Pelco Manual C1927M (5/99) 13
PELCO’S TIME-LAPSE VCRS
You can connect one of Pelco’s Time-Lapse VCR Models TLR2024, TLR2096, or TLR2168
to the multiplexer as follows (refer to Figure 7):
1. Connect BNC video cable between the VCR connectors on the multiplexer and the
VIDEO connectors on the VCR.
2. Automatic Speed Tracking lets the VCR control the multiplexer’s recording speed. It is
the most efficient recording method. To wire (refer to the “B” lines in Figure 7):
a. Connect the VCR’s CLK output to the multiplexer’s head switching (HS) input to
synchronize camera switching.
b. Connect the multiplexer’s ground terminal to the VCR’s GND terminal.
3. Alarm recording starts and stops recording when there are alarms. To wire (refer to the
“A” lines in Figure 7):
a. Connect the multiplexer’s normally open (NO) relay terminal to the VCR’s SET IN
(alarm input) terminal.
b. Connect the multiplexer’s common (C) terminal to the VCR’s GND terminal.

section.
ALARMS
Alarm inputs require a ground signal through a contact opening or closure, such as a switch
or relay.
To wire the alarm inputs (refer to Figure 8):
1. Connect one wire from the alarm source (for example, door) to one of the alarm input
pins of the multiplexer. The alarm input must correspond to the camera input. There is
only one alarm input per camera.
The eight-pin plug-in terminal blocks may be pulled out of the connectors on the back
of the multiplexer to facilitate ease of wiring.
2. Connect a second wire from the alarm source to one of the ground connections on the
six-pin plug-in terminal block on the back of the multiplexer.
