Carbon monoxide (CO) is a colorless, odorless and tasteless gas that in sufficient concentrations, can threaten life. Due to recent deaths attributed to CO, the codes now have requirements to install CO detectors or alarms in both commercial and residential occupancies that have attached garages or when fossil-fuel burning appliances are in use in an enclosed area.

Let’s refresh our memory on the methods for choosing the correct codes and standards for an installation. With so many, it can be sometimes difficult to determine which requirements we must meet. In many states, there are conflicting codes. So where do you start? READ MORE

The 2009 Life Safety Code underwent significant changes from past versions, especially in Section 9.6 and the requirements regarding voice messages. The International Building Code (IBC) and NFPA 101, the Life Safety Code (LSC), differ in how they handle the delivery of emergency messages. READ MORE

There’s more than just smoke alarms to consider when installing fire protection in houses and apartments. In addition to deciding whether to use ionization or photoelectric smoke alarms, you must determine if you need to install carbon monoxide (CO) alarms or a fire sprinkler system. You also need to consider placement of any CO or smoke alarms. The rules are changing! READ MORE

My last column detailed duct smoke detectors and some of the conflicting requirements we experience. I discussed the basic location requirements for duct detectors—on either the supply or return air side of the air handler unit—depending on whether the International Mechanical Code or NFPA 90A is used.

Everyone who installs or tests fire alarm systems has a few complaints about duct detectors, which are usually located where the accessibility is limited, making them also hard to test. These detectors provide one of the two most commonly controversial issues with fire alarm system installations (the other is smoke detectors in elevator hoistways). There are two conflicting sets of requirements. READ MORE
