The Verkada BX21 is a wirelessly controlled alarm output device that allows customers to connect 12/24 volt sirens, strobes, or other alarm signaling devices.
Supported Output Devices
The Verkada BX21 has 1 NO/NC alarm output, with a max power draw of 2.5amps. The most common output devices are sirens, bells, and strobe lights that are activated when an alarm is raised. From Command, users can select outputs to turn on in response to an alarm. When an alarm is raised, the relay supplies power to those outputs. Multiple output devices can be wired in parallel so that activating a single output can turn on several devices simultaneously.
Supported Signal Devices
The Verkada BX21 supports Two-wire devices, such as door contacts, which are wired to the input and GND terminal. It does not matter which wire goes into which terminal.
Supported Power Devices
The Verkada BX21 takes a 12v DC at 2.5amps or a 24v DC at 1.25amps. This is connected to the GND and 12-24v terminals. It is recommended that if you are using an output device that draws a lot of current, the max amperage power supply should be used to avoid problems.
