Safety First provides service to all types of sprinkler systems including wet, dry, pre-action, deluge and fire pumps. We service and maintain all auxiliary equipment such as backflow preventers, fire hydrants, standpipe systems. The 4 most common types of automatic fire sprinkler systems are:

The pre-action system is good for use in sensitive areas such as data centres. This system will only release water into the protected area when it detects smoke/heat physically & electrically. This prevents water damage from an accidental discharge.
Dry pipe sprinklers are similar to pre-action systems as they use pressurized air in the pipe, which exits before water enters. This causes a minute delay in water discharge but is ideal for areas with low temperatures so the pipes do not freeze.
Wet pipe fire sprinklers constantly have water in them. This allows for a quick reaction to a fire and is the most common type of sprinklers installed.
These types of fire sprinkler systems also need a smoke or heat detector like the pre-action system. A deluge system has open heads that can be used when a hazard is present. This type of sprinkler is most commonly used to protect areas where a quick flash out is a possibility.
Safety First will inspect, test and confirm operation of the complete sprinkler system.
- Test all riser and field devices including tamper switches, low pressure switches, pressure type water flow switches and vane type water flow switches
- Complete water flow system activation by opening the inspectors test valve “ITV” on each system.
- Complete a main drain flow test to confirm the water supply to the building and flush the lines.
- Check the operation of the water motor gong, 110 volt electric bell and the excess pressure pump and accessories.
- Complete a visual inspection of the entire building to confirm coverage and installation.
- Complete an inspection report detailing all equipment, devices and the result of the inspection and testing.
- Complete a report on all deficiencies, remarks and recommendations for the system tested.5
