SPECIAL
PROJECTS

Casino with
short cabinet gate and break box assembly beside door. Need the
gate always locked w/ high security
lock, and remote release of the gate. Installing the electric strike
was a challenge, but it came out working well and looking good.

Dementia care facility
with the goal to bring them into compliance with
fire and life safety code. Mag locks with a 15 second delayed
release timer and alarm with keypad by-pass met the goal. This
is a courtyard
gate never intended to have anything but a simple gate latch.
The alarm/timer unit is mounted inside the building.

CARD ACCESS
SYSTEMS & ACCESS CONTROL
Card access systems have gone from high security military and government installations
to common office buildings, security gates, and even private mailbox drops.
The basic parts to a card access system are as follows: electric release of
the door (either electric lock or strike), controller that holds the programming,
reader to read the card’s ID, and the card it’s self.
a) Electric release/control of the door. The
controller needs a way to release the door, this is done electronically through
an electric strike that works with a mechanical lock, or an electrified lock
that could be a lock with a solenoid or a magnetic lock. The security of
the building hinges on this aspect, if the mechanical lock or electrification
is easily by-passed, then there is no point in the rest of the system. This
is why we recommend quality locks and electric strikes to attain a high level
of security. Additionally it’s important to have a door closer on the
door so that it will close after a valid entry. The door can also be monitored
by the system and initiate some sort of alarm (sounder, light, or pop-up
screen on a computer) if the door is “propped open” (past a certain
time limit that can be choosen), or if the door is “forced opened” (opened
even though the controller did not signal it to open, the lock/door has been
by-passed or someone may have used a key).
b) Controller. The controller is a micro-processor
with programming and memory. The programming may be performed through
a keypad, or with a PDA, notebook, or a desktop. The programming is
used to add & delete card holders, set schedules to control card
holder access by day, time and even holiday. The programming also can
set limits on propped doors, routing alarms for various situations.
The card holder data base may also hold various other data at the owner’s
discretion (Car type/color/license, birthdates, departments, home phone
numbers, etc.) that could be pulled up by security to confirm the card
holder, or in other ways. Controllers today have non-volatile memory
and retain programming in the event of a power outage.
c) Reader & card/credential. The reader
depends on the chosen technology. The various technologies are magnetic
stripe (un-secure), mag stripe with Wigand technology, Proximity (where
the card is read at a distance from the reader), Smart card (similar
to prox but more secure, storing biometric data, user defined formats,
etc.), and multi-technology combining multiple formats. Instead of
cards, there are key-fobs that can do the same function, but smaller
and more durable. Readers can also be keypads, biometric (fingerprint,
hand print, retinal etc.), or a combination of these. The data from
the reader is encoded and transmitted to the controller.

STAND
ALONE SYSTEMS
With rapid
advances in technology today, many features of access control systems
can be incorporated into a stand alone system, or they can be simple
one-code mechanical units.
Stand alone access control locks are available in a variety of technologies
(keypad, prox card, mag stripe cards), and variety of formats (mortise, cylindrical,
deadbolt, etc.). Electronic versions may be programmed through the keypad on
the unit, with a PDA or similar device, on a WiFi network, or by plugging a
notebook computer into the unit. The addition or deletion of users, changing
access times/days, and downloading events, are all functions that can be performed.
Stand alone may be a good solution for some situations. Please call for a consultation.

REMOTE RELEASE
A remote release would be a button at a desk to release a door so visitors
can enter. This would be the most basic access control, with the computer being
replaced by the brain of a human. The button would power up an electric strike
or electrified lock to release. They can be economical systems.
Please call for a consultation.
INTERCOM SYSTEMS
Intercom systems have come a long way with today’s technology. Video
intercom systems are now economical. For multi-family housing, the main unit
can dial phone numbers preset into the unit. So with cell phones, you could
call the person and they could let you in, even if they aren’t even in
the same city.
The intercom is attached to a electric strike or electrified lock that releases
when powered up.

DELAYED EGRESS
Delayed egress is a system used by retail/mall type stores or in dementia care
facilities. The system is defined by an electronic lock that will hold the
door locked for 15 seconds while the alarm sounds after activations.
For example, once the exit bar is pushed for more than a couple seconds, the
alarm sounds and an irrevocable count-down begins. After 15 seconds, the door
can be opened. In the event of a fire alarm or loss of power, the unit unlocks
immediately. In retail these units are used for loss prevention from shop-lifters.
In dementia care facilities, these units allow the staff to try to keep residents
from leaving the facility un-supervised.
Delayed egress units can be an exit device, or magnetic lock with whatever
door hardware exists. They need to be powered and require special power supplies
in some cases, they can be connected to a variety of alarm systems, lights,
buzzers, etc. they must be connected to the fire alarm system for the building.
There are a variety of options for authorized use without the alarm, keypads
or key switches can be integrated or even an access control system.
