RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, 
DO NOT REMOVE COVER (OR BACK). NO USER 
SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.

This symbol warns the user that uninsulated voltage within 
the unit may have sufficient magnitude to cause electric 
shock. Therefore, it is dangerous to make any kind of contact 
with any inside part of this unit.

This symbol alerts the user that important literature concerning 
the operation and maintenance of this has been included.
Therefore,  it  should  be  read  carefully  in  order  to avoid 
any problems.

T

here are special components used in this equipment which are important for safety. These parts are indicated 

by the ”

 

Y

 

” mark on the schematic diagram and the replacement parts list. It is essential that these critical 

parts should be replaced with manufacturer's specified parts to prevent X-radiation, shock, fire, or other hazards.

Do not modify the original design without permission of manufacture.

PCBs (manufactured) using lead free solder (PbF) will have a stamp on the PCB.

.

!2

This connector is used to connect an external system for
synchronization.

!3

This connector is used to connect with the VIDEO IN con-
nector of the monitor.

!4

Connects to the alarm input connector (terminal) of an
external device. When the camera detects motion, the
alarm output signal is supplied to the connected external
device (Open collector output: 16 V DC, 100 mA max).

!5

This terminal is used for connecting the camera to an exter-
nal day/night detecting sensor.

!6

Plug the power cord (supplied as a standard accessory)
into this socket and connect it to an AC outlet.

!7

This terminal is for connecting the 12 V DC or 24 V AC
power supply cord.

Connect to 12 V DC (10.8 V-16 V) or 24 V AC

(19.5 V-28 V) class 2 power supply only. Be sure to
connect the grounding lead to the GND terminal when
the power is supplied from a 24 V AC power source.
