Installing the KT-315
Physical Installation
Check for ideal indoor location.
Stay away from electrical or communication devices.
The KT-315 Controller cabinet has been designed to be mounted on a wall without any additional enclosures. The cabinet is
large enough to accommodate the battery backup supply and the necessary wiring connections for most applications. EMT
(Electrical Metallic Tubing) conduit knockouts are provided in 2.2 cm (7/8”) on all sides of the cabinet.
The cabinet should be mounted indoors, in a secure location providing normal temperature and humidity, leaving 23 cm (8”)
clear space around all sides and a minimum of 33 cm (13”) clear space in front of the cabinet. The location should be easily
accessible for servicing the equipment and it is recommended that controllers be located close to the controlled doors.
Controllers must be located at a minimum distance of 2 m (6 feet) from any high voltage equipment or wiring and from electrical
equipment susceptible of generating electrical interference, at a minimum distance of 1 m (3 feet) from telephone equipment or
lines, and at a minimum of 8 m (25 feet) from any transmitting equipment.
Physical access, using keys, on controlled doors must be provided so that the KT-315 can easily be accessed for servicing in
case of malfunction.
Earth Grounding
AWG#18 grounding wire to EGND.
The KT-315 uses high performance communication, proper grounding must be provided to ensure proper operation.
Make an earth ground connection to the cabinet of the KT-315 as per the requirements of your local electrical code. Wire the E-
GND terminal on the KT-315 printed circuit board directly to that connection point.
Door Locking Devices
Connect door locks to + and LK1- (+ and L2-)
Maximum 250mA @ 12 VDC per output
Check for local “magnetic lock” regulations
LK1-, LK2- and + terminals are located on the bottom left to the KT-315
terminal strip. The locking device outputs are controlled according to the
end-user programmed parameters for allowing access to or unlocking
doors according to schedules and access levels. These door locking
device outputs can operate DC powered locking devices such as
electromechanical strikes and can be configured to operate fail-safe or
fail-secure (normal or reverse action). Maximum DC current for each lock
output is 250 mA.
NOTE:
Use 1K ohm EOL (End-Of-Line resistor) b and LK- if not
used. This resistor is already included within the controller
packaged box (KT-315ACC).
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.
For EN 50133-1 compliance, this equipment is designed to be used in an environment that meets a
maximum pollution degree of 2 and over voltages category II - NON HAZARDOUS LOCATIONS,
indoor only. The equipment is FIXED and PERMANENTLY CONNECTED. It must be installed in a
