What’s Inside an Electric Strike?

Basic Hardware Terminology

• Strike Plate

– Refers to the “metal plate” that is on the door

frame, that the lock latch enters when the door is

closed

• Electric Strike

– An electro-mechanical device that replaces the

standard “strike” that allows the door to be

opened without the lock latch being retracted (as

in normal use)

– Often also just called a “strike”

Basic Hardware Terminology

• Latch

– The piece (sometimes 1 pc, sometimes 3 pc’s) that projects from

the lock casing, and into the frame, which holds the door closed

• ANSI

– American National Standards Institute – an organization that

sets standards for the door and frame industry

• ANSI -Prep.

– 1-1/4 x 4-7/8 is the standard size of cut out for the strike plate (as

well as electric strike) in commercial door frames

Basic Hardware Terminology

• Mortise lock.

– A type of lock that is “mortised” into the

door through a cut out on the edge of the

door. Can be offset from center of cut out.

• Cylindrical Lock.

– A type of lock that is mounted into the door

through the “face” of the door

• Rim Lock

– A type of lock that is mounted on the face

of the door

Aluminium, Hollow Metal, Wood or Glass

Mortise, Cylindrical, Rim Exit Device

Type of frame:

Lock type:

When choosing an electric strike, there are several key questions you MUST ask:

Latch location: Centerline or offset

• Fail Locked or Fail Unlocked?

• Fail Locked – power fails the strike is secure.

Exit is granted from the inside, however,

door is secure from the outside. All exterior doors.

Definitions:

• Fail Unlocked – power fails the strike is unsecure.

Exit is granted from both sides of the door.

Internal, non emergency exit doors only.

Door hardware must be locked on both sides

of the door. Similar operation to a maglock.

• Operate on low voltage – 12 or 24 AC or DC

• Is the opening “fire rated”?

• If so, a “fire rated” strike should be used – tested to withstand

fire for up to 1.5 hours to ensure door remains latched.

All in one Electric Strikes!

• Unique design makes it

the most fail safe device

• Control both access and egress yet ensure safety

• Building Code considerations

• Positive latching recommended by

choice or code.

• Compatible with most door hardware including exit devices

• Limit access but allow free egress

• Fire rated openings

Electromagnetic Locks vs. Electric Strikes

Coffee Break!!!!!

National Building Code &

Ontario Building Code

Door Release Hardware

3.4.6.15.

What is the alternative to

Electromagnetic Locks?

Building owners chain or pad lock doors to prevent theft!!!

Obviously, we do not want this to occur!

“Electromagnetic locks are intended for use where there is need for

security additional to that provide by traditional exit hardware. They

are not intended for indiscriminate use as alternative locking devices”.

“The design of these devices requires evaluation to ensure that their

operation will be fail-safe in allowing exiting in the event of

foreseeable emergencies”.

Electromagnetic Locks – NBC & OBC Appendix

A-3.4.6.15 (4)

The solution? Use proper locking hardware

while following the appropriate code to ensure

life safety!

There are three sets of Magnetic Lock standards in Canada

2. Ontario Building Code – applies to all non-federally owned

or leased buildings in Ontario.

1. National Building Code – applies to all non-federally owned

or leased buildings outside of Ontario.

3. Government of Canada (HRSDC) – applies to all federally

owned or leased buildings in Canada.

National Building Code

Door Release Hardware

3.4.6.15.

Electromagnetic Locks are permitted when…….

National Building Code 3.4.6.15 (4)

• The building is equipped with a fire alarm system,

• The lock releases immediately upon actuation of a

manually operated authorized switch,

• The lock does not incorporate latches or pins,

• The lock releases upon actuation of the alarm signal,

• The lock releases immediately upon loss of power

controlling the locking mechanism and its associated

auxiliary controls,

Electromagnetic Locks are permitted when…..

National Building Code 3.4.6.15 (4)

• A sign is mounted on the door indicating the lock

will release within 15 seconds of applying pressure

to the door hardware.

• A force of not more than 90 N applied to the door

hardware initiates an irreversible process that will

release the device within 15 seconds and not relock

until the door has opened,

• Upon release, the lock can be reset manually by

the authorized switch,

Ontario Building Code

Door Release Hardware

3.4.6.15.

(a) an exit from a floor area containing an assembly occupancy

has an occupant load greater than 100

(b) a door leading to an exit lobby from an exit stair shaft, and

an exterior door leading from an exit stair shaft in a building

has an occupant load greater than 100,

(c) an exit door from a floor area is considered a high hazard

industrial occupancy

Openings require an Exit Device – No occupancy restrictions in NBC

Electromagnetic Locks are NOT permitted when……

Ontario Building Code 3.4.6.15 (2)

(b) The building is an elementary or secondary school

Ontario Building Code 3.4.6.15 (5)

Exit Devices or Panic Hardware

Ensures a large number of people can exit a building in an emergency – OBC Appendix

In Ontario, Electromagnetic Locks are permitted…..

3. When a permit is requested from the appropriate

building department.

4. When the appropriate drawings are provided detailing

location of pull stations, magnetic locks, etc.

1. In most other applications, however, please check

with the local authority having jurisdiction.

2. On exterior doors leading from exit stairs in Group B,

Division 2 or Group 3 major occupancy – Care & Detention

Electromagnetic Locks are permitted when……

Ontario Building Code 3.4.6.15 (4)

• The building is equipped with a fire alarm system,

• The locks do not incorporate latches or pins,

• The lock releases upon actuation of the alarm signal

in single stage fire alarm system,

• The lock releases immediately upon loss of power

controlling the locking mechanism and its associated

auxiliary controls,

• The lock releases upon actuation of the (1st stage) alert

signal in a 2 stage system except in care and detention

occupancy, where it can release on (2nd stage) alarm signal,

Electromagnetic Locks are permitted when…..

Ontario Building Code 3.4.6.15 (4)

• The lock releases upon the operation of a manual

pull station located 600 mm from the door.

• The lock releases upon a fault between fire alarm control

panel and the controller of the locking device

• The lock releases immediately upon actuation of a

manually operated authorized switch located in main

entrance or central alarm and control facility,

• A legible sign reading Emergency Exit Unlocked by

Fire Alarm is permanently mounted on the door,

Electromagnetic Locks are permitted when….

Ontario Building Code 3.4.6.15 (4)

• Emergency lighting provided at the doors.

• The operation of the switch causes an audible signal

and a visual signal to be indicated at the fire alarm

annunciator panel and at the monitoring station,

• The lock must be reset manually by the switch,

Note: OBC does not reference Delayed Egress!

Human Resources and Skills

Development (HRSDC)

Building Safety (Door Release) –

Canada Labour Code Part II –

COSHR

No. 922-1-1-IPG-044

Electromagnetic Locks are permitted when……

HRSDC Building Safety (Door Release)

• Same basic requirements as NBC with two additions.

• The electromagnetic lock and the primary door opening

hardware are designed and installed in conformance with

CAN/ULC-S533, Standard for Egress Door Securing and

Releasing Devices.

• The total delay in egress time by electromagnetic locks

from any point within the floor area to an exterior open

space is not more than 15 seconds.

The Electromagnetic Lock Power Supply

Fault detection

Fire alarm connection for emergency release

Instant unlock upon AC failure

Manual override connection

Manual reset connection

What is the key component that makes this all happen?

ULC Listed, if necessary.

New Advances in

ULC Listed Power Supplies

Choosing the correct Power Supply

Which electric locking product?

What voltage (V)?

What current rating (A)?

Such as an electric strike or an electromagnetic lock NOTE: Electromagnetic locks will require an Fire Disconnect Relay!!

Key Switches

Allows for authorized personnel to manually override and re-set the access control system

There may be other “acceptable” manually operated switches other than key switches allowed for use. However, building supervisor/security personal should be concerned with unauthorized access to system when considering acceptability of the proposed manually operated switch.

How do we achieve manual override and reset?

The locking device releases immediately upon the

operation of a manual pull station for the fire alarm

system located on the wall not more than 600 mm

(23-5/8”) from the door

In large addressable type fire alarm systems, a pull

station incorporating two sets of contacts MAY be

required to meet O.B.C. 3.4.6.15 (4) (f) ………….

“Immediate release”

Emergency Pull Stations

Building Code Signs

Alarmed Exit Devices

Designed to meet all building code requirements when the use of electromagnetic locks is prohibited!!

Allow free egress at all times but equipped with sounder to notify security that door has been opened!!

Electromagnetic Lock Considerations

• Positive latching is required in Fire Separations

• Access switch required i.e. Keypad, Card Reader

• Egress switch is required i.e. push button, motion detector

• Building must have a fire alarm system

• Limits both access and egress under normal conditions

Electromagnetic Lock Considerations

• Building must have manual override/reset switch

• Fire Alarm Disconnect Power Supply

• Magnet must release on loss of power to fire alarm

• Pull Station (DPDT if required)

• Consult Authority Having Jurisdiction

• Emergency Exit Door Sign

EMERGENCY EXIT UNLOCKED

BY FIRE ALARM

PUSH UNTIL ALARM SOUNDS DOOR CAN BE

OPENED WITHIN 15 SECONDS
