Build A Customizable Security and Automation System

Create a powerful, fully customizable security and automation system with the ELK E27 Alarm Engine System Kit with Plastic Enclosure! This starter security kit includes the E27CB Control Board, AEKP Keypad, P1426 Power Supply, 73 Speaker, and SWB14P Plastic Enclosure. The E27 control board is the brains and heart of the ELK 27 security and automation control system, providing the foundation for a hybrid hardwired and wireless network of sensors and devices to monitor, protect, and automate your home or business. The E27 supports up to 128 hardwired, wireless, or hybrid zones, all of which can be partitioned into 8 security areas. The E27 features 16 on-board wired zones and if connected to additional E27 Alarm Engines, the number of wired zones can be expanded up to 128. Onboard alarm inputs include one form C relay and one 10V (12VDC, 50mA). The system's open connectivity platform allows integration with Elk's 50+ partners, offering a seamlessly interconnected system with control over Security, Energy Management, Lighting, and more into a single, robust system.

The ELK27 Alarm Engine is a scalable home security and automation solution for any sized installation. Out of the box, the ELK27 Alarm Engine Main Board supports 16 on-board wired zones, two 12VDC Power Outputs, 10 programmable outputs, one programmable Form "C" Relay output, two supervised 4 to 8 ohm alarm outputs, one RS485 Data Bus, and two power supply options. To add wireless inputs from 319.5MHz or Z-Wave devices, additional zone inputs, outputs, or relays, their corresponding add-on modules must be purchased separately.

The ELK-AERF3 and the ELK-AERF9 allows the E27 to communicate with ELK 319.5 and two-way wireless sensors respectively, up to 128 sensors and 16 keychain remotes in total. The ELK-AEWF Wi-Fi Adapter increases the operational reach of a single system in installations where Ethernet connections are not possible. The ELK-AEZW Z-Wave module adds up to 80 Z-Wave Plus devices to the Elk network. The Z-Wave Module does not add new zones to the ELK 27 network; any connected Z-Wave Plus device uses an available wireless zone. The ELK-AEXDD Alarm Engine Digital Dialer connects the E27 to a Central Monitoring Station using a standard landline telephone or cellular device.

The ELK 27 Alarm Engine is a user-friendly system that can control virtually any security or automation device in homes or businesses. It sports a powerful new engine with AND, OR & ELSE logic that enables complex security or automation scenes and immediate responses to triggered devices or preprogrammed routines. Configuring automated routines is made easy with easy to understand text based references.

The ELK-AEKP Low Profile LCD Keypad features a 32 character blue/white backlit display, blue lighted keys, 4 programmable function keys, and the ELK menu navigation keys. It may also be flush mounted using a back box kit (ELK-M1BBK2, sold separately). The AEKP is compatible with external 26 bit Wiegand compatible proximity readers, allowing RFID cards or keyfobs to be used for various security functions (arming, disarming,door strike control, etc.)

The ELK-73 is a 20 Watt, 8 Ohm Speaker mounted in an attractive surface mount plastic enclosure. Sound "echoes" off the mounting surface from the back plate edge. This unique contemporary speaker has a smooth, paintable, "no grill" surface that easily blends with any décor. This speaker mounts to any flat surface or single gang electrical "J" box.

The Elk Plug-in Power Supply (14VDC, 2.6A) has positive and negative screw terminal connections to deliver 2.6A/14VDC power to surveillance cameras, access control, alarm devices, and other security devices. The Power Supply has built-in overload reset to protect devices and provide reliable power. It comes with a mounting bracket for secure installation near your powered device.

The ELK-SWB14P 14" Universal Plastic Enclosure will not interfere with RF signals from Wi-Fi transmitters, wireless receivers, or Z-Wave components. Its design includes slot knockouts on the left and right side for various sized conduits (1/2", 3/4", and 1-1/4"), which allow for integration of numerous components from a wide range of manufacturers; plus, it also has a knockout for a standard AC power J box.
