script_device_firealarm.lua

--[[Intention of this script is to send SMS, notification and email if fire alarm (“Palohälytin”) goes on.
	If fire alarm device is activated by the security alarm, then fire alarm script doesn’t run.
	The script also loops fire alarm siren if security alarm has been activated as long as defined in "fireAlarmSirenOnTime" variable.
	Own variable fireAlarmActivationType (type: Int) is used to determine if fire alarm device is activated by the security alarm script or not. If yes, then value is 1 else 0 (real fire alarm)
	Own variable securityAlarmActivationTime (type: Int) is used to store time in system seconds when security alarm is activated]]
