One-Go/All-Go Wired Smoke Detectors
A great feature to consider when shopping for smoke detectors is one-go-all-go. When smoke detectors are described as one-go-all-go, it means that all of the interconnected smoke detectors will activate if just one of them activates. This can be an important life-safety measure for ensuring that everyone inside a building is alerted to a fire. The feature can be particularly useful for larger buildings when the sounder from one smoke detector might not be loud enough to ensure that everyone knows about a potential fire. That is why you will want to check if the smoke detectors you are installing support the one-go-all-go feature if it is important to you. Keep in mind that you will typically need to get the same types of smoke detectors if you want to use them for one-go-all-go. Trying to mix smoke detectors from different manufacturers will often make it impossible to set up a one-go-all-go network.
When it comes to hardwired smoke detectors, people typically associate high-voltage smoke detectors with the one-go-all-go feature. It is impossible to directly integrate high-voltage hardwired smoke detectors with a security system. However, you can still indirectly integrate high-voltage smoke detectors with a security system by using a listening module. A listening module is installed nearby one of the smoke detectors, usually within six inches of the main unit. It needs to be very close to the smoke detector so that it can hear it activate. Remember, a listening module can only be triggered by hearing the Temporal 3 sound of a smoke detector or the Temporal 4 sound of a carbon monoxide sensor. Make sure that the smoke detector you are using nearby the listening module produces a certified Temporal 3 sound. Otherwise, the listening module will not activate, and your system will not respond to the fire.
The great thing about using a listening module with a network of interconnected one-go-all-go hardwired smoke detectors is that you only need one (1) listening module to take over the entire network. Remember, once one smoke detector on the one-go-all-go activates, all of the other smoke detectors on the network will also activate. So even if the smoke detector nearby the listening module isn't the one that detected the fire, it will still activate as long as at least one other smoke detector on the network had been triggered. With just one listening module, you can take over your entire network of wired one-go-all-go smoke detectors. Remember to test your one-go-all-go smoke detectors to make sure they respond the way that you want them to. It is also possible to achieve a one-go-all-go setup with hardwired smoke detector that integrate directly with a security system, however special equipment is usually required. We recommend contacting us if you are trying to establish a one-go-all-go setup for 2-wire or 4-wire smoke detectors, as setting this up is typically a very advanced task for DIY users.
