      The 'Check Failed Input xxx' message on your Pyronix Security System applies to 24-hour tamper, or other Input types that would generate an alarm condition if the system were returned to disarmed mode. It also applies to tamper faults on other Input types. Check for a fault on the Input, or omit it in programming.
