Self Diagnostics. Each Building Controller shall continuously perform self diagnostics, communication diagnosis, and diagnosis of all panel components. The Building Controller shall provide both local and remote annunciation of any detected component failures, low battery conditions or repeated failure to establish communication for any system. Power loss. In the event of the loss of power, there shall be an orderly shutdown of all Building Controllers to prevent the loss of database or operating system software. Non-volatile memory shall be incorporated for all critical controller configuration data and battery backup shall be provided to support the clock and all volatile memory for a minimum of 30 days. Environment. Controller hardware shall be suitable for the anticipated ambient conditions. Controllers used outdoors and/or in wet ambient conditions shall be mounted within waterproof enclosures and shall be rated for operation at 0°C to 49°C (32°F to 120°F). Controllers used in conditioned shall be mounted in dust-proof enclosures and shall be rated for operation at 0°C to 49°C (32°F to 120°F). Immunity to power and noise. Controller shall be able to operate at 90% to 110% of nominal voltage rating and shall perform an orderly shutdown below 80% nominal voltage. Operation shall be protected against electrical noise of 5 to 120 Hz and from keyed radios up to 5 W at 1 m (3 ft). Isolation shall be provided at all primary network terminations, as well as all field point terminations to suppress induced voltage transients consistent with: RF-Conducted Immunity (RFCI) per ENV 50141 (IEC 1000-4-6) at 3V. Electro Static Discharge (ESD) Immunity per EN 61000-4-2 (IEC 1000-4-2) at 8 kV air discharge, 4 kV contact. Electrical Fast Transient (EFT) per EN 61000-4-4 (IEC 1000-4-4) at 500V signal, 1 kV power. Output Circuit Transients per UL 864 (2,400V, 10A, 1.2 Joule max). Isolation shall be provided at all Building Controller’s AC input terminals to suppress induced voltage transients consistent with: IEEE Standard 587 1980 UL 864 Supply Line Transients Voltage Sags, and Dropout per EN 61000-4-11 (EN 1000-4-11) Keypad
