There are many cases where we want the AJAX HUB to alert us with an alarm when a wired sensor gives an alarm or when a relay output (dry contact) is closed or opened.
- Water Pumps
- Wired Volumetric or Magnetic Detectors
- Domotic system
The only thing to consider is that the power supply of that device should be autonomous, unless it is low consumption (3 V) so that the power supply of the AJ-TRANSMITTER itself could be used.
What options do we have:
The AJ-DOORPROTECT has a wired input that can accept any device that has a dry contact output, the external device cannot be powered with this interface, and the autonomy of the AJ-DOORPROTECT is still about 3 years.
The AJ-TRANSMITTER has 2 inputs; one as alarm and one as tamper. Although the purpose of the tamper input exists to prevent sabotage, we can use it either as a pre-alarm or as a silent 24h notification, but with notification.
Moreover, the AJ-TRANSMITTER can feed other low consumption devices. Because of its 3.3V output.
