- Fire Hose Reel ("FHR")
A fire hose reel (FHR) is a first-attack fire protection appliance designed to provide an immediately accessible, continuous, and controlled supply of water to extinguish Class A fires involving ordinary combustible materials such as wood, paper, textiles, and plastics.
The primary objective of a Fire Hose Reel is containment; it enables occupants to control or suppress minor outbreaks before they escalate into structural catastrophes, thereby safeguarding evacuation pathways and limiting property damage.
In contrast to a fire hydrant system, which is engineered exclusively for high-volume water supply for fire suppression by trained emergency services personnel, a fire hose reel is designed for safe operation by building occupants during the initial stages of an emergency. Furthermore, unlike portable fire extinguishers that offer a highly restricted discharge duration, a fire hose reel provides an inexhaustible stream of water, bounded only by the capacity of the connected water mains or storage supply.
Fire hose reels serve as a critical component of a building’s active fire protection strategy. They are permanently connected to a pressurised water supply and strategically located throughout commercial, industrial, and large residential structures.
Core Mechanical Components
A compliant fire hose reel assembly consists of several distinct parts engineered to withstand harsh environmental conditions and high operational pressures:
- Reel Drum: A heavy-duty steel spool assembly consisting of two interlocking side plates painted Signal Red to ensure rapid visual identification within a facility. Drums are available in either mild steel or stainless steel for harsh operating environments.
- Semi-Rigid Hose: A specialised, non-kinking, UV-stabilised rubber or PVC hose—typically featuring a 19 mm nominal diameter and a standard length of 36 metres—designed to maintain its circular cross-section even when fully wound.
- Interlock Valve: An isolation valve connected to the water supply that requires the operator to turn on the water before the hose can be fully unwound, preventing accidental deployment or dry operation.
- Twist-Type Nozzle: A durable brass or polymer discharge device fixed to the end of the hose, featuring clearly marked, operator-controlled adjustments for 'OFF', 'JET', and 'SPRAY' configurations.
- Hose Guide Arm: A pivoting mechanical guide or roller assembly that facilitates the smooth, snag-free extraction of the hose in any direction. Wall-Mounting Bracket: A robust structural backing plate designed to securely anchor the weight of the pressurised reel assembly to walls, columns, or freestanding internal cabinets.
Technical and Hydraulic Specifications
To guarantee operational reliability during a fire event, the manufacturing and physical performance of an FHR must comply with rigorous engineering criteria:
- Maximum Working Pressure: The assembly must safely operate under standard system pressures up to 1200 kPa.
- Hydrostatic Test Pressure: Component designs must withstand a factory test pressure of at least 1700 kPa without structural deformation or leaking.
- Minimum Dynamic Performance: The supply pipework must deliver a minimum dynamic pressure of 200 kPa at the nozzle outlet, ensuring an effective flow rate capable of suppressing Class A risks.
Spatial and Installation Criteria
The physical placement of an FHR is governed by strict accessibility mandates to ensure usability by all building occupants, including individuals with limited mobility:
- Mounting Height: The centre hub of the reel drum must be positioned between 1400 mm and 2400 mm above the finished floor level.
- Nozzle Accessibility: The nozzle must rest in a dedicated cradle located no higher than 1200 mm from the floor to enable easy reach.
- Coverage or Reach: Installation locations are calculated based on the 36-metre hose length, ensuring total coverage of the designated floor area without dead zones.
Legislative and Compliance Framework
Fire hose reels within Australia are subject to a strict national compliance framework spanning design, installation, and ongoing preventative maintenance:
- AS/NZS 1221: This standard dictates the manufacturing specifications, component materials, and performance testing criteria for the physical reel equipment itself.
- AS 2441: This standard governs the precise installation methods, systematic location criteria, water supply interconnections, and required spatial clearance zones within buildings.
- AS 1851 (Section 9): Regulates the mandatory routine service intervals, requiring certified technicians to conduct visual and operational checks every six months, dynamic flow testing annually, and hydrostatic pressure testing every five years.
- National Construction Code (NCC): Serves as the overriding statutory framework, defining the exact building classifications, sizes, and floor areas where the installation of fire hose reels is legally mandated.
Facility managers and property owners must ensure these assets remain completely unobstructed within designated clearance zones to allow rapid deployment during a fire crisis.
