Step 1. Preparing to Install the KT-300
KT-300
KT-300
KT-300
KT-300
(
Required to install the KT-300:
- KT-300 controller with accessory kit
- AC transformer 120 / 220 VAC/16 VAC, 40 VA,
class 2 *
- One 12 volt battery 7A/h *
- Ground clamp *
A visual verification should be made when unpacking the KT-
300. Any missing item/part or damaged component should be
reported immediately.
*Not included
Step 2. Physical Installation
(
Check for ideal indoor location
(
Stay away from electrical or communication
devices
The KT-300 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 (elec-
trical 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 levels, 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 meters (6
feet) from any high voltage equipment or wiring and from electrical
equipment susceptible of generating electrical interference; at a
minimum distance of 1 meter (3 feet) from telephone equipment or
lines; and at a minimum of 8 meters (25 feet) from any transmitting
equipment.
Physical access, using keys, on controlled doors must be pro-
vided so that the KT-300 can easily be accessed for servicing
purposes in case of malfunctions.
Step 3. Power Requirements
(
DO NOT POWER AT THIS POINT!
(
Install 120 / 220VAC/16VAC, 40VA, class 2 transformer
(
Place battery in cabinet
(
DO NOT POWER AT THIS POINT!
The KT-300 controller must be powered by a 16VAC/40VA class
2 wire-in or plug-in transformer.
Power should only be applied to the unit when all connections are
completed and tested.
If the AC supply is removed, the backup 12 volt gel type of 7 Amp/
hour battery (if fully charged) will support normal operation for up
to 12 hours. An internal battery verification will cut the battery
power if the battery voltage level falls below 9.5 volt.
Note: The KT-300 unit will not start on battery alone.
Step 4. Earth Grounding
(
AWG#18 grounding wire to EGND
Since the KT-300 uses high performance communications, proper
grounding must be provided to ensure proper operation. An
AWG#18 single conductor solid copper wire must be used to
ground each controller to a good earth ground as per the local
electrical code (be careful of ground loops). The ground clamp
should be located below any other ground.
It is also recommended to install an AWG#18 single conductor
copper wire between each controller.
