1
Removable 4-pole terminal block (screw connector connected to the electronic module)
+Vout
Terminal from which it is possible to withdraw power, POSITIVE
- (GND)
Terminal from which it is possible to withdraw power, NEGATIVE
A
Terminal to power the system, polarity irrelevant
C
Terminal to power the system, polarity irrelevant
2
RJ45 LAN port (present on the electronic module)
AD639SR requires a LAN cable to connect to the LAN network. If the cable also carries PoE power supply, it will
not be necessary to supply the module with other power sources (for max 10W power). For higher powers it will be
necessary to power AD639SR with a 24Vdc 2A or max 18Vac 2.5A power source.
See also appendix 2 at the end of the manual for the correct wiring of the LAN cable to the RJ45 connector.

+
Connect here the positive of the flashlight or external device
- (GND)
Connect here the negative of the flashlight or external device
At the "+Vout" output there is a + 12Vdc voltage when the device is powered via PoE, otherwise, at
this output the voltage will be the same as at the terminals A-C. The use of "+Vout" is permitted as
long as it is not exceeded a maximum 200mA current consumption and the load has a protection on
the input current. Improper use of this output will permanently damage the unit.
Devices powered via PoE (Power over Ethernet) may only be connected with cables coming from
inside the building, they are not allowed connections to LAN cables coming from outside the
building.
To terminals 1 (ING1) and 2 (GND) must only be connected a relay contact or a button free from any
voltage to prevent permanent damage to the device.
Relay K1 is pre-wired to supply power to terminal 4 which supplies an external flashing light, relay
K2 is free for other uses by the user.
The power supplied by this terminal is protected and limited to 300mA maximum current, do not
connect devices with a higher power consumption as internal protection would be activated.
