What is the difference between fail-safe and fail-secure electric strikes?
Fail-safe electric strikes unlock when power is removed, ensuring free passage during a power failure. Fail-secure electric strikes remain locked when power is removed, maintaining security. The choice depends on whether the opening is a required means of egress and the security requirements of the application.
Do fire-rated doors require special electric strikes?
Fire-rated doors require electric strikes that are listed and labeled for the specific fire rating of the opening. Fire-rated openings carry ratings of 20, 45, 60, 90, and 180 minutes. The electric strike must carry a listing that matches or exceeds the opening's fire rating. Fire-rated strikes must operate as fail-secure to maintain the fire barrier.
Can a Folger Adams electric strike be added to an existing door with a mechanical lock?
Electric strikes are designed to work with existing mechanical locks. The strike replaces the standard fixed strike plate in the frame while the existing lock remains unchanged. This makes electric strikes the most common retrofit method for adding access control to existing doors.
What is latchbolt monitoring and why is it important?
Latchbolt monitoring uses an integrated switch in the electric strike to report whether the lock's latchbolt is fully engaged in the strike. This signal is sent to the access control panel to confirm the door is secured. It is distinct from door position monitoring and is required for comprehensive security reporting.
What voltage do Folger Adams electric strikes require?
Most Folger Adams electric strikes accept 12 or 24 VDC, with many models featuring built-in voltage regulation that accepts a range of input voltages. Power is supplied from the access control panel or a dedicated low-voltage power supply. Verify the specific model's voltage, current, and duty cycle requirements during specification.
Can CDF supply Folger Adams electric strikes with a complete door assembly?
CDF supplies Folger Adams electric strikes through ASSA ABLOY's Banner Solutions distribution channel. Electric strikes can be configured as part of a complete door, frame, and hardware assembly in ProBuilder. CDF's sales engineering team provides specification support for complex access control projects.
What information is needed to specify a Folger Adams electric strike?
Specify the lock type (cylindrical, mortise, rim exit device, or deadbolt), frame type and material, fire rating of the opening (if applicable), fail-safe or fail-secure operation, voltage available from the access control system, and whether latchbolt monitoring is required.
Are Folger Adams electric strikes suitable for exterior doors?
Folger Adams manufactures electric strikes rated for exterior applications with appropriate weather resistance. For exterior doors, verify the strike's environmental rating and consider fail-secure operation to maintain security during power outages. Exterior strikes may require weatherproof housings depending on the exposure conditions.
