Limited
Access Control System
The
M1 Cross Platform ControlÒ can be used as a limited or small access
control system. The control
can accommodate up to 199 users (requires firmware version 4.4.2 or
later and ElkRP version 1.6.8 or later) and 16 keypads. This newsletter will
cover some examples of how the M1 can be used for access control.
One
26 bit Wiegand proximity reader or keypad can be installed for each M1
keypad on the system. The ELK-M1PR
is an internal proximity reader that permits touchless
reading of M1PRC proximity cards and M1PRF proximity fobs. These
cards and fobs are designed for use with the M1PR.
If an external proximity reader is used, use the cards and fobs
designed for that particular device.
Application
Note: When
using an external
proximity reader with proximity cards,
considering the placement of the reader can offer the user added convenience.
The ideal height for the reader is approximately 36 inches.
At this height, the user can keep the card in a wallet or outside pocket
of a purse, and the card can be read without the need to remove it from
the purse or wallet.
Proximity
cards and fobs are enrolled into a User Code location using the same
procedures used to add/change User Code PINs.
- Access User Menu 6-Change User Codes.
A master user code will be required to access this menu.
- Enter the three digit number of the desired User
Code location (001 – 099) or use the UP or Down arrows to scroll
through the codes. Then
select CHG by pressing the RIGHT arrow key.
The keypad will display any existing 4 or 6 digit code that
is programmed for that user, along with any programmed name.
- Place a new (not previously enrolled) prox card
or fob near the proximity reader.
If the code is accepted the Keypad will beep 3 times and
display the 12 digit ID for that card/fob.
If
a card/fob is rejected, the keypad will emit a low error tone and
display “Code Not Authorized, Redo.”
Ensure that the card/fob has not already been enrolled in a
different User Code location and that the card/fob is designed for use
with the proximity reader.
Each
user can be given user authorizations that determine what that user is
allowed to do. This is done
in RP under each user, or can be setup through the keypad using Menu 2
under Installation Programming Menu 9.
These authorizations include Arm, Disarm, Bypass, Access,
Temporary Code, Master, User Menu 1-5 Allowed, and Duress.
The Access authorization allows the code to activate the Access
Keypad Events 1313-1328 for the keypad where the code was entered.
The Whenever/And/Then Rules engine is used to program what occurs
when the event is activated.
The
diagram below shows how an ELK-924
can be connected to Output 7 to switch 24V to a door strike.

The rule below will activate Output 7 for 10
seconds when access is activated on Keypad 1.
This will cause the door strike to be tripped, allowing the user
to open the door and enter the premises
WHENEVER ACCESS Keypad 01(KP1) IS TRIGGERED
THEN TURN Door Strike (Out 7) ON FOR 10 SECS |
By adding the
AND statements shown in bold, the user will only be able to gain access
between
7:30 am
and
6:30 pm
.

WHENEVER
ACCESS Keypad 01(KP1) IS TRIGGERED
AND
TIME OF DAY IS LATER THAN
7:29
AM
AND
TIME OF DAY IS EARLIER
THAN
6:31
PM
THEN
TURN Door Strike (Out 7) ON FOR 10 SECS |
To
give the user audible notification that the code was accepted, a
miscellaneous voice message can be used.
In this example, Miscellaneous 4 (vm242) is programmed with the
phrase “Access Authorized.” By
adding the THEN statement shown in bold, the system will announce this
message each time a valid access code is entered.

WHENEVER
ACCESS Keypad 01(KP1) IS TRIGGERED
THEN TURN Door Strike (Out 7) ON FOR 10 SECS
THEN
ANNOUNCE Miscellaneous 4 (vm242)

The History Log stores the most recent system activity.
This can be used as a means of tracking when a user code is used
for access. This log includes
the user name or number, the date and time the code was used, and the area
and keypad where the code was entered.
To view the log in ElkRP, click the log button in the toolbar.
You can choose to view 20 events at a time or receive the entire
log. The log can be printed
from this screen or by choosing print from the file menu, and then
selecting ElkRP log. To view
the log from the keypad, access user menu 4. The newest event will appear
first. Use the up or down
arrow keys to scroll through the log.

Tip

Modem
Connection Methods
Customer
Will Force System To Answer
In this mode, ElkRP calls the system and someone with access to the system
is responsible for making it answer. The
telephone number that ElkRP dials is located on the Account Details
screen.
The customer or on-site installer has to be expecting the call.
ElkRP dials the number. When
the customer’s telephone rings, the person on-site uses the keypad to
force the system to answer the call. The
details of how to do this differ from one system to the next.
Refer to the system’s instruction manual for specific
information. After the system
answers, ElkRP connects to it.
The
advantages to using this method are that it is very reliable because, if
the person on-site answers on the first ring, it eliminates the
possibility of an answering machine or some other device answering first.
It also provides security, because someone with access to the
system must be present to allow a connection (thus the system’s
auto-answer feature may be disabled if this method is the only method
used).
A
disadvantage to using this method is that it is not automatic.
It requires human intervention on the system’s side, and the
person must be expecting the call.
