1. Complete Visual Inspection of Each Unit: 1.1 Pole condition and level. a. Observe pole for any shifting or leaning (Pole should be perpendicular to the ground with no obvious bends). b. Re-seal any holes in the pole to ensure water cannot enter the pole. c. Ensure any bolts, nuts, and other mounting hardware used to secure the pole are free of corrosion and are tight. 1.2 Pier condition. a. Check for major cracks in concrete, earth shifts, etc. 1.3 Grounding of cabinets, antennas a/c transformers, and electrical boxes. a. Ensure ground rods are buried and properly connected. b. Electrical conduits, antenna coax, and antennas. 2. Mechanical Maintenance and Inspection: 2.1 Inspection and repair of siren head wire connections, gears, gearboxes, motor brushes, collector rings, slip clutch, belt condition replacement if needed, and fluid levels. The siren head itself can be inspected once per year instead of twice unless needed. 2.2 Inspection of all internal relays, control relays current and rotate sensors, cabinet. 2.3 Visual inspection of all wiring. a. Record readings on the time meters, if applicable. b. Run siren on “Silent Test” and check motor amperage for sirens utilizing single or threephase power. c. Verify proper amperage, voltage, and other electrical measurements for DC- powered sirens. d. Use siren activation via the control board for testing.
