Alarm inputs

The alarm transmitter can either be digital and trigger an alarm when open or closed or analog,

balanced at 4.7kΩ. A number of typical installations are described below.

Figure 4 – Normally open/closed relays

Figure 5 – Balanced analogue

Figure 6 – Voltage of +5V to +12V with

limiting

Figure 7 – Voltage of -12V to -5V

1. Normally open/closed relays

When connecting the digital signals to trigger an

alarm when opening or closing, the inputs are

connected as such.

This connection can keep the control panel

galvanically isolated from the alarm transmitter.

2. Balanced analogue

If the signals that are sent to the alarm transmitter

are analogue, balanced at 4.7kΩ, the resistor is to

be mounted as such.

This connection can keep the control panel

galvanically isolated from the alarm transmitter.

3. Voltage of +5V to 12V with limiting

In some cases voltage must be limited on the

alarm port in the alarm transmitter in option 3. If

that is the case, insert a 5.1V Zener diode as

illustrated in the sketch.

This connection can keep the control panel

galvanically isolated from the alarm transmitter.

4. Voltage of -12V to -5V

The connection works no matter whether the

output from the control panel is low ohmig

(<500Ω) or high ohmig (>500Ω) when there is an

absence of voltage.

This connection galvanically couples the control

panel and the alarm transmitter.
