The device provides protection against polarity reversal when connecting the battery.

How long will the device work with a standard battery?

If the battery is connected with a capacity of 1100 mAh, the device will work for at least 12 hours.

How to connect the main power?

Terminals labeled "12V" and "GND" are used to connect the main power supply. The positive power adapter cable must be connected to the terminal labeled “12V”, and the negative cable to the terminal labeled “GND”.

The device provides protection against polarity reversal when connecting the main power supply.

What can be connected to the terminals "1WR" and "LED"?

The terminal labeled “1WR” is used to connect the signal (DATA) cable of the ТМ-reader или wired temperature sensor.

How to connect additional devices?

Each of the terminals - "Z1" and "Z2" - can be used as a zone (input) or an open collector (output).

Turn on or off the zone of the device can be on the tab “Zones".

If the zone is turned off, the terminal is considered an open collector and can be used when setting up automation. The name of the open collector coincides with the marking of the terminal ("Z1", "Z2").

A positive load cable, the power of which will turn on when the open collector is closed, must be connected to the “12V” terminal.

If the zone is enabled, it can only be used as an input. The signal cable of the zone must be connected to the “Zx” terminal, and the common cable of the terminal - to the “GND” terminal.

How to connect the Beacon and Siren?

The answers to this question are discussed in detail in separate articles:

• Automation: Siren of Nord GSM Mini and Air

What is the difference between Air 15.1 and Air 15.2?

1. Clamping terminals replaced by removable;
2. A beeper is installed instead of speaker;
3. An additional GND terminal has been added; therefore, the sequence of the lower terminals has been changed:
   * It was (bottom up): GND, 12 V, 1WR.
   * It is now: 12 V, GND, GND, 1WR.
