Setting the Data Bus Address and Enrolling Device(s) into the System
All devices that operate on the RS-485 4-wire data bus must have a unique address setting from 1 to 16 within their device TYPE.
Keypads and Access Modules are device TYPE 1, input (zone) expanders TYPE 2, output expanders TYPE 3, etc. The purpose of device
types is so that the address numbers can be re-used in each different device type. It is OK to have a Keypad, a Zone Expander, and a
Output Expander all set to address 2 and on the same data bus since each device is a different device type. It is NOT OK to have
duplications of addresses within the same device type. I.E. Multiple keypads on the same control cannot be set to 'like' addresses.
Setting the Data Bus Address of the M1KAM Access Module: The address setting is very important because it establishes the Zone
ID of the Door Status Input AND the Output ID of the on-board relay that is used to operate the locking device. Refer to Table 1 below.
Since the Access Module is the same device "type" as a Keypad, its bus address must be unique among any of the possible 16 keypad
addresses. If more than 1 Keypad or Access Module is installed, each one MUST be set to a unique address (2, 3, etc). The maxi-
mum number of keypad addresses is 16. Duplicate addresses MUST NOT EXIST. I.E. Multiple keypads and/or Access Modules must
each have a unique address.
1. There are 4 white switches located in the top right hand corner of the M1KAM board. Each switch has a position of OFF or ON
(binary value 0 or 1) and a decimal equivalent value of (1, 2, 4, or 8). The total decimal value of the "ON" switches equates to the data
bus address.
2. Proceed to the ENROLLING process to make the Access Module operational.

Jumper Settings for RTE (Request to Exit) &
DHO (Door Held Open) Times
NOTE: Jumper JP1 located in the middle left
side of the board is used to engage a 120
Ohm resistor for terminating the M1 Data
Bus. Please see Data bus wiring
instructions before using this jumper.

Enrolling the M1KAM with the control: Once the address is set and the M1KAM powered up it will be necessary to manually ENROLL
the new device so that the M1 Control knows it is present. This is accomplished either from keypad programming "Menu 1 - Bus
Module Enrollement" or from the NessRP Remote Programming Software. Proceed to the ENROLLING process to enroll the device
and make it operational.
(This step requires an LCD Keypad or the ElkRP software)
1. Press the ELK key, then press 9 (or scroll up) to display 9 - Installation Programming. Press the
RIGHT arrow key to select this menu. The Installer Program Code (PIN) must be entered to access
this menu.
2. Enter the Installer Program Code. (See M1 Manual for the default Code)
3. The first Installer Programming menu displayed will be "Bus Module Enrollment"
4. Press the RIGHT arrow key to select this menu. "Enrolling Bus Modules" will display
5. The M1 will transmit an enrollment message to all data bus devices, following by a display showing the
total Bus Modules that are enrolled. To view the enrolled devices and/or remove a device press the
RIGHT arrow key to select Edit mode.
6. Press the * or Exit keys to exit Installer Programming.

Jumper Settings for RTE and DHO Time Values
The M1KAM has four possible jumper settings that adjusts the amount of time on the Request To Exit (RTE) and Door Held Open
(DHO) features. The time values for RTE and DHO are adjusted together. See Table 1 for the time adjustments.
Request To Exit (RTE) refers to the amount of time that the Door Lock will remain Unlocked by the action of the RTE device.
Door Held Open (DHO) refers to the amount of "Delay" time the door status may remain open before the Out1 Alrm output becomes
active. The timer starts upon a valid access, when a RTE occurs, and/or when the IN2DR input (door status) is tripped. The Out1
Alrm can be connected to activate a relay or a low current sounder device as a local alert. The output stays on until the door is
physically restored to a closed/secure state.
