The output is used to send signals to external systems such as sensors, heaters,

lights and so on. The output is an electronic switch (open drain) which can operate

with up to 25 V and 650 mA.

A 6-pin colour-coded cable is available for the optional connection of the I/Os. The

cable is plugged into the socket market ‘sensor’ on the Lock Node. For monitoring

tasks, up to three floating contacts can be connected between the green In-Common

line and one of the coloured (blue, green, yellow) lines (see following diagram):

In the LDB and LSM user interfaces, an open contact has the value 0 while a closed

contact has the value 1. In the diagram above, for instance, if contact 1 is used for

monitoring a door, then when the door opens it will generate an event: ‘input 1

transition from 1 to 0’ (if contact 1 is closed when the door is closed and open when

the door is open).

Internally, the output is formed by a transistor wired as an Open Collector. The white

and black wires are available for connecting up external devices (such as buzzers).

Note: out = white; earth = black.
