In the event your trouble light is on follow your security system instructions to display the trouble conditions. Typical trouble conditions may originate from external sources such as a loss of commercial electrical power or an interruption to a telephone line or internet access. Internal problems may be a depleted standby battery, a depleted battery in a wireless detection device (motion detector, door contact, wireless smoke detector, etc.) or a physical wiring problem. Please consult with our signal receiving centre operators or tech support team to assist in diagnosing the problem.
