Changing Perceptions
Defining a Maglock
What is a Maglock Purpose of Maglocks Types of Maglocks Why are Maglocks Dangerous Why use Maglocks
What is a Maglock?
Door Hardware appliance (Lock) Electrically powered coil magnet Matching armature plate Made of stainless and ferrous metals Generates
60 to 1800lbs of holding force
What is a Maglock?
Options: Door Position Sensor Bond Sensor Delayed egress control module Voltage regulator module
Location: Normally at top of door on the inside Can be used outdoors* Can be used for tricky locking situations
Deters Locked door is a deterrent*
Delays Locked door slows down a burglar*
*However: Maglocks release on fire and on loss of power, which limits these factors
Purpose of a Maglock
Types of Maglocks
Standard Delayed Shear Gate (Exterior) Special Purpose
Typical Office Building Single or Double “L” or “Z” bracket
Standard Maglock
Typical in Retail Stores Built-in Delay (15sec) Alarmed Signage Required
Delayed Maglock
Typical in Sliding Doors Often includes Pins or “Fingers” Rarely Used as “Strength is Unreliable”
Shear Maglock
Typical in Daycare Outdoor Rated* Release is of Concern Swing or Sliding Action
Gate Maglock
Floor Maglock Sliding action Strength is a concern Wear & Tear is a concern Rusting is an issue
*Not Recommended
Special Purpose Maglocks
Why are Maglocks Dangerous
Locks the Door in both directions Requires Intervention to release Keys do not override If installed wrong, can trap people
Why use Maglocks
Traditionally for Glass Doors High Security Doors For Mantrap Doors For Doors that need to lock in
both directions
What is the Code
Alberta Fire Code 2014 Alberta Building Code 2014 ABC - Appendix A
Division B - Part 3
Alberta Fire Code 2014
1) Means of Egress shall be provided in buildings in conformance with the ABC.
Division B - Part 3.4.6.16
Alberta Building Code 2014
ABC 3.4.6.16.(1) Exit Doors must: Release in one action Use no keys Use no special devices Require no training
English Translation
Division B - Part 3.4.6.16
Alberta Building Code 2014
ABC 3.4.6.16.(2) & (3) Door Hardware: All Public &/or High Volume doors: Require only 90N to operate Require only 90N to swing door open
“Every Public (or Popular) door, must be operable by a 90 year old 90lb Grandmother”
English Translation
Division B - Part 3.4.6.16
Alberta Building Code 2014
ABC 3.4.6.15.(4) Maglocks must: Release on fire alarm Release by a single switch (accessible by authorities) Have no pins or latching device Have no residual holding force Do not require keys Do not require special knowledge Release by use of door hardware (single action) Release with 90N of force or less Release immediately or within 15 seconds* *Requires Signage
English Translation
Appendix A.3.4.6.15.(4)
Maglocks Should not replace regular hardware They must not be used indiscriminately Must be Fail-Safe in “Foreseeable Emergencies” All maglocks must be controlled from one switch Maglocks must not reset automatically
What is allowed by the Code
Reset Switch (ABC A.3.4.6.15.(4)) Single Switch is to control all Maglocks Normally installed in or beside main fire panel Maglocks may not rearm when panel returns to
normal Switch is used to reset the Maglocks Switch is part of the Fire alarm system and is to
be supervised Switch is usually keyed (Building Master)
What is allowed by the Code
Maglock with Panic Hardware • Maglock • Fire Alarm tie-in • Power transfer • Cardreader • Door Hardware
with request to exit
Code Compliant Example
Code Compliant Example
Panic Hardware Works with Glass
Maglock with Delayed Egress • Delayed Egress • Maglock • Fire Alarm tie-in • Power transfer • Cardreader
Code Compliant Example
Calgary “Local Customs” that were allowed Maglock Fire Alarm tie-in Push button exit Push/Pull Glass door Blue Pull station*
*Recommended
Previously Accepted Installs
Standata ABC 3.4.6.15.(4) Maglocks could be installed on office doors for:
○ Single Suite or Tenancy ○ Public not allowed unescorted into the space ○ Group D occupancy only (i.e. Business or Service) ○ Push button is within 600mm of door frame ○ Sign is next to button describing what it does
Issued in 1995 Not renewed in 2000 Therefore, Not Valid
History behind “Local Customs”
Why they are not code compliant Secondary action Specialized device Requires specialized knowledge
How to Wire them if used Shunts power to Maglock Acts as request to exit to controller
Push Buttons
Why they are not compliant Secondary action Specialized device Requires specialized knowledge
How to Wire them when they are used Shunt power to Maglock Alarm input to controller
Blue Pull Stations
Why Use them both? Software freezes Push button shunts power
“but only when Held” Blue pull station removes
power permanently Blue pull station requires
tool to reset
Blue Pull Stations
Why we don’t use them? They release door when triggered They can be released from the outside They will bypass the alarm They rely on software They are not ULC rated
Motion Sensors
Code Compliant Maglock Door Standard = $ 6,000/door Delayed Egress = $ 7,000
Previously “Accepted” Door Maglock with push button = $ 5,500 By Comparison….. Electric Lock = $ 5,000*
Cost of Door Control
Retail Exit Doors Need to prevent shoplifting
Cash Cages & Bank Doors Prevent theft
911 Call Centres Prevent Disruptions, Terrorism & Retaliation
Hospitals & Retirement Homes Protect Patients & Hospital Staff
Where do we use Maglocks?
Maglocks release on Fire & Power Loss Ergo, not as secure
Maglocks lock the door in both directions Ergo, not as safe
Maglocks are more expensive Require Fire Alarm Tie-in (often a hidden/forgotten cost)
The problem with Maglocks
Framed Doors Panic Hardware with Electric Strike Wireless Battery Operated Hardware
Maglock Alternatives
All Glass Door Alternatives
Framed Doors (Allows Traditional Hardware)
Glass Door Alternatives
Panic Hardware Using Electric Strike
All Glass Door Alternatives

Stand-alone Battery Operated Use Caution*
*Not all are
Approved Exit Devices
Conclusion
Maglocks always require: Careful Consideration To be used sparingly To use Alternatives when possible To be used safely
