The V2000–STBY is an EN54–16 compliant optional Standby Interface Card that can be used with V2000 Voice Alarm Amplifier Mainframes to provide control of hot swappable ASL D Series power amplifier modules across different V2000 Frames.

The standby interface card has RJ45 control connections and a 100V daisy chain connection for looping to other frames.

 Standby amplification can be provided internally within the V2000 or by means of an external standby amplifier. Use of an internal standby amplifier requires no standby wiring to be made. Use of an external standby amplifier requires a V2000–STBY module to provide the standby control and 100V speaker line connections between the V2000  frames
