CONNECTING SWITCHES & I/O
OUTPUTS
... These are open collector transistors which can drive a load connected to the
internal 12V
12V 12V
12V supply or an external supply of up to 12V
12V 12V
12V. When the output is ON
ON ON
ON it can sink a
current of 100mA 100mA 100mA 100mA. This example shows a siren connected to the internal 12V 12V 12V 12V supply.
To use a mains powered siren, connect the alarm output to a suitable external relay. These
however, are integral on some makes of siren.
DIGITAL INPUTS ... These are opto-coupled inputs that can be linked to use either the
power INT

must be moved to other position and the exV +V +V +V connected to the EXT+VE EXT+VE EXT+VE EXT+VE
connection. The external switch or device must be capable of sinking 5mA

input. All inputs can be set in the software to be active High or Low.
This example shows a door switch connected to the internal power supply. LK5

AUX IN … This allows for the connection of certain interfaces such as the PC PC PC PC----EI00 EI00 EI00 EI00----XXX XXX XXX XXX
device to integrate third party equipment with the door controller. Supply voltage is
selectable between 5V
5V 5V 5V and 12V 12V 12V 12V via the link.
