ELK-M1KAM — Single Door Access Module Installation Manual

Installation manual for the ELK-M1KAM Single Door Access Module — a single-door access interface for the M1 and M1EZ8 control panels, connecting to the 4-wire keypad data bus with support for 26-bit Wiegand and Dallas "One-Wire" iButton readers.

Application

The M1KAM is a single door access interface module for use on M1 and M1EZ8 control panels. It connects to the 4-wire keypad data bus in place of a traditional M1 keypad. Since the maximum number of keypads on an M1/M1EZ8 is 16, the maximum number of M1KAM modules (and controlled doors) is 16 minus any installed keypads. The M1KAM includes a Form "C" dry contact relay (door unlock) output compatible with most door lock devices regardless of voltage rating or style (AC/DC), accepts 26-bit Wiegand card/proximity readers, and also accepts Dallas "One-Wire" iButton readers/devices. It includes additional inputs (request-to-exit and door contact, both supervised with a 2,200 ohm EOL resistor) and outputs (Door Held Open Alarm, System Ready to Arm, System Armed — all switched negative).

Features

• Input for a 26-bit Wiegand reader
• Input for a Dallas "One-Wire" iButton reader
• Heavy duty Form "C" relay contacts for switching door strike power
• Low current (50mA) switched negative output for Door Held Open alarm
• Low current (10mA) switched negative outputs for System Ready to Arm and System Armed
• Supervised inputs for RTE (Request to Exit) and Door Status sensor
• Installs in place of an M1 keypad on the RS-485 4-wire keypad data bus
• Four selectable time settings for Request to Exit and Door Held Open
• Hardware watchdog circuit

Specifications

• Connections: Unpluggable screw terminals, 16 position
• Operating Voltage: 13.8 VDC
• Current Draw: Less than 30mA min. activity, 44mA fully active
• Housing Dimensions: 4.25" x 6.375" x 2.125"
• Circuit Board Dimensions: 3.95" W x 2.875" H x 0.95" D

Installation

Mount the M1KAM within 25ft of the door being controlled (or wherever convenient along the data bus, up to its max distance). Ambient temperature 32°-120°F (0°-49°C). CAT5/CAT6 (4 pair, 8 conductor) is recommended for data bus cabling. Min. conductor size 22-24 gauge; max resistance per wire 25 Ohms. Do not splice or connect wires with control power on.

1. Turn off all power on the M1/M1EZ8 before wiring.
2. Connect the 4-wire data bus (+12V, Data A, Data B, Neg) from the M1/EZ8 to the identically marked M1 DATA BUS terminals on the M1KAM (unpluggable terminal blocks).
3. Install a separate local power supply for the locking device (door strike or mag lock). Never power an electric door strike or mag lock from the +12VDC of the M1/EZ8 data bus.
4. Wire the Relay (Output): for a "Fail Safe" locking device (unlocks when power removed), connect to the RELAY N/C terminal; for "Fail Secure" (stays locked until power applied), connect to RELAY N/O. A general purpose blocking diode (supplied) MUST be installed on door strikes across the +/- connections to stop voltage kickback. The M1KAM requires a Whenever/And/Then Rule (via ElkRP) to energize the relay when a valid credential is read.
5. Install a proximity reader (26-bit Wiegand) or Dallas iButton reader. Wiegand readers need a 4-wire connection (2 power, 2 data); iButton readers need only 2 wires (Black to READER NEG, White to READER iButton).
6. Install a Normally Closed (N/C) alarm contact on the door, wired to IN2DOOR and NEG with a 2,200 Ohm EOL resistor in series.
7. Install a Request to Exit (RTE) sensor/switch (typically required by law for free exit), wired to IN1 RTE and NEG with a 2,200 Ohm EOL resistor.
8. Three additional outputs: OUT1 ALARM (door held open too long, 50mA max), OUT2 READY (remote ready-to-arm indication, 10mA max), OUT3 ARM (remote armed indication, 10mA max) — all switched negative.
9. Power up the control, local power source, and reader, then proceed to setting the data bus address.

Setting the Data Bus Address

All devices on the RS-485 4-wire data bus must have a unique address (1-16) within their device type. Keypads and Access Modules are device TYPE 1, so an M1KAM's address must be unique among the 16 possible keypad/access-module addresses (duplicate addresses within the same device type are not allowed). Four white DIP switches (S1-S4, binary values 1/2/4/8) set the address, which also determines the Zone ID (door status input) and Output ID (relay).

Jumpers (S1/S2) also select RTE/DHO time values: 00 = 10s RTE / 20s DHO, 10 = 20s / 40s, 01 = 30s / 60s, 11 = 45s / 90s.

Enrolling the Module

1. Press the ELK key, then 9 (Installation Programming), then the RIGHT arrow. Enter the Installer Program Code.
2. The first menu is "Bus Module Enrollment" — press RIGHT arrow to select.
3. The M1 transmits an enrollment message and displays the total enrolled bus modules.
4. Press * or Exit to leave Installer Programming.

Adding Access Credentials

Two methods: (A) enroll a card/fob via an attached M1 keypad with a built-in/external reader under Menu 6 - Change User Codes (present the credential when prompted; 3 beeps = accepted, error tone + "Code Not Authorized, Redo" = rejected due to duplicate code or incompatible facility code); or (B) enter the code string directly via the ElkRP Programming Software (the only method for Dallas iButtons, whose 12-digit code is printed on the button itself). After enrollment, set the credential's User Code Options (area/partition, Arm, Disarm, Access) in Menu 02 of Installer Level Programming.

Whenever/And/Then Rules

An Access event only logs by default — it takes no action unless a rule is written in ElkRP. Example: WHENEVER ACCESS 'Keypad Name' (KP 2) IS TRIGGERED THEN TURN Output 194 ON FOR 10 SECS — this could unlock a door strike for 10 seconds. Note: ElkRP always references the device as "KP" plus an address number, even for an M1KAM module.
