International testing of smoke, heat, CO and multi detectors at the heart of global standards. The recall was necessary because an internal contact could have had insulating film, preventing the detector from reporting a heat alarm signal to the control panel. This occurrence underlines strongly the need for proper functional testing — both at installation, commissioning and acceptance and on an annual basis.

Using examples from the national codes of the UK, United States, France, Germany and Canada, it is evident that other countries have similar requirements, but some can be clearer than they are now.

xpsad The product recall underlines why such standards need to be adopted where they do not yet exist, clarified where they are misunderstood apsac upheld and enforced where they loosely followed. But the UK’s code also explains what is not acceptable. A functional check is not something that can be conducted by only checking analogue values, nor is it something that e7 be accomplished with a magnet. Use of a test button or a test magnet does not satisfy the recommendations states the UK’s British Standard 1: Its goal is to check that each detector has the capability of picking up that which it is designed to detect.

As to how the functional checks can be performed, R7 explains that the person performing the work should be equipped with the necessary non destructive tools for the job that are compatible with the detectors and produce the appropriate stimuli to activate the detectors under test smoke, aerosol, heat, IR or UV generators.

In a harmony rarely seen among these five nations, the Germans concur and DIN Avoiding Danger Extending this theme many national standards now refer not only to the need to check the device, but also the need to avoid danger or other damage to — or from — the environment in which t7 detector is installed.

This is encapsulated by the UK’s BS The heat source should not have the potential to ignite a fire, live flame should not be used and special equipment might be necessary in explosive atmospheres,” said the UK’s British Apdad. The French and British are of one mind and France’s R7 states that devices producing live flames, such as lighters, are prohibited.

Xpsad theme of avoiding damage also is explicitly recognized for other detectors.

Fire Safety System (FSS)

Smoke detectors, for example, might react to various stimuli, but setting them off properly with apsaf genuine physical functional check is only part of the art. Avoiding damage to them, for example, is another. Again, this is picked up by the British Standard. It should be ensured that the material used does not cause damage to or affect the subsequent performance of the detector,” apsa the British Standard. An open flame shall not be used for testing the operation of heat detectors,” said the British Standard.

When all these tests should be conducted? The answer is at commissioning and annually, though the annual tests are often split over the course of two or more occasions. Similarly, the British standard states that tests should be conducted at commissioning. At commissioning, the Germans also require that percent of all installed system components be tested and that, in the case of automatic fire detector tests, the alarm be triggered out by simulating the characteristics of the a;sad at the detector.

The checks can be split into two, six-per-month checks. Nonetheless, the checks must not be less frequent than six per month. Six monthly visits by a competent person to every detector is, of course, a wise step for a number of reasons. Not only can a proper functional check on an ongoing basis highlight the inability of a detector to raise an alarm for reasons which may range from component failure, to wiring damage to dust covers, or other barriers to detection.

It also provides an opportunity for an expert to assess building, usage and other changes that may impact the reliability or suitability of the detector relative to its installed environment.

One area relates to the ongoing sensitivity of a detector. This is something that cannot be assessed at all with most conventional detectors without a specialist test device. It also is one where even the faith in analog detectors,assessing as they do only the sensors as opposed to the ability of them to receive stimuli, is flawed. NFPA 72 said that to ensure that each smoke detector or smoke alarm is within its listed and marked sensitivity range, it shall be tested using any of the following methods:.

Detectors or smoke alarms found to have a sensitivity outside the listed and marked sensitivity range shall be cleaned and recalibrated, or be replaced. The Canadian code is in concert with this, as well. Acceptable methods of determining the smoke detector sensitivity are:. Installed control units or transponders designed to test the sensitivity of individual smoke detectors. Finally, the other area looking for clarification is that of multi-sensor detectors.

The confusion has a single clarification for the purpose of field testing — it does not matter whether one defines them as multi-criteria or multi-sensor. Neither does it matter how they are configured or when.

Wherever possible, sometimes limited by the test modes available, each of their separate sensing abilities must be tested in the same real functional manner and at the same times.

NFPA 72 said that to ensure that each smoke detector or smoke alarm is within its listed and marked sensitivity range, it shall be tested using any of the following methods: Manufacturer’s calibrated sensitivity test instrument. Listed control equipment arranged for the purpose.

Other calibrated sensitivity test methods approved by the authority having jurisdiction.

Acceptable methods of determining the smoke detector sensitivity are: Manufacturer’s recommended test instrument, equipment or method.
