Fire sprinkler systems are effective fire protection systems that do not need any supervision. Fire can break at any time of the day. Sprinkler systems are one of the most reliable firefighting systems that can control or even extinguish a fire. This is the reason why fire sprinkler systems are known as one of the most reliable fire suppression systems, which protect occupants and property from fire. Sprinkler head (depending on temperature rating) will trip (sprinkler head bulb breaks) when the temperature reaches its temperature rating and allow pressurized water to flow.

Types of Sprinkler Systems

Wet Pipe Sprinkler System

A wet-pipe sprinkler system is a fire sprinkler system contains pressurized water within the piping. When a sprinkler head gets activated by heat, the system will discharge the pressurized water from the activated sprinkler head. If the fire spreads out to other areas of the building and triggers more sprinkler heads, the water will discharge from those sprinkler heads as well.

Dry Pipe Sprinkler System

A dry pipe sprinkler system is a sprinkler system contains pressurized air. When the temperature reaches the sprinkler head™s rated temperature, the head will allow compressed air to release. This will allow dry sprinkler valve trigger allowing pressurized water to flow into the sprinkler pipes and expel from the triggered head. The dry system is ideal for environments susceptible to freezing temperature; however, it needs to be winterized before winter. Please click here for more information regarding the winterization of dry sprinkler systems.


The pipes are either charged with compressed air or water. The pre-action sprinkler system requires two different heads (zones) to be triggered in order to start water flow. If only one of them triggers, bells will go off; however, the sprinkler system will not be activated. If another head gets triggered, the solenoid will be operated at the sprinkler valve. This action will activate the system by allowing water flow in the lines. Pre-action systems are used to mitigate potential water damage by a possible physical or accidental damage to the sprinkler head. The pre-action system is used in buildings where accidental activation can cause significant damage to items. Places like libraries, museums, and data centers are excellent examples of buildings that pre-action could be used.

Deluge System

The sprinkler pipes are not charged with water and the system has open sprinkler heads in the deluge system. A fire alarm system detects the alarm and triggers the sprinkler system to discharge water from all sprinklers heads. Deluge system is appropriate for places where highly combustible materials are present. Power plants, chemical warehouses, aircraft hangars, etc.

Fire Sprinkler System Inspections in Vancouver
Daily/Weekly Inspection
  • Enclosure during cold weather.
  • Pressure gauges. If air pressure fluctuates and the compressor keeps running frequently, a sprinkler technician must check the system to determine the reason for air leakage.
  • Sprinkler room temperature, ensuring that it is higher than 4 Celsius. Some systems, especially newer buildings, have supervisory, which results in fire alarm trouble if the room temperature gets close to 4 Celsius.

Otis Fire Protection technicians will train your staff in performing daily and weekly sprinkler inspections. Contact us now to book for daily/weekly fire sprinkler inspection training.
