Example 1: Keypad and Fire Alarm System
Use of cable monitoring e.g. from Fire Alarm System
If cable monitoring is not used, the input has only one threshold (G1).
If the input voltage is above this threshold it is inactive.
If the input voltage is under this threshold it is active.
Cable monitoring type "2"
Type "2" is used in conjunction with WSA 306.
This type of cable monitoring is the most secure because it detects
both interruption and short circuit.
Limit values 2.8V, 0.26V and 12V are used.
Cable monitoring Type "1"
Type "1" is used with WSA 501.
This kind of cable monitoring detects only interruption.
Limit values 2.8V and 12V are used.

Example 2: Wind/rain and rain sensors
WLA 330 and WLA 331– the settings of the sensors are set on the sensor.
WLA 340 – the settings of the sensor are programmable on the smoke panels touch screen.
X3
Additional power supply for sensors etc.
3.1 min. 18V max. 29V additional power supply with back-up batteries, max current consumption 50mA
3.2 min. 18V max. 29V additional power supply without back-up batteries, max current consumption 200mA
3.3 GND / 0V
Only use additional power supply with additional power supply (X3.1) if really necessary, as this will influent on the life
time of the back-up battery.
