The 4 Best Void Fire Detection Solutions

The most appropriate detection systems for inaccessible areas

What is Void Fire Detection?

Void Fire Detection is heat or smoke detection for void spaces such as voids above suspended ceilings, or void spaces underneath raised floors. According to BS5839-1:2017 if these void spaces are greater than 800mm in depth, void detection should be provided. If the void is less than 1500mm in depth, all such detection should be sited in the top 10 per cent or 125mm of void depth, whichever is the greater.

What do applications such as void spaces and lift shafts all have in common?  The answer is inaccessibility.  

Inaccessible areas are often oddly shaped, confined spaces with little or no access possible. This means that access for maintenance may be severely restricted making regular upkeep difficult.

What are the most appropriate detection systems for inaccessible areas?

1. VoidAlert™

Void detection is a fraught issue, especially on new-build projects. From a design perspective, it is difficult to predict the amount of detection required and invariably, providing access for ongoing maintenance is a challenge.

VoidAlert™ heat sensitive sensor-wire is installed through the protected area between the VoidAlert™ Remote Indicator and VoidAlert™ Test Point. The Test Point is typically installed in an accessible location to facilitate ongoing engineer maintenance.

Benefits of VoidAlert™:

  • Remotely tested for minimum disruption eg in ward areas
  • Eliminates need for safe-access routes within void spaces
  • Enables voids to be fully enclosed without need for access hatches
  • Reduces life-cycle maintenance costs

2. Aspirating Smoke Detection

Aspirating Smoke Detection

An Aspirating Smoke Detection (abbreviated to ASD and known as HSSD) system works by drawing air from sampled areas, via a network of pipework, back to a localised aspirating smoke detector. The ASD will then send an alarm signal, via an I/O interface, back to the fire alarm control panel. The panel will then make a decision, based on the designed cause & effects, on how to output the alarm signal.

Aspirating Smoke Detection is a versatile solution that offers:

  • Higher sensitivity and the flexibility of design
  • Very early warning of fire and discrete detection
  • Airflow analysis and ignition point targeting
  • Work alongside existing smoke detection and air conditioning systems
  • Lower installation and maintenance costs

3. Scorpion

Scorpion

Scorpion is an innovative solution for functionally testing any hard-to-access smoke detector, whether that is a point detector or aspirating smoke detection (ASD) system.

It ensures all smoke detectors can be tested – regardless of location.

Benefits:

  • Tests hard-to-access detectors
  • Minimal Disruption - No need for specialist access equipment or personnel
  • Cost-saving & Time saving – less time spent organising and carrying out testing
  • Compliance – ensures all detectors can be tested as required by standards

Scorpion Smoke Detector Testing Systems are ideal for lift shafts, ceiling voids, secure rooms, high atria, plants, warehouses etc.

4. Rapid Bracket® Void Detector Holder

Rapid Bracket® Void Detector Holder

Compatible with most ceiling types and a large variety of detectors, Rapid Bracket® ultra-fast installation time reduces labour costs significantly and eliminates the need for unsightly access hatches, while leaving a modern, aesthetically pleasing finish.

Benefits:

  • Rapid installation
  • Compatible with a variety of detectors up to 128mm in diameter
  • Easy removal and reinstallation during periodic testing and inspection

STEP 1:
STEP 2:
You provide a suitable up to date drawing of your building in either:
  • Hard copy
  • PDF
  • Or preferably AutoCAD (dwg) format
Depending on the availability of installation records and the complexity of the building, we arrange a visit to identify the zone number associated with each Fire Alarm Manual Call Point and Fire Detector (for practicality this may involve two engineers).

STEP 4:
Fire Alarm Zone Chart is created.
Fire Alarm Zone Chart is supplied in A4 or A3 glazed frame for installation adjacent to your Fire Alarm Panel.

False Fire Alarms remain a huge concern within the education sector- interrupting already carefully scheduled, planned and well-prepared lessons or even causing major disruption and distress to exams.  

Clearly, these false alarms cause significant inconvenience and disruption to students, staff, and visitors. They compromise everyone’s safety in the school and present a significant risk to the local community since the Fire Brigade will prioritise the school over other emergency callouts.

Solutions you should consider:

Anti-tamper products

The first and most straightforward way is to use anti-tamper products.

Fixfire® supplies a wide range of solutions designed to protect Fire Alarm Devices from inadvertent damage or deliberate misuse/vandalism.

Products include:

  • Local plastic cover flaps which attach directly to manual call points.
  • The stopper consists of a clear, tamperproof, tough polycarbonate cover, frame and spacer that retrofits over a break glass call point. When lifted to operate the break glass unit, its optional battery powered integral sounder emits a piercing 96dB (at 1m). Immediate attention is drawn to the area and a prankster will either run or be caught!
  • A range of steel web stoppers designed to protect fire detectors and warning devices. They are constructed from heavy-duty galvanised steel rod which is plastic-coated for durability and external use.
  • A range of polycarbonate enclosures are available for the protection of devices such as fire alarm control panels and associated control equipment. The enclosures combine tough rugged construction with stylish design and offer excellent protection with a key lock for authorised access.

We also provide anti-tamper devices for fire extinguishers and associated products.

KeyCall® Call Point

KeyCall® is a patented anti-ligature Fire Alarm and Access Control call point. It is designed to use the same key as the doors, providing simple operation for staff whilst eliminating nuisance activations by service-users.

KeyCall® has been developed by Fixfire® specifically for approved applications where standard versions would be vulnerable to abuse.

It is one of the best solutions for SEN schools and it is also compatible with a wide range of Conventional and Addressable Fire Alarm Systems.

Conduct Fire Safety Training

Most fire safety courses offer a mix of classroom-based learning and practical training experience, educating attendees on how to respond in the event of an emergency.

 In order to fulfil your obligations under current Fire Safety Law, it is essential that you have a documented regime of Fire Safety tests and checks and personnel who are suitably trained to respond correctly in the event of an emergency.

All Fire Safety Training is provided by experienced, time-served and qualified persons from a Fire Safety background.

Video surveillance

Even if the cameras don't identify the culprit, they can identify who was in the area at the time of the false alarm activation. Fixfire® specialises in integration and will bring together your Fire, Access and Security systems providing enhanced functionality.

Fixfire® provides leading-edge integration with ancillary systems and equipment. Our mission is to deliver reliable, well-engineered installations that provide you with peace of mind 24/7.

Place fire detectors in the correct locations

Smoke detectors that are placed too close to kitchens, cooking appliances, locker rooms or bathrooms will most likely be accidentally activated by the smoke or steam emitted by these sources. Detectors might need to be relocated.

Smoke detectors are more sensitive and are installed in any environment where smoke or steam would not normally be present. Heat detectors are installed in areas such as kitchens where smoke detectors would constantly false alarm during routine cooking. Multi-sensors combine smoke and heat in one detector and offer immunity to false alarms in certain applications.

Use the right detector

New detectors have improved technology and can measure a range of conditions to potentially be more effective at detecting a fire condition.

Flush Fire Detectors ensure protection is not compromised in any areas where conventional ‘un-pluggable’ detection could be subject to abuse. It is widely used in SEN Schools.

Maintain your Fire System

Make sure the alarm system is properly and regularly maintained.

Fixfire® is BAFE accredited for the Design, Installation, Maintenance and Servicing of Fire Alarm Systems.

All works are carried out by our employed, uniformed and trained Fire Alarm engineers.
Following each visit, a Certificate of Inspection is issued.
