Arming/Disarming
The Reader Expander allows a user to arm and disarm an area from a reader input when associated with a
door:
Deny access to a user based on the status of the area reducing false alarms
Dual presentation of the card can arm an area associated with the entry or exit direction of the door being
accessed
Fail to arm programmable output can be programmed to provide feedback in the event areas fail to arm
when using card reading functions
Prevent access to a keypad using a card and PIN function or allow card presentation to automatically login
the user at the associated keypad
Disarm an area associated with an elevator floor on access when using the Protege 16 Input Destination
Reporting Interface in elevator mode
Connectivity and System Expansion
Expanding the Protege System with local zone (input) and PGM (Output) from Protege Reader Expanders allows
convenient cost effective expansion and added benefit of dual functionality on door monitoring zones:
6 or 8 zones (depending on the module) can be used to perform any system alarm and automation
functions with a dedicated enclosure tamper switch.
Configurable EOL resistor combinations
All zones are assigned functions that are processed by the Reader Expander for door control. Each function
can be enabled or disabled individually, as required.
Network RS-485 port used for all network communication functions and interconnects to other modules.
Upgradable Firmware
Utilizing the latest flash technology and high performance communication interface the firmware can be updated
using industry standard applications.
Local Monitored Power Supply (RDS2, RDI2, RDE2)
The RDS2, RDI2, and RDE2, operate from a 16VAC input, utilizing a low cost transformer and providing a fully
monitored 12VDC power solution using:
Deep discharge prevention of the battery with automatic electronic cut-off
Manual or processor controlled battery charge selection of 350mA or 700mA
Intelligent charging algorithm monitors battery and AC supply allowing optimum performance to be
achieved using standard lead acid batteries
Monitored signals for Battery Low/Disconnect and AC Failure using local trouble zones
