Door closer.
A standard hydraulic door closer is almost
mandatory to insure that the door closes automatically after an
entry and to prevent “door open too long” or “door left open”
alarms.
Door contact.
When the door is locked, the access
controller supervises the door contact and will report a “door
forced open” alarm if the door is opened without the use of a
card. When the door is unlocked, the condition of the door
contact is still supervised but no alarms are generated.
Exit detector and exit button.
The exit detector or
button will warn the system of the pending opening of a free
exit door by a user leaving the protected area.
Local door alarm.
The local door alarm is integrated in the
IoProx Door Reader for outside and in the T-Rex for inside. It
provides audible indication of an abnormal condition. The most
common conditions to be reported locally are “door forced
open” and “door open too long” events.
Reader and keypad.
A keypad only installation is
considered less secure than a reader only installation. Adding a
keypad to a reader significantly increases the level of security.
Step 5•
Connecting the Door Locking Device
The lock NC, NO and +12VDC terminals are located on the top
left of the KT-100 Controller terminal strip.
The locking device output is controlled by the software
according to preset parameters for allowing access or unlocking
doors according to schedules and access levels.
The NO or NC output can operate DC powered locking devices
such as electromechanical strikes and can be configured to
operate in fail-safe or fail-secure modes (normal or reverse
action). The maximum permitted current is 250mA @ 12VDC
per output.
NOTE:
Use 1K ohm end-of line resistor b12VDC and
NC if not used. This resistor is already included in the box (KT-
100-ACC).
To connect the door locking device:
1.
Connect the negative wire from the door strike to the NO
output and optionally, the door magnetic lock to the NC
output.
2.
Connect the positive wire to the +12 VDC output.
WARNING!
Controlled door locks may be governed by
regulatory bodies and should always be installed
according to local regulations. In most instances, there
are strict limitations to installing fail-secure devices
and fail-safe locking devices such as magnetic locks or
other similar locking devices on doors used as
emergency exits.
Step 6•
Hooking up Inputs
The KT-100 has an on-board capability of monitoring 4 input
zones. Each input is supervised with or without end-of-line
resistors (5.6K ohm). The maximum distance of one line is 600
m (2,000 feet) with AWG#22 (Kantech part #CBL-R2).
By default, inputs 1-2 are reserved for the door contact and the
request to exit. The door contact is assigned to input 1 (Z1) and
the associated request-to-exit detector to input 2 (Z2). There is
no obligation to follow these rules but such a standard
convention makes it easier for servicing.
