> Inspection General Format
First notify appropriate authority/alarm company prior to testing of alarms. (possibly fire dept. or alarm company if building has central station alarm service).

All Sprinkler System:
1. Inspect sprinklers visible from floor level (not required of sprinklers in concealed spaces) for corrosion, paint, damage, and proper installation. Check for obstructions to sprinklers. Note any problems on report. Test sprinklers on old systems with standard sprinklers after 50 years. Test systems with quick response sprinklers after 20 years.
2. Inspect pipe and fittings from floor level - to be in good condition, not subject to external loads, and not exposed to freezing conditions
3. Hangers inspected from floor level - to ensure they are not damaged or loose.
4. Pressure Gages - Inspect monthly (owner) and annually - our inspection for damage. Gauges must be replaced or tested every 5 years.
5. Water Flow Alarm Devices - Must be free of damage and debris. Test alarms to be sure they operate - wet system via inspector's test; dry system - see dry system detailed inspection routine.
6. Check all system control valves for normal position, damage, or leakage. Note if valves are sealed, locked, provided with tamper switch. Sign in place.
7. Check Fire Department connection - free of damage, debris - easy access for Fire Department couplings, caps are in place and in good condition. Clapper operates correctly. Check valve does not leak. Ball drip in place and operates correctly. Sign in place.
8. Main drain test performed - compare results to previous tests to determine if there has been any change in water supply.

Check riser for:
1. Hydraulic placard
2. Appropriate signs
3. Correct number of spare sprinklers and wrenches

Check building for changes:
1. Added / removed ceilings, walls, mezzanines-change in occupancy

Anti-freeze solution:
1. Test freezing point annually

Dry system inspections - Must be conducted in non-freezing weather
1. Same as wet system for inspection of sprinklers, piping, fittings, hangers, control valves, Fire Department connections, signs, placards, etc. - Building changes

Trip test of dry valve, testing of alarms as follows:
1. Partial trip test of dry pipe valve required annually - means testing of valves operation without completely filling system with water.
--- Must also trip-test quick opening device separately from dry pipe valve
--- Test water flow alarm via by-pass line
--- Test low-air alarms, if provided
--- Reset quick opening device and dry pipe valve after test per manufacturer instructions
2. Full-flow trip test of dry pipe valve required every three years

In addition to visual inspection of piping, hangers, etc., dry systems require every five years visual inspection of interior of piping to check for corrosion. If corrosion in severe, recommend flushing of entire system to owner.
