12.1 Introduction and Key Features
The PC-25T Power Supply is designed for use with all Rosslare secured
series stand-alone access control units. The PC-25T contains two
power supplies. One power supply is for the lock strike, the other is
for the access control unit (ACU).
The lock strike is attached directly to the power supply. This design
isolates the lock from the ACU securing the functionality of lock even
if the ACU is tampered with. When a valid code is entered at the
ACU, the ACU communicates to the power supply using a Rosslare
proprietary protocol sending a command to activate the lock.
Similarly, the Release to Exit (REX) button is attached directly to the
power supply. When the REX is pushed, the power supply
communicates the REX request to the ACU and then the ACU
communicates back to the power supply to activate the lock strike.
If the data line between the ACU and the power supply is cut, the
system immediately detects that the data line has been tampered
with.
