N.O. contacts are rarely used on security systems unless an end-of line resister is employed on the protective loop circuit. When connecting a N.O. magnetic sensor to the IEI unit, the switch portion of the sensor could be mounted on the door and the magnet would go on the stationary doorframe. These should be mounted on the protected (interior) side of the door. This will keep all the wiring on the door.
REX (Request-To-Exit) input is useful for applications where it is desirable to be able to momentarily unlock the door to admit individuals who are not authorized system users. A doctor's waiting room would be just one application for a remote R-E-X sensor. The use of a R-E-X sensor is also required to suppress ‘Forced Door Alerts' which will occur whenever someone attempts to leave a protected area where the Forced Door Alert is implemented. An interesting feature offered on the LS2/LS2P is a switch built into the inside lever trim which can be connected to the R-E-X input on the IEI to suppress Forced Door Alerts without requiring the installation of an external R-E-X switch. (An additional remote switch would still be required anyway if the client wishes to remotely control access.)
USEFUL CODE TYPES
Master Code: This is analogous to a Great Grand Master. A default code is set at the factory and the installer must install his own in order to commission the system. The client may also change this code after you leave. This is not a good idea because if they screw up, the ability to further program system might be inhibited without a reset. Better to let them play with the Supervisor Code which enables them to enter and remove users, but not to alter other system settings.
User Codes: Up to 2000 unique user codes may be enrolled. User codes may be from one to six digits in length. Keypad prompts prevent the same code to be enrolled for more than one user. A user may be entered as one of eight different types.
User types include:
- Extended Unlock: Opens the door for periods longer than the standard door open time (good for handicapped or deliveries).
- Toggle: Good for supervisors who are first to arrive and last to leave, unlocking the door during normal business hours.
- Single-Use Code: Good for vendors and visitors who will only be granted access one time.
- Emergency: These users cannot be locked out by other programming; will continue to operate the unit below the Low Voltage Inhibit Threshold.
- Communications Enable: Used by the system administrator to begin an data upload/download session from a PDA (LS2/LS2P models).

THE CRITICAL SAFETY COMPONENT IN ACCESS CONTROL
PDK3000 is a weatherproof, rugged all-metal 12-button keypad.
Probably one of the most important features of an electromechanical lock is the capability of controlling access offering a choice of authorization credentials.
