Pros and Cons of Rate of Rise and Fixed Heat Detector – In the world of fire detection systems, ROR (Rate of Rise) and Fixed Heat Detectors play an important role in maintaining safety.

Both have advantages and disadvantages that need to be understood in order to be applied according to the specific needs of a location.

In this article, we will briefly discuss the pros and cons of rate of rise and fixed heat detector, so you can make the right decision for optimal protection.

Pros and Cons Rate of Rise Heat Detector

1. Pros

Faster Response: One of the most striking traits of a ROR heat detector is its faster response. Because of its unique working principle, ROR detectors react to rapid temperature rises, making them effective in detecting fires at an early stage, especially those that develop very quickly.
High Sensitivity: Rate of rise fire detector is a type of heat detector that is suitable for spaces that contain a lot of flammable materials and where fires can develop quickly.
Prevention of Large Fires: With early detection, ROR detectors can prevent fires from becoming larger, thus minimizing damage and potential victims.

2. Cons

False Alarm: High sensitivity indeed can be a huge advantage for ROR. But aside from that, this can also be a disadvantage, as it can trigger a false alarm. Rapidly rising temperatures for reasons other than fire, such as faulty HVAC systems, can trigger false alarms.
Not Really Suitable for Every Condition: In environments with already high or fluctuating temperatures, the ROR Detector may be less effective.
Maintenance and Calibration: ROR Detector requires regular maintenance and calibration conducted by professionals to ensure accuracy and avoid false alarms.

Fixed Heat Detectors

1. Pros

Stability: Fixed heat detectors offer significant advantages in environments that experience temperature fluctuations. Designed to react only when the temperature reaches a certain threshold, these detectors provide the stability needed to prevent false alarms due to insignificant temperature changes.
Not Prone to False Alarm: Because it is fixed temperature based, Fixed Heat Detectors have a lower probability of false alarms in certain environments.
Durability: The heat detecting element that fixed heat detectors have is less affected by dust, smoke, or vapor that may interfere with other types of detectors.

2. Cons

Slower Response: Because they need to reach a certain temperature point, fixed heat detectors may not be as fast as ROR detectors in detecting fires.
Ineffective for Fast Spreading Fires: In the case of fires that spread very quickly, these detectors may not provide a quick enough warning.
Installation Position: The installation of this detector must be very calculated so that the temperature can still be detected precisely.

Choosing between ROR and fixed heat detectors should be based on a thorough risk analysis.

Factors such as the type of building, the activities carried out in it, as well as the items stored should be taken into account. A combination of ROR and Fixed Heat Detectors can also be an effective solution.

ROR Detectors are placed in areas where a fire is quickly expected, while Fixed Heat Detectors are used in areas that have high or fluctuating operational temperatures.

But, other than that, knowing the standard and quality of your fire or heat detectors is also as important.

Choose the heat detector regarding its type that has been certified by the SNI certification, as those smoke detectors are the one that has already been tested for its quality and safety aspects.

The SNI certification itself stands for Standard Nasional Indonesia (Indonesian National Standard), which is a type of product approval that regulates most if not all of the products and services sold or provided in Indonesia.

Not only that this will give you a peace of mind as a customer, this certification can also have a huge beneficial impact on business owners alike.

The presence of the SNI logo on your products or having an SNI certification for your service will give you a boost of trust among the Indonesian market and customers.

Not only that, the SNI certification can also be a marketing tool for your business to further improve the reach into the Indonesian market.

And on top of that, the SNI certification is also (sometimes) mandatory, if you want to distribute your products or provide your services in Indonesia.

With that being said, having an SNI certification is also a testament of your business’ compliance with the Indonesian regulation.
Back to the heat detectors, the SNI certification of this product is clearly stated in SNI ISO 7240-5:2018, and SNI 03-3985-2000.
