The AI-NVP-RA sub station is vandal proof, and can be used with the AI-900 system. Designed for Rescue 
Assistance applications and ADA compliance, this unit features Emergency and Braille signage, a large red call 
button, and "Call Placed/Call Answered" LED indicator. A remote indicator can be added for better visibility of a 
station's status.  The AI-NVP-RA can be flush mounted to a 3-gang box or mud ring, or surfaced mounted into the 
SBX-NVP surface mount box. Tamper proof screws are provided, along with a tool for installation.
