Digiplex/EVO Binding

This binding provides integration with Digiplex/EVO alarm systems from Paradox. It utilizes PRT3 module for serial communication.

Supported Things

PRT3 Module

Before the binding can be used, a serial adapter must be added manually. Select PRT3 Module and enter serial port parameters. Please refer to PRT3 module manual for instructions how to modify baudrate (default setting is 2400)


Once PRT3 Module is added and communication with the alarm system confirmed by its online status, please start discovery process to automatically discover (and add as new Things) all zones and areas defined in the alarm system.

Binding Configuration

There is no binding level configuration required.

User is able to send commands through control channel to arm/quick arm/disarm the zone. Every sent message is followed by the channel state change to either Ok or Failed depending whether command has been accepted by the alarm system. Note that PRT3 module is capable of handling more kinds of messages, but those are not yet supported by this binding. Message format is as follows:

Command String sent to the control channel
Regular Arm AA<pin>
Force Arm AF<pin>
Stay Arm AS<pin>
Instant Arm AI<pin>
Regular Quick Arm QA
Force Quick Arm QF
Stay Quick Arm QS
Instant Quick Arm QI
Disarm D<pin>

<pin> is your PIN as entered on a keypad.

Note: For security reasons please consider not storing your PIN in openhab configuration files.

Note2: Please consult your alarm system manual how to enable Quick Arm feature. It is not enabled by default.

For example, the following sitemap item can be used to send commands to the area and receive response status as modified color of a label:

Switch item=areaControl label="Actions[]" mappings=[QA="Regular Quick Arm",QS="Stay Quick Arm",D1111="Disarm"] labelcolor=[Ok="green",Fail="red"]
