Elk M1 Gold Alarm System TCP Interface
Author: Mike Thompson, GitHub: mike-linus Date: 14/8/2016 Updated: 22/2/2017 - added time delay for multiple word speech
The Elk M1 alarm is a very capable alarm system that provides TCP network access via the optional ethernet interface.
Elk fortunately documented the command set in their RS-232 Interface Specification ref. ELK-M1_RS232_PROTOCOL
Some excellent Interfaces have been built using node.js ref. https://github.com/kevinohara80/elkington and Perl ref. https://sourceforge.net/projects/elkm1control/ but are missing key components and are not designed to work with node-RED or MQTT.
The example flow shows how to monitor alarm messages, issue speech commands and other general commands. A continuous speech routine is also included.
To use, alter the TCP nodes to point to the IP address of your alarm.
Note: The nodes have been configured for use on the internal network using the default non-secure port 2101.

interface.\n\nElk fortunately documented the command set in their RS-232 Interface Specification ref. ELK-M1_RS232_PROTOCOL\n\nSome excellent Interfaces have been built using node.js ref. https://github.com/kevinohara80/elkington and Perl ref. https://sourceforge.net/projects/elkm1control/ but are missing key components and are not designed to work with node-RED or MQTT.\n\nThe example flow shows how to monitor alarm messages, issue speech commands and other general commands. A continuous speech routine is also included.\n\nTo use, alter the TCP nodes to point to the IP address of your alarm. \n\nNote: The nodes have been configured for use on the internal network using the default non-secure port 2101.","x":263,"y":41,"wires":[]},{"id":"a1fc7a9f.d1e978","type":"delay","z":"cddb8bb1.322478","name":"","pauseType":"rate","timeout":"5","timeoutUnits":"seconds","rate":"1","nbRateUnits":"1","rateUnits":"second","randomFirst":"1","randomLast":"5","randomUnits":"seconds","drop":false,"x":316.8332824707031,"y":565.0000305175781,"wires":[["b3f796f8.4c0868"]]},{"id":"fca9574c.0356a8","type":"mqtt-broker","z":"","broker":"192.168.2.40","port":"1883","clientid":"node-red","usetls":false,"verifyservercert":true,"compatmode":true,"keepalive":"15","cleansession":false,"willTopic":"","willQos":"0","willRetain":"false","willPayload":"","birthTopic":"","birthQos":"0","birthRetain":"false","birthPayload":""}]
