1511S Operational Description (NFPA-101)
The 1511S operation complies with the following building and fire codes: NFPA 101; NFPA 1-UFC; UBC; IBC; IFC; SBC;
California Building Code. Listings: UL Listed: Special Locking Arrangements and Auxiliary Locks; California State Fire
Marshal (CSFM) Listed.
The door is normally closed & secured and/or latched. The model 1511S Exit Check secures the door in the locked
condition, and the display shows the preset delay time.
Activation of the 1511S Exit Check is made by releasing the door latch and applying up to 15 lbs. of pressure to the door,
giving a pre-activation warning tone. (A 1 or 2 second nuisance delay will prevent false activation of the alarm).
When the nuisance delay time has been exceeded, the Exit Check begins the irreversible door release cycle. At this
time the display continues to count down, the verbal warning continues and an alarm output is provided to alert
personnel of an unauthorized exit.
The integral digital countdown display and voice commands inform the person intending to exit of the seconds remaining
to unlock. The Exit Check will release the door after the 15 or 30 second delay cycle has expired, allowing free egress. A
steady warning tone with the voice command “Exit Now” will sound until the Exit Check is reset by authorized personnel.
