Needs and Wants
Building Owners:
NEED: To control access to buildings using quick,
cost effective means
WANT: Quickest/cheapest method possible
Therefore:
MAGLOCKS = GOOD
Needs and Wants
Fire Protection and Life Safety Industry:
NEED: To get people out as quickly as
possible through unimpeded exits and
other means of egress.
WANT: To control or eliminate security
devices that may impede egress or
reduce the level of life safety
Therefore:
MAGLOCKS = BAD
Needs and wants
Ontario Building Code:
Maglocks are a fact of life.
Code Officials are empowered to regulate safety in
buildings from fire, structural collapse, air
quality etc.
Therefore:
MAGLOCKS = REGULATION

Door Release Hardware
3.3.1.12(2): A door in an access to exit shall be readily openable in
travelling to an exit without requiring keys, special devices or
specialized knowledge of the door opening mechanism (except
contained use area or impeded egress zone – (i.e. prisons and the
like).
– Access to exit: that part of a means of egress within a
floor area that provides access to an exit serving a
floor area.
– Means of egress: includes exits and access to exits and
means a continuous path of travel provided for the
escape of persons from any point in a building or in a
contained open space to a separate building, an open
public thoroughfare, or an exterior open space that is
protected from fire exposure from the building and
that has access to an open public thoroughfare.
Door Release Hardware
3.4.6.15.(1): ….locking, latching, and other fastening devices on
every exit door shall permit the door to be readily opened from
the inside with not more than one releasing operation and
without requiring keys, special devices or specialized
knowledge of the door opening mechanism. (3.4.6.16 in the
2012 OBC)
3.4.6.15.(4): Maglocks are permitted on exit doors if installed per
the code and if all doors in the access to exit that are also
provided with similar devices release per the code . (3.4.6.16 in
the 2012 OBC)
This pretty well takes in all egress doors.

WELCOME TO WHERE WE ARE TODAY
The 2006 OBC and the 2010 N.B.C
• NBC is the Model document for all other provincial
Building codes.
• Some provinces adopt the NBC in it’s entirety
• Other provinces use it as a base document and tailor
it towards their own specific provincial needs (as is
the case in Ontario).
• NBC enforced in Ontario on federally regulated
buildings (i.e. Buildings owned/ by the Federal
Government or leased by the Federal Government)
but sometimes the both NBC/OBC enforced for same
building. Enforce HRSDC Policy IPG-044.
• Federally, every maglock installation requires
submittal of plans and specifications to HRSDC for
review.
The 2006/2012 O.B.C.
•
Enforced by municipalities in Ontario
•
Overseeing body is The Ontario Ministry of Municipal Affairs and
Housing (MAH)
•
Excellent web page for information on BCC rulings:
http://www.mah.gov.on.ca/Page9815.aspx
•
Last BCC over 13 years ago. Last BMEC was 2009 and before that
1991 (for electromagnetic locks)
•
Don’t like a municipalities opinion? You can formally ask for an
opinion from the MAH
•
Every maglock installation will require a building permit
application with plans and specifications prepared by a
professional engineer or architect
•
Every maglock in Ontario requires an electrical permit
Important Excerpts – NBC/OBC
• “Electromagnetic locks are intended for use where there is a
need for security additional to that provided by traditional exit
hardware”
• THEY ARE NOT INTENDED FOR INDISCRIMINATE USE AS
ALTERNATIVE LOCKING DEVICES
• If more than one electromagnetic locking device is used in a
building, it is expected that one switch will release and reset all
devices simultaneously.
• If installed on doors in required fire separations, then must
have a positive latching mechanism as well.
Important Excerpts – NBC/OBC
Maglocks are also NOT permitted on exit doors in
– Elementary or secondary school, (OBC only)
– From high hazard industrial occupancies
– Doors having panic hardware (assembly
occupant loads over 100 people, doors into exit
lobbies and doors from exit stairs to outdoors
with a building occupant load over 100) –
except in residential care facilities.
OBC/NBC Interpretations and
Opinions
• Electromechanical locks now approved by HRSDC for
installation on Parliamentary Precinct Building except on
exit stair doors. Can be installed on service room doors
etc. EACH INSTALLATION WILL REQUIRE SPECIFIC
APPROVAL FROM HRSDC. (NBC)
• Chexit and electroguard and other delayed egress
devices are to be installed and operated in the same
manner, generally, as electromagnetic locks except
HRSDC require a manual pull station installed to release
the door immediately (NBC applications for federal
buildings by HRSDC). (NBC)
OBC/NBC Interpretations and
Opinions
•
Chexits do not require an adjacent MPS to release the device (OBC BMEC 917-155)
•
Chexits DO require an adjacent keypad to immediately release the device (OBC
– BCC 96-11-494)
•
NBC style maglocks permitted on exit doors in gaming premises but only if
smoke detectors provided in each room and corridor accessible to the public
and the building is sprinklered. Now written into the OBC (OBC)
– Pressing on door hardware will unlock door within 15 s and door does not relock until
it has been opened
•
15 second delay is cumulative of all locking devices – NOT 15 sec at each
locking device (HRSDC, municipal enforcement, Branch Opinion)
•
Each maglock installation to be inspected by Electrical Safety Authority. (OBC)
•
Maglocks are to release upon interruption of the electrical supply to the
building (both normal and emergency), the fire alarm system or the maglocks.
(OBC – Branch Opinion)
OBC/NBC Interpretations and
Opinions
• Failure refers to interruption of both the primary and
standby powers. (OBC - Branch Opinion)
• Release under ground fault conditions has been
interpreted in the past to mean a ground fault in the
primary 120 volt supply to the maglocks. (OBC – Branch
Opinion)
– Since clarified to a failure in the electrical circuit between the FACP and the
controller of the locking device. In the OBC now. Also includes failure of the
data loop in an addressable system
• Maglocks DO NOT have to release during the generator
transfer time so long as the transfer time is less than 15
seconds. If it is longer than 15 seconds, then all
maglocks must release. (OBC – Branch Opinion)
OBC/NBC Interpretations and
Opinions
•
Card access to release a door during non-emergency situations is
permitted to have up to a 15 second delay but signage has to be
posted on the door. (OBC - Branch Opinion – April 1995)
•
Maglocks are permitted on cross over floors but need MPS on
both sides of door and MPS in stair to be zoned with the stair.
(OBC - Branch Opinion – April 1995)
– Issue: Signage should not say “Emergency Exit Unlocked By Fire Alarm” – Should
Say “Accessible Floor. Door Unlocked By Fire Alarm”.
•
Chexit and Electroguard and similar are permitted but must
release on fire alarm, manual switch or after pressing on door for 2
seconds and 15 seconds later door releases (sign required) – NO
manual pull station is required – different from NBC which
requires a manual pull station. (OBC – BCC – 98-46-651)
– Based on a Home Depot project in Kanata – not stated anywhere else in the OBC
OBC/NBC Interpretations and
Opinions
•
Chexit and similar are permitted but must release on fire alarm,
manual switch or after pressing on door for 2 seconds and 15 seconds
later door releases (sign required) – NO manual pull station is required
– different from NBC which requires a manual pull station. (OBC –
BCC – 98-46-651)
– Based on a Home Depot project in Kanata – not stated anywhere else in the
OBC
•
A fire alarm system that does not fully comply with the OBC must be
upgraded/replaced if maglocks are to be installed (OBC – 95-28-448)
Installation and Application Issues
How much work can you do to a door
before the listing is void?
– Grey Area – reference NFPA 80, 1-3.4
Preparation of fire door assemblies for locks, latches,
hinges, remotely operated or remotely monitored
hardware, concealed closers, glass lights, vision panels,
louvers, and astragals, and the application of plant-ons
and laminated overlays shall be performed in
accordance with the manufacturer’s inspection service
procedure and under label service. (See Appendix F and
Appendix G.)
Installation and Application Issues
How much work can you do to a door before the
listing is void?
– Grey Area – reference NFPA 80, 1-3.4
Exception: For job site preparation of surface-applied hardware,
function holes for mortise locks, and holes for labelled viewers, a
maximum 3/4-in. (19-mm) wood and composite door
undercutting, and protection plates (see 2-4.5) shall be permitted.
Surface-applied hardware is applied to the face of a door without
removing material from the door other than drilling round holes
through the face of the door to accommodate cylinders, spindles,
similar operational elements, and through-bolts. The holes shall
not be permitted to exceed a diameter of 1 in. (25.4 mm) with the
exception of cylinders.
Installation and Application Issues
• Generally, all doors have to be listed to accept
specific hardware
• It MUST be looked at as a door opening system - not
individual pieces
• If you core drill through a door to run some power
wiring – the listing is, in most cases, void.
• Ask for a copy of the manufacturer’s
literature/correspondence clearly indicating that the
affected door is listed to have the identified
hardware and security devices installed.
Installation and Application Issues
Immediate release on fire alarm – processing can take up to 20
seconds in some instances – new ULC standard – no more than
5 seconds
MPS with dual contacts – for immediate release
Single switch for manual release and manual reset – BMEC rulings
have allowed a second switch but the “required” switch must
take precedence
ANYBODY can work on a security system from ANYWHERE – IP
enabled – this is a MAJOR risk factor affecting reliability and
life safety – Certification is the way to go
Installation and Application Issues
• Group maglocks to area of coverage for each
transponder otherwise will have release issues
during stand alone/degrade modes of operation –
test for this!
• Try to match security controller area of coverage to
fire alarm transponders – need for unified approach
• Can’t use an addressable relay – does not fail safe –
stays in position it was in before power failure – be
specific – some manufacturers can now program a
particular relay to operate in this manner – test for
this!
Installation and Application Issues
• Unplugging of power supplies for security systems –
will reset when power re-introduced – not per Code
• Supervising of release relay
• MPS at barrier free height if barrier free path of travel
• Need CFAA trained technician for MPS installation
to maglock
Installation and Application Issues
• Issues of differing voltages of maglock controllers –
fire alarm is always 24VDC
• Release on first stage of FAS operation
– even if first stage is silent operation.
– OBC allows release on second stage for care or
detention occupancies.
• All MAGLOCKS in entire complex to be released on
any alarm (NBC allows release based on area of
coverage of transponder).
• Degree of testing during the approval stage varies
Installation and Application Issues
• Fire alarm loss of power: If no batteries and
breaker turned off – generator does not start and
fire alarm does not work and maglocks do not
release.
• Blue manual pull stations – if red one is there
too it is allowed (via Code silence) but is VERY
confusing.
• Supervising circuit from fire alarm to security
controller – release on fault in circuit – normally
not electrically supervised unless addressable
relay
Installation and Application Issues
• Bypass switch allowed in OBC however a system trouble
(visual and audible) has to be initiated and the trouble
signal has to be sent to the monitoring station.
– Issue: if a monitoring system is not otherwise required – does this clause
require one? Some say “yes” and others “no” – my opinion is it should be
“yes”
• Emergency lighting at the doors – Code does not
reference what level of lighting is required
– a performance based approach is typically taken
– “can you read the sign on the door?”
• Electromagnetic locking systems are anything but a
“system” unless you follow the HRSDC approach.
Maglocks are always patched together.
Installation and Application Issues
• Maglocks are NOT to be reset after releasing from a
power loss when the 120VAC (or power) is re-established.
Only the reset switch can reset the maglocks
• Maglocks are not to be re-energised via re-setting for the
fire alarm system after having been released by the fire
alarm system. Only the reset switch can reset the
maglocks
• Maglocks are not permitted to be re-set locally by a local
re-set switch, after any type of release. Only the reset
switch can reset the maglocks

The Wrap Up
• Do your homework, be thorough, challenge the
professionals and ensure safety.
• Ask for test records and certification documents.
• Check for ULC or other regulatory labels on all
equipment.
• You are also a guardian of the public trust – review and
test maglock systems with this in mind.
• Maintenance? Not in the Ontario Fire Code.
