Operating Mode 02: Restricted Access Control with Door Monitoring
Description
Restricted Access Control with Door Monitoring restricts Level 1 user access based on the status of Input I2 and provides door use annunciation on Output K2.
Level 1 cards are accepted only if the Input I2 sees a closed contact. Level 2 or 3 cards are not dependent on Input I2.
A downward read of all valid User Cards pulse Output K1, the strike control relay.
The upward read of a Level 2 card toggles the strike control relay, K1, in effect performing a lock/unlock function. The upward read of a Level 1 card will release an unlocked condi- tion.
Output K2 is pulsed to annunciate improper door use, such as
a)Forced Open condition, which occurs if the door opening was not preceded by the use of a valid card or an exit request, or
b)Held Open condition, which occurs if the door is kept open longer than the preset open time.
User Level Specifications
User Level 1
•A downward read will pulse Output K1 only if Input I2 is closed.
•A upward read ends an unlocked condition, regardless of the status of Input I2.
User Level 2 (and 3)
•A downward read will pulse Output K1 (no effect if the door is unlocked).
•A upward read will toggle the state of Output K1, locking or unlocking the door.
Configuration
Input assignments:
•Input I1 is connected to a door contact: closed contact signifies a closed door
•Input I2 is connected to the access control control contact, such as an external timer. User Level 1 cards are accepted only when a closed contact is presented to this input.
Upper LED assignment:
•The upper LED follows Input I2, the Access Control Input:
•Open Contact is displayed as RED
•Closed Contact is displayed as GREEN.
Notes
This mode is very similar to Operating Mode 1. The same caution should be observed regarding the ability to permanently unlock the door:
The 10 cards included in the original shipment are enrolled as Level 1 users. Be aware, that if they are modified or any subsequent cards are added as Level 2 users, an up- ward read will unlock the door - requiring another upward read (by any user Level) to release the locked condition. Add Level 2 users only if the lock/unlock function is desired.
Consider using Operating Mode 4 or 5 if restricted access is required, but the unlock function is not.
