U.S. Patent 7,418,8000
5.1.3.
Electric Strike:
The CONCIERGE 23DR is designed to work with 24VDC electric strikes. If an electric strike
is used, follow the instructions included in the packaging from the electric strike manufacturer to
assemble the strike and install it in the door jamb.
Before installation make sure the strike is set to your desired mode – ‘fail safe’ or ‘fail
secure’. ‘Fail safe’ mode means that if the strike were to fail, its latch will swing freely. If in
‘fail secure’ mode and the strike were to fail, the latch will stay locked. Therefore, a person
would be required to turn the door knob to open the door. The models CONCIERGE ESP and
CONCIERGE ESPAR are provided in the ‘fail secure’ mode, which is recommended.
