ELECTRIC STRIKES

ELECTROMECHANICAL SECURITY

An Electric Strike is an access control device used to lock and release doors. Electric Strikes are installed in or on the door frame and work in conjunction with mechanical door locks, on the principle of electronically controlling the rotation of the keeper. This allows doors to be opened without manual retraction of the mechanical door lock. Electric Strikes generally come in two basic field-selectable configurations:

• Power To Release (PTR)

In this configuration, applying power to the strike will cause it to unlock. The strike will remain locked in a power failure. However most access control systems are provided with backup batteries.

• Power To Lock (PTL)

In this configuration, applying power to the strike will cause it to lock. If there is a power failure or fire alarm condition the door will open merely by being pushed/pulled.

MONITORING FEATURES

Please refer to the particular Electric Strike part number in the brochure to obtain the features listed below.

• LOCK STATUS SENSOR (LSS)

The monitoring of the lock status (locked or unlocked). This is achieved by monitoring the movement of the internal locking mechanism.

• DOOR STATUS SENSOR (DSS)

The monitoring of the mechanical lock status with a switch assembly monitoring the tongue of the mechanical lock in the keeper of the Electric Strike. The switch provides NO/NC changeover dry contacts for remote monitoring.

• ANTI-TAMPER-MONITORING (ATM)

The ultimate monitoring of the device itself installed within the door frame.A switching assembly monitors the strike being removed from the door frame.
