Connecting Security Detectors and devices
Technically, it is also possible to connect detectors with one or without any resistors, but in this case the security
level is seriously decreased and an installer must respond.
The installation interface has, for security detectors, predefined default normal and alarm state voltages. These
values are based on the nominal resistor values recommended by Yoga.
NB! Any resistors can be used but the installer must consider the fact that a whole line may have a maximum 15
kΩ resistance and the gap between alarm and normal states must be at least 1.5V.
