Electrified Hardware Knowledge

Electrified Locks

Common Applications

Security control centers  -  Cashier rooms  -  Fire safety exits  -  Stairwell doors  -  Telephone equipment rooms  -  Computer rooms  -  Hospital equipment  -  Narcotics areas

 

Common options

 

Electrically Locked (Fail Safe)

• Outside knob/lever is continuously locked electrically

• Latch bolt is retracted by key outside or by knob/lever inside

• Switch or power failure allows outside knob/lever to retract latch bolt without use of key

• Auxiliary latch deadlocks latch bolt when door is closed

• Inside knob/lever always free for immediate exit

 

Electrically Unlocked (Fail Secure)

• Outisde knob/lever is unlocked electrically

• Latch bolt is retracted by key outside or by knob/lever inside

• Auxiliary latch deadlocks latch bolt when door is closed

• Inside knob/lever is always free for immediate exit

• Switch or power failure lock remains locked

 

Request to Exit (RX) Electrified Lock

• Lock can function as a normal non-electrically controlled lock or it can be an electrically locked or unlocked lock

• A micro switch positioned inside the lock case monitors the retractor crank and is actuated when rotation of the inside or outside knob/lever rotates the retractor hub

• The switch signals the use of that opening to security systems, allowing a non-disruptive means of immediate egress

 

 

Electrified Exit Devices

Common Applications

Hospitals  -  Schools  -  Institutions  -  Government facilities  -  Office buildings

 

Common options

 

Electric Latch Retraction

• Remote unlocking ability for exit devices

• A control station operator can flip a switch to retract the latch bolt and immediately change an exit only or latched door to push-pull operation

• Latchbolt can be retracted momentarily or for extended periods of time

• Can be used with automatic door operators

• Can be applied to fire-rated devices when under the control of an automatic fire alarm system

• A continuous current electric transfer must be used for transferring power from the frame to the door

 

Electric Trim

• A control station enables the remote locking and unlocking of outside trim of an exit device

• Signal switch monitors the remote outside trim (can be used to lock or unlock)

• Standard as fail safe; can be field convertible for fail secure

• Outside trim cylinder retracts the latch bolt for mechanical override

• A continuous current electric transfer must be used for transferring power from the frame to the door

 

Request to Exit Signal Switch

• Used to signal the use of an opening from the push side

• When the push pad is depressed, the switch is activated; switch can sound an alarm, signal a control panel or activate an auxiliary device

• A continuous current electric transfer must be used for transferring power from the frame to the door

 

Latchbolt Monitoring

• Signal switch monitors both egress and access of an opening

• When the latchbolt is retracted, the switch is activated

• Can be connected to a security console or used as a single door alarm when used with a horn and power supply; a continuous current electric transfer must be used for transferring power from the frame to the door

 

Signal Switch

• Used to signal the unauthorized use of an opening

• Available in rim, mortise, and vertical rod

• One switch monitors the touch bar and latch bolt assembly

• Second switch is connected to the mortise cylinder for alarm bypass

• Can be connected to a security console or used as a single door alarm when used with a horn and power supply; a continuous current electric transfer must be used for transferring power from the frame to the door

 

 

Electrified Strikes

 

Operation - Mechanism releases and allows door to open without retracting the latchbolt.  This is accomplished by the electric strike lip (keeper) swinging out of the way of the latchbolt and allowing the door to open.

 

Application - Electric strikes are used in conjunction with mechanical locksets as an inexpensive means of access control or as a latch releasing device when used with handicap door operators.

• Can be mounted in the frame or the inactive leaf of a pair of doors

• Can be fail safe or fail secure operation (Fail secure operation required on fire rated doors)

• Various voltages of operation; AC or DC, depending on model and manufacturer

• Filtered and regulated power is not typically required for electric strikes

• Models for hollow metal, wood, and aluminum applications available

• Models available for cylindrical locks, mortise locks, rim exit devices and vertical rod exit devices

• Some models come with multiple face plate configurations to allow compatibility with various manufacturers mortise locksets

• Some models can also accept deadbolts of mortise locks 

  Caution:  If deadbolt on mortise lock is retracted, electric strike keeper will not re-engage when door closes

• Retrofit models available for existing 4 7/8" ANSI strike preps; some models may require slight modification to frame face

• Options available with certain models:

   • Latchbolt monitoring (monitors the position of the latchbolt)

   • Lock cam monitoring (monitors the position of the strike lip or keeper)

   • Combination latchbolt & lock cam monitoring

   • Combination latchbolt monitor and lock cam monitor with auxiliary switch

 

 

Magnetic Locks

 

Operation:  Door and frame held secure by strong electromagnetic bond between the magnetic lock and its armature; one of which is attached to the door and one which is attached to the frame. 

 

Application:  Magnetic locks are commonly used for access control or delayed egress applications. 

Life Safety Codes should be considered prior to using magnetic locks.  Consult your Local Authority Having Jurisdiction (AHJ).

• Models vary by holding force required.  Holding forces range from 600 lbs. - 3000 lbs.

• Available fail safe only

• Various voltages of operation; AC or DC, depending on model and manufacturer

• Not for use on fire rated doors unless a separate "self latching" device is used (Consult Life Safety codes for your specific application.)

• All models must be connected to the building's fire alarm system to allow for free egress upon activation of the fire alarm or loss of power in emergency situations

• Models for hollow metal, wood, aluminum, and glass door applications

• Most models require a separate control box; some models have an integral controller

• Most models require filtered and regulated power

• Surface mount and concealed models available

• Models for sliding doors and cabinets available

• Common options available:

     • Door status monitor

     • Magnetic bond sensor

     • Adjustable time delay

     • Anti-tamper switch

Accessories

• Angle brackets, door brackets, filler plates, dress covers

• Exit/Sensor Bars or Push/Pull Touch Sensor Handle

• Scanners

• Push buttons, keypads, card readers, proximity readers, etc.

• Monitor Console

• Power supplies/Controllers

 

 

Electrified Door Closers

 

Self Closing

• Doors that when opened and released, return to the closed position

• Provides single point hold open for fire and smoke barrier doors

• Conforms to life safety code NFPA 101

 

Automatic Closing

• Door that is normally open but closes when the automatic closing device is activated

• Provides single point hold open for fire and smoke barrier doors

• Upon loss of power, door automatically closes

• Interfaces with alarm systems

• Conforms to life safety code NFPA 101

 

Power Operated Fire Doors (ADA)

• Designed primarily for manual opening applications that occasionally require automatic opening either electronically

  or pneumatically

• For single or multi door openings

Pneumatic

• Can be used as a normal door closer or opened

  automatically with the use of a button

• Pressurized air automatically opens the door

• Components needed: automatic operator to

  provide the door control, a control box that

  contains the valves and electrical timing

  circuits, actuators to start the system, and a

  compressed air source

• Available for push side, pull side and concealed mountings

• Finishes: standard powder coated, optional custom powder coated, or optional plated
