/*********************************************************************************************\
* This protocol provides support for some Alarm sensors that are part of a Varel/Chubb/Ajax alarm
*
* Author : StuntTeam
* Support : http://sourceforge.net/projects/rflink/
* License : This code is free for use in any open source project when this header is included.
* Usage of any parts of this code in a commercial application is prohibited!
*********************************************************************************************
* Changelog: v1.0 initial release
*********************************************************************************************
* Technical data:
* Devices send 25 pulses, first pulse is part of the start bit. Remaining bits are Manchester encoded, 24 bits
*
* The PCB contains a Holtec HT12E Encoder chip
* The PCB has two switch blocks: SW1 with switches 1-8 (Device code?)
* SW2 with switches 1-4 (House code?)
*
* Sample:
* 20;74;DEBUG;Pulses=26;Pulses(uSec)=425,425,800,875,350,875,350,875,350,875,350,875,350,875,350,875,350,400,800,875,350,400,825,875,350;
