PRS-4AEX4 Audio Expander

• Eight programmable control inputs linked to 16 outputs
• Two serial interfaces to call stations or other keypads
• Up to 16 keypads can be connected to one call station

The call station keypad kit is used in combination with a call station kit or call station basic to make manual or pre-recorded announcements to any assigned zones, or to execute pre-defined actions. It is functionally equivalent to the LBB 4432/00 Call Station Keypad. One of the main applications is the development of fireman’s panels. However, since the call station keypad has eight programmable input connections, each with two associated output connections; it is well suited for other control applications.
