Figure 11. Installing an external device
The AlertMaxx unit has volt free contacts to connect external devices such as an alarm or beacon. When the
alarm is activated the relay sends a signal once every second.
The volt free relay is designed to accept devices with a maximum load of 0.5A and voltage between +6 to
7V DC. If external devices fall outside these parameters, the external device must be powered by an external
power supply.
Figure 11 below shows the volt free terminal connections.
