How does addressable smoke detector work




















But in terms of buying price, a conventional system is cheaper, and will meet the functional needs of small premises where a sophisticated system is not necessary.

Fire safety on commercial premises is a serious business. As an employer, landlord, building owner, facilities manager, or anyone else in charge of the building, it is your job to prevent fires. Most fatal fires are started by discarded cigarettes, matches and lighters according to Fire Facts , the London Fire Brigade's comprehensive annual review of fire data. Five housing schemes across South Yorkshire will be fitted with sprinklers, thanks to Fire Authority funding.

Wiring differences Addressable alarm systems connect devices using a loop. Which is the cheaper option for you? Which is more reliable? Overall Functionally, the addressable fire alarm unit is superior, which can help prevent costly activities and save time when detecting a fire.

False alarms are always an important consideration when choosing a fire alarm system. False alarms are expensive for fire departments in terms of fuel costs, wear and tear on firefighting equipment, wasted time, and the risk of collision and injury when traveling to the scene.

Not surprisingly, many jurisdictions now impose fines for false alarms, which can add up quickly for a small business. False alarms are far more common with conventional systems because the accumulation of dust and other contaminants on the sensors can send false signals to the control panel. These can be difficult to avoid with conventional systems because there is no way to know if the alarm is false until first responders have arrived and determined, after physically seeking out the detector that triggered the alarm that contamination was the culprit.

In contrast, addressable devices can send a variety of information to the control panel, including trouble signals and maintenance alerts. With addressable systems, the alarm panel monitors the sensitivity level of the smoke detectors to prevent the occurrence of false alarms. The sensitivity of the sensors in addressable devices can also be adjusted.

Without a doubt, addressable systems provide a greater level of fire safety because they allow firefighters to respond more quickly and effectively by pinpointing the exact location of a fire in a building.

There are a couple of other ways that addressable systems can improve fire safety. One is that unlike conventional systems which are limited to the notification of an alarm, addressable systems can combine notification, trouble, and supervisory signals with voice messages to provide instructions or evacuation directions to occupants in the event of a fire.

The fact that addressable systems have fewer false alarms than conventional systems can also help to ensure people take every alarm seriously. When nuisance alarms become common, people begin to ignore them, which can have deadly consequences in the event of a real fire. An addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With an addressable system, both ends of the wire connect to the control panel.

Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop. Addressable systems provide a great deal of flexibility in comparison to conventional systems. While the number of devices either system can accommodate is determinant on the manufacturer of the alarm panels, every type of device added to a conventional system requires a new circuit.

Because they require less wire, an addressable alarm control panel can accommodate far more devices than a conventional system. They can have anywhere from one to 30 loops, commonly referred to as a signaling line circuit SLC , each of which can monitor and control several hundred devices. The equipment required for conventional systems usually comes with a much lower price tag than addressable systems, which is why conventional systems are still a popular choice for small businesses.

However, it is wise to look beyond the initial costs. Even for small buildings, the lower initial costs to purchase the equipment needed for a conventional system are often offset by higher installation costs.

Remember that conventional systems require a single circuit for each zone, one which can lead to much more complex wiring than an addressable system in which all the devices are wired into a single loop. Everything is up and running and I could not be more pleased.

From the first contact through the end of the project Christian kept me informed, answered all of my questions, and guided me in having the correct system installed They were indeed professional, polite, kept their work area tidy and worked around all of the functions we had going on at the church.

I am especially grateful for these men being on our job as they are the face of your company and they represented you well. There was no doubt in my mind that they knew what they were doing. You have no idea how comforting that is. Please extend my gratitude and appreciation for the job they did. I knew we made the right decision! Your install team was amazing! They were extremely efficient and we hardly knew they were there.

Great guys who took the time to show us how to use the system and answered all our questions. Big thanks to you and your team! Anthony came out and explained the SMG capabilities, John updated the system and Dave has been by several times to troubleshoot and solve problems. The three are real professionals and know what they are doing. The administrative staff on the phone are always very helpful and professional. Please thank them for their service.

These guys gave me the best quote for an affordable system!
