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.
