Digital DDA Interface
The Network 16 DDA Interface enables the existing Honeywell Emergency Assist Alarm kit (EVCS-TAP) to be easily installed onto the Network 16 loop based EVCS System.

The DDA Interface contains a short circuit isolator to ensure a fault tolerant loop connection and has a built-in output to connect a wide range of sounders/ and indicators (supplied separately) for user reassurance in the event of a user activation.
