Controller Installation
Site Plan
The first step to a successful installation is to make a site plan. This is a drawing
indicating the location of each component of the access system. It should include the
controllers, power supplies, PC, card readers and/or keypads, door contacts, door strike
sensors, all alarm points and all wiring lengths. Have the customer provide blueprints of the
building or buildings to assist you with this task. It is very helpful to have access to the electrical
drawings as well. Always remember to have your site plans approved by the local
regulatory agency to assure that your installation will conform to all safety codes. When
drawing any site plan, keep the following items in mind:
1. Keep all wire (power, network, strike, door sensor, alarm and reader) well away from high
frequency and high power lines. If the crossing of these lines is unavoidable, do so at a 90degree
angle. This minimizes the electrical interference, which could disrupt the system’s
normal operation.
2. Use 22 AWG (Beldon #9946) shielded wire for readers; 22 AWG shielded twisted pair for
controller to controller (loop) wiring (Beldon #8723); and 18 AWG shielded wire for door
release connections. All system wiring should be in dedicated conduit, with the shields
grounded at the controller end only.
3. The controller should be centrally located in reference to the doors and/or alarm points that
it controls. This will prevent many long wire runs. It should also be located in a secure area
to prevent tampering.
4. If the distance between networked controllers exceeds 1000 feet (at 9600 baud), line drivers
or short haul modems are required.
Installation Procedure
1. Mount chassis.
2. Wire network (J17).
3. Wire power supply (J17). DON’T PLUG IN AC AT THIS TIME.
4. Set Options, Unit No., and Baud Rate Switches on the CPU Board.
5. Connect the personal computer and modem if necessary.
6. Connect AC Power and make sure the three LEDs are illuminated.
7. Put Option Switch One in the down position.
