Martin Schulte-Frankenfeld, Senior Director of Product Management for Fire Detection at Johnson Controls, explains how aspirating smoke detection can help protect mission critical facilities
In mission critical environments, specifying effective fire detection products is more than a precaution — it’s a business and operational imperative.
Whether in hospitals, labs or data centres, having early fire detection warnings is a necessary strategy for protecting the critical assets that keep these operations running.
Without early detection, smouldering fires can go unnoticed until they reach a more critical stage, especially in areas of densely packed equipment.
To catch fires in the early stage, before they cause damage, fire protection professionals are turning towards innovative aspirating smoke detection (ASD) technology that provides advanced warning — and valuable time to react.
While the technology has been around since the 1980s, recent innovations enable ASD to integrate directly with a facility’s fire alarm system, giving operators the power to access highly precise fire detection readings and early warnings of potential fire events, even on their mobile devices.
By understanding this technology, fire protection professionals can help data centres, labs and other mission critical facilities take a more informed, proactive approach to fire detection.
How ASD can help detect danger before it escalates
Initially developed in the 1980s, ASD systems have a long track record of protecting sensitive assets.
The technology can detect early signs of fires before they can cause damage.
A network of small, perforated pipes installed throughout a facility continuously draws in air samples, particularly near potentially high-risk areas that are prone to overheating and smouldering, such as data centre server rooms.
An aspirator (air pump) in the ASD system pulls air through the sampling pipes and delivers it to the detection unit.
With advanced LED- or laser-based technology, the unit detects smoke particles at concentrations much lower than standard detection systems, often before they’re visible to the naked eye.
If the system detects that the concentration of smouldering particles exceeds the set threshold, it issues an early warning alarm to alert building operators.
This allows teams to assess the situation and, if needed, initiate fire safety protocols.
Why ASD works for complex, high-risk facilities
ASD systems are designed to offer several distinct advantages, including:
False alarm reduction
ASD systems employ highly sensitive smoke detection to distinguish between harmless dust particles and actual smoke, reducing the risk of false alarms and increasing peace of mind.
Efficient fire detection
An ASD system can cover larger areas with a single detection unit, making it cost-efficient for protecting expansive or complex facilities.
Effectiveness in high-airflow environments
Some mission critical environments like data centre server rooms and labs can have continuously circulating air.
ASD systems seamlessly collect samples from predetermined locations all around a room or facility, so moving air does not impact operations.
Customisable risk management
ASD systems give building teams flexibility to program sensitivity levels that align with the needs of specific zones.
For example, setting lower sensitivity in non-critical areas can reduce the risk of false alarms.
Likewise, elevated sensitivity levels near high-risk areas can help ensure more rapid detection and response to potential fire events.
Integrating ASD for a layered approach to fire detection
Some ASD systems operate independently of fire alarm systems.
With a standalone approach, facility personnel must be in the same vicinity as the ASD panel to see or hear an alarm.
As a result, personnel may not be immediately aware of the alarm — losing precious reaction time that could be spent stopping an event before an actual fire occurs.
Fire protection professionals can help facility teams enhance ASD system alarm communication by specifying ASD technology that is integrated directly with their fire alarm system.
System integration lets teams monitor fire detection and alarm activity together from a single dashboard.
To add an extra layer of early warning, facility and fire protection teams can also install a remote activity monitoring device that provides mobile notifications and cloud-based dashboard access.
With real-time, around-the-clock access to operational information, building personnel can monitor and manage fire detection systems from any location.
This is particularly useful for teams overseeing multiple sites, whether regionally or worldwide.
A fully integrated ASD system can trigger two stages of alarms.
The first alarm is an early warning indicator alerts to an increase in smouldering particles, which is a warning that a fire event could be imminent.
The second alarm is triggered when the system detects smoke and when the situation requires immediate attention.
It activates local alarms or annunciators to quickly notify building occupants.
Multi-level alarms, especially when delivered directly to a mobile device, allow building operators to investigate potential fire events early and to intervene by looking into the source of the issue.
As a result, teams can reduce the risk of serious harm to assets.
24/7 monitoring helps safeguard operations and prevent downtime
A fully integrated ASD system can deliver a strong value for the investment.
Because an ASD system detects smouldering fires early, they can decrease the risk of equipment or data loss, as well as help maintain uptime.
And, while ASD systems are valuable for alerting teams to fire events in their earlier stages, they provide even more value when integrated with a fire alarm system that offers remote activity monitoring and real-time connectivity for 24/7 awareness.
To ensure mission critical facilities are protected around-the-clock by a safe, compatible, integrated detection system, the best approach is to partner with an experienced full-service fire solutions provider with expertise in mission critical facilities.
An expert partner can help conduct a thorough risk assessment to ensure the fire detection solution is customised to the needs of the project and contributes to safe, efficient and profitable operations for years to come.
