Elk specifications INSTALLATION OF ELK-M1KPAS KEYPAD ARMING STATION

INSTALLATION OF ELK-M1KPAS KEYPAD ARMING STATION

The M1KPAS mounts into a standard electrical box. Depending upon local/state regulations it may be permissible to mount an M1KAS alongside other electrical devices provided that a special low voltage divider insert and/or low voltage combo box is utlized. Select a location with an ambient temperature range between 32° and 120° F (0° to +49° C). Avoid direct sunlight if possible. CAT5 or CAT6 wire (4 pair, 8 conductor) is highly recommended for all data bus cables and the extra wires may be required for data return paths where multiple homeruns or devices are installed. NOTE: Please refer to the M1 or EZ8 Installation Manual for important information about Data Bus termination when multiple homerun cables are installed. Minimum conductor size is 22 or 24 gauge. Maximum resistance per wire is 25 Ohms. Device placement beyond 1000' is not recommended. DO NOT SPLICE OR CONNECT WIRES WITH THE CONTROL POWER ON.

1.Turn off all power to the control.

2.Splice the Black, Red, White, and Green wires of the 4-wire cable assembly to the data bus wires. Plug the connector onto the back of the M1KPAS. Tuck the wires and splices neatly into electrical box.

3.Fasten the top and bottom mounting ears to the electrical box using flat head #6 machine screws.

4.Turn on the power to the control. One or more of the lights on the M1KAS may be illuminated indicating the unit has power, however it will not become operation until it has been assigned an address and has been enrolled into the Control. See steps on next page.

DATA BUS TERMINATION IS VERY IMPORTANT!!

Ideal setup is 2 home run cables with daisy chained devices. The last device on each cable MUST have a terminating resistor installed (activated) via the 2 pin header/jumpers marked JP1 on M1KPAS & M1KP2 Keypads and expanders, JP2 on M1KP Keypads. Place a black shorting cap from hardware pack onto the 2 pins to install a 120 Ohm resistor across data lines A & B. NOTE: Place a shorting cap on JP3 of Main Board if there is only 1 data bus cable. See diagrams on multiple cables.

WARNING! The RS485 Data Bus must NEVER have more that 2 terminating resistors header/jumpers installed.

Reliability and response will be negatively affected!

Diagram for Daisy Chain Connection of Data Bus Devices Using Two (2) Home Run Cables

The ideal way to connect multiple home run cables is with an ELK-M1DBH Data Bus Hub. It accepts CAT5 or CAT6 cable with RJ45 plugs on the ends.

It does all the work of series connecting the DATA lines A & B and provides a clean, organized management of the data bus wires.
