Applications:

• Failsecure Operation: Locked when de-energized, the failsecure mode is recommended for security applications, such as inner offices, equipment rooms and security mantraps. Loss of power causes all doors to lock. Battery backup is required for continued operation during a power loss.
• Failsafe Operation: Locked when energized, the failsafe mode is recommended for fire life safety applications, such as stairwell doors, perimeter exit doors and safety mantraps. Loss of power or a signal from the life safety system causes all doors to unlock for free uninhibited access and egress.
• Locked Both Sides: Unlocked by an access control, remote control or key from either side. Field reversible operation.
• 7830: Locked both sides, failsafe
• 7832: Locked both sides, failsecure
• Locked Outside Only: Unlocked by an access control or key from the outside. Uninhibited egress at all times by turning the inside lever handle. Field reversible operation.
• 7850: Locked outside only, failsafe
• 7852: Locked outside only, failsecure
• Locked Outside and/or Inside: Unlocked by an access control, remote control or key from either side. Alternately, unlocked by an access control or key from the outside and uninhibited egress at all times by turning the inside lever handle.
• 7835: Locked outside and/or inside, failsecure outside, failsafe inside
• Deadbolt Security, Locked Outside Only: Deadbolt projected by key cylinder or thumbturn. Outside lever retracts deadbolt when electrically unlocked. Unlocked by an access control or key from the outside. Uninhibited egress at all times by turning the inside lever handle. Turning the inside lever will also retract the deadbolt.
• 7870: Deadbolt security, locked outside only, failsafe
