ELK-AEKP Low Profile LCD Keypad — Installation Instructions

Installation instructions for the ELK-AEKP Low Profile LCD Keypad — a 32-character blue/white backlit keypad for the Elk E27 Alarm Engine, supporting proximity card readers for arming, disarming, or door strike control.

Application

The ELK-AEKP surface-mounts with or without a 1- or 2-gang electrical box, and can be flush-mounted using the separately purchased ELK-M1BBK2 back box kit. It accepts the Elk-106055 external proximity reader (26-bit Wiegand) — other brands of 26-bit readers may also be compatible.

Specifications

• Operates from the E27 "RS-485" data bus
• Operating voltage: 13.8 VDC
• Accepts external 26-bit Wiegand proximity reader (optional)
• Input for 1 supervised zone
• One programmable "switched positive" voltage output
• Surface mounts with 1 or 2 gang electrical box; optional flush mount kit ELK-M1BBK2
• Size: 4.658"W x 5.5"H x 0.95"D (0.375"D if recessed)
• Color: White

Installation Instructions

Before making any wiring connections, turn the E27 Master Power Switch OFF.

• Ideal mounting height: 50-58 inches above the floor, away from direct sunlight, ambient temperature 32°F to 120°F (0° to +49°C).
• CAT5 or CAT6 (4-pair, 8-conductor) cable is highly recommended for all data bus cabling — extra conductors may be needed for data return paths on multi-home-run installations. Minimum conductor size is 22 or 24 gauge; maximum resistance per wire is 25 Ohms. Device placement beyond 1000 ft is not recommended.
• Refer to the E27 Installation Manual for data bus termination requirements when multiple home-run cables are used.

1. Fasten the mounting plate to the electrical box (or directly to the wall) using flat-head screws to avoid shorting the back of the circuit board.
2. Splice the Black, Red, White, and Green wires of the plug-in connector to the data bus cable. Plug the connector into the keypad, tuck wires neatly into the back plate, and install the keypad using the provided #4 plastite screws. Snap on the picture-frame trim ring with the notched edge facing down.

Wiring Reference

Splice the data bus cable to the keypad assembly using ELK-9002 "B" Connectors. An optional zone input (e.g. for an LED or relay, 50mA max) connects between the Blue and Black wires; an optional programmable output connects between the Brown and Black wires.

External Proximity Reader (Optional)

An ELK-106055 external prox reader can connect via an ELK-W039A 2-wire cable assembly (purchased separately): splice the reader's Green (Data 0) and White (Data 1) wires as indicated, and plug the cable into connector J2. Some other brands of 26-bit Wiegand-compatible readers may also work.

Please refer to the ElkConnect app instructions for details on enrolling the AEKP into the E27 system.
