devices.
Installation - Connect one end of the pre-made video cable to the camera/video device composite video out and the
other to the VIDEO PAGE IN jack on the MZC-88 Rear Panel. Terminate the RG6 with an RCA connector at the System
Head-End. Terminate the camera/video device end as appropriate. Maintain proper polarity. RCA CONNECTOR
POLARITY: PIN=SIG; SLEEVE=GND.
DOORBELL/STATUS IN
Requirement - Pull 28-22AWG two-conductor stranded wire from the doorbell or sensed device location to the System
Head-End.
MAXIMUM LENGTH: Will vary. 500’ typical, up to 2000’ with some devices.
Installation - Terminate the 28-22AWG two-conductor wire with a 3.5mm mini plug at the System Head-End for
connection to one of the two Doorbell/Status IN jacks on the MZC-88 Rear Panel. Terminate the Doorbell/sensed device
end as appropriate. MINI PLUG POLARITY: TIP=+12V; SLEEVE=GND.
COMMON IR OUT
Requirement - Use a SpeakerCraft standard emitter (IRE-1.0, 2.0, 3.0, 4.0) when the Common IR OUT Switch is set in
the LO position. Use a SpeakerCraft high power emitter (IRE-5.0 Blaster) when the Common IR OUT Switch is set in the
HI position. Pull 28-18AWG two-conductor stranded wire from the location requiring System Common IR Control to the
System Head-End to extend the emitter wire as required.
MAXIMUM LENGTH: 1000’
Installation - Connect an emitter to the Common IR OUT on MZC-88 Rear Panel and set the HI/LO switch as
appropriate. Attach the emitter over the IR eye on the device to be controlled. When extending the emitter wire,
terminate the 28-18AWG two-conductor wire with a 3.5mm mini plug at the System Head-End. Terminate the other end
for System Common IR Control as appropriate. MINI PLUG POLARITY: TIP=SIG; SLEEVE=GND.
COMMON STATUS OUT
Requirement - Pull 28-18AWG two-conductor stranded wire from the device to be controlled to the System Head-End.
MAXIMUM LENGTH: 1000’
Installation - Terminate the 28-18AWG two-conductor wire with a 3.5mm mini plug at the System Head-End for
connection to the Common Status OUT jack on the MZC-88 Rear Panel. Terminate the controlled device end as
appropriate. MINI PLUG POLARITY: TIP=+12V; SLEEVE=GND.
STATUS IN
Requirement - Pull 28-18AWG two-conductor stranded wire from the sensed device(s) to the System Head-End.
MAXIMUM LENGTH: 1000’
