12 Multivision® Pro Installation and Operation Manual
NOTE: The Alarm Hold Input is not normally used and is
only provided for compatibility purposes. Alarm
duration control is better managed by the multi-
plexer. See Alarm Recording Control for more
details.
The alarm hold input accepts a normally closed contact type
or active high TTL/CMOS alarm signal. Connect alarms pin
36 to the alarm hold output of the VCR or other device. Con-
nect the remaining side of the output to ground (post labeled
gnd on back panel).
Alarm Hold Input
Alarm Output The alarm output is a contact type signal between alarms pin
17 (common) and pin 18 (normally closed) or pin 19 (normally
open). Connect the appropriate pins to the alarm input of the
VCR or other device. See Appendix D — Technical Specifications
for details.
Motion Alarm Outputs The motion alarm outputs use a TTL/CMOS type signal. Con-
nect each motion alarms pin (pins 20–35) to a TTL/CMOS
compatible alarm input on the VCR or other device. Connect
the remaining side of the output to ground (post labeled gnd
on back panel). Motion alarm output polarity is menu select-
able and defaults to active high.
Autodetect VCR Speed Pin 37 connects to the VCR to get the timing signal (it may be
named clock or trigger) so the multiplexer can switch to use
the same recording speed as the VCR. If the VCR changes the
recording speed, the multiplexer will automatically adjust the
speed to match. Check your VCR manual to see if the VCR
provides a timing signal.
Remote
The two RJ11 connectors are for the multiplexer remote con-
trol panel option or remote control commands.
Remote Control Panel Option Connect the cable provided with the remote control panel to
the remote in connector. If daisychaining to another multi-
plexer, connect the remote out of this multiplexer to the re-
mote in of the next multiplexer in the chain. The remote con-
trol panel and the multiplexer front panel operate identically
and may be used at the same time. See Remote Control Panel
manual for details.
