INSTALLING THE ELK-M1KAM
Mount the M1KAM within 10 Metres of the door being controlled. Since It connects to the 4-wire keypad data bus the M1KAM can be
located from the control up to the maximum distance of the data bus. The location should have an ambient temperature range
between 0
°
to 49
°
C (32° to +120
°
F). CAT5 or CAT6 wire (4 pair, 8 conductor) is recommended for all data bus cables as the spare
wires may be required for data return paths where multiple homeruns or devices are installed. NOTE: Refer to the M1 or EZ8 Installa-
tion Manual for information about Data Bus termination when multiple homerun cables are installed. Recommended min. conductor
size is 22 or 24 gauge. Maximum resistance per wire is 25 Ohms. DO NOT SPLICE OR CONNECT WIRES WITH THE CONTROL POWER
ON.
Wiring Connections:
1. Turn OFF all power on the M1 or M1EZ8 Control before making any wiring connections.
2. Connect the 4-wire data bus +12V , Data A , Data B , and Neg wires coming from the M1 or EZ8 to the identically marked terminals labeled
M1 DATA BUS on the M1KAM. NOTE: The M1KAM features unpluggable terminals blocks for ease and installation and service.
3. Install a separate local power supply for the locking device (door strike or mag lock).
NEVER attempt to power an electric door strike or mag lock from the +12VDC of the M1/EZ8 Data Bus.
4. The Relay (Output) on the M1KAM operates as an On/Off switch between the locking device and the power source. Depending on how
the wiring is connected the voltage to the locking device can either be "turned On" or "turned off" when the Relay (Output) becomes
energized. Connect the wires in one of the following manners:
Cut one of the two wires leading from the power source to the locking device. Strip and connect one end to the RELAY COM terminal.
N/C - If the locking device is "Fail Safe" (unlocks when power removed), connect the other end of the wire to the RELAY N/C terminal.
N/O - If the locking device is "Fail Secure (stays locked until power applied), connect the other end of the wire to the RELAY N/O terminal.
Important points to follow:
1) A general purpose blocking diode (supplied) MUST BE INSTALLED on Door Strikes (at the strike) across the + and - connections
as shown in the hookup diagram. This helps stop voltage kickback 'transient' when the strike coil releases.
2) The M1KAM requires a Whenever/And/Then Rule to be written using the NessRP software. The rule instructs the Relay (Output)
on a specific M1KAM module to energize when a valid access credential (card, fob is read. See page 5 for an example of an M1
Access Rule.
3) The Output ID (Identification) of the Relay (Output) on the M1KAM is based on the Data Bus Address of the M1KAM. See Table 1
under "Setting the Data Bus Address" for more details.
5. Install a proximity reader ("26 BIT" Wiegand compatible) reader and connect it to the M1KAM as follows:
- 26 Bit Wiegand Reader - Requires a 4 wire connection, 2 for power and 2 for data to the M1KAM. Ideally the reader should be powered
from the local power supply being used for the locking device. It is important for the Negative (-) sides of both power sources (M1/EZ8
Data bus power and local power supply) to be commonly connected. See wiring diagram.
* Some readers have LED indicators for features like status, armed, ready, etc. It may be possible to connect and utilize these with
the M1KAM. See step 8 and the wiring diagram or contact Ness Technical Support for details.
6. Install a Normally Closed (N/C) alarm contact on the door. Connect this to the M1KAM using a two conductor wire. One wire connects
to the terminal marked IN2DOOR , the other connects to one of the terminals marked NEG . Install a 2,200 Ohm end of line (EOL) resistor
(provided) in series with the switch. There are two (2) NEG terminals on the M1KAM. See wiring diagram on opposite page.
Important point to remember:
1) The Zone number (ID) associated with the IN2 DOOR (door status) input on the M1KAM is based on the Data Bus Address of the
M1KAM. See Table 1 under "Setting the Data Bus Address" for more details. From the control panel programming this same input
ID can be defined as a Burglar alarm zone, allowing the door switch to be used for both the alarm and the Access Module.
7. Install a Request to Exit ( RTE) sensor or switch. This is generally required by law to allow free exit from the building. The output from
an RTE device is typcially the same as a two wire N/C door switch. One wire connects to the terminal marked IN1 RTE , the other connects
to one of the two terminals marked NEG . Install a 2,200 Ohm end of line (EOL) resistor (provided) in series with the switch. There are
two (2) NEG terminals on the M1KAM. See wiring diagram on opposite page.
8. There are three (3) additional Outputs on the M1KAM. OUT1 ALARM is designed to allow a local alarm if the door is held open too long.
OUT2 READY is a remote Ready To Arm indication of the Area or partition which the M1KAM is assigned. OUT3 ARM is a remote Armed
indication of the Area or partition which the M1KAM is assigned. Each of these outputs is 12 VDC low current (50mA.), switched negative.
See wiring diagram on opposite page. Be carefully to NOT EXCEED the maximum drive current of each output.
9. Turn on the power to the control along with the local power source for the locking device and reader. Proceed to the section titled "Setting
the Data Bus Address and Enrolling Data Bus Modules".
