Fire-Lite Alarms recently introduced the new and innovative SWIFT Wireless solution. Wireless technology can help you overcome installation challenges, which makes SWIFT ideal solution for your applications. There is great interest in SWIFT Wireless and we would like to help you learn more by providing the top 10 questions and answers about the products.
1. What is a Class-A Mesh Network? Why is that important with this system?
Class-A is a communications classification where a single fault does not obstruct the system operation. In our case, the mesh network implements redundant paths for all communications, so a single instance when communication is disrupted will not impede the products performance. In wired circuits, this means that a single open circuit or a single short circuit on the communication lines will not prevent the circuit from functioning (typically because there is an alternate/return path). In wireless communications there are no open or short circuit conditions, but there are times when a communication may be blocked (interference or physical blockage). SWIFT implements two communication paths, so even if one is blocked, the message still gets through.
2. What panels are supported? Any plans for the 9050?
The MS-9200UDLS and the MS-9600(UD)LS are supported in LiteSpeed™ mode. There are currently no plans for the MS-9050UD.
3. What do you mean by overlapping? Examples of overlapping?
Overlap occurs when a mesh network is in radio range of another mesh network, creating the opportunity for a transmission in a mesh to interfere with the communication of another mesh. This could be with a system installed on the 1st floor of a multi-story building overlapping with a second network installed on the 2nd floor of a multi-story building. SWIFT Wireless supports a scheme where 4 mesh networks can co-existence in the same RF environment (overlapping) without interfering with each other – This is the limit. If there is a 5th mesh network added to the overlap condition then a system trouble will be indicated for each network that is compromised by the condition.
4. What information can you pull from the wireless detectors?
In panel read status you will have all the capabilities you would get with your wired device (snapshot of chamber values, database settings). With SWIFT Tools, you can retrieve statistics which will have the battery voltages, communication links and signal strength, noise floor measurements, etc. You can also retrieve wireless history from the gateway.
5. What does the SWIFT tool help with?
The tool provides visibility to the radio communication. It has three main functions.
– Extract and analyze site survey data; providing recommendations.
– Installation (assigning profiles, removing profiles, starting/stopping mesh formation, etc.)
– Diagnostics (viewing mesh infrastructure, statistics, history, signal strengths, battery information)
6. Will there be more information on the SWIFT tool available? Online training?
There are a series of short videos on YouTube to demonstrate the capabilities of not only the SWIFT tool, but the SWIFT products in general.
7. How can you get a local AHJ to accept wireless?
Wireless technology is already accepted in many jurisdictions. If you need help with approval in your jurisdiction, please contact a Regional Sales Manager.
8. What is Clip Mode v LiteSpeed™?
Both are communication protocols between the Fire-Lite fire alarm control panels and the addressable devices. LiteSpeed™ is an advanced communication protocol capable of higher speeds enabling additional features. LiteSpeed™ is only supported on the MS-9200UDLS and MS- 9600(UD)LS.
9. What happens at the panel when a device is off or out of service? What shows on the panel? Or ANN-80-W?
The point will be an invalid reply (INVREP) at the FACP. In addition, on the ANN-80-W you may have a latching event to indicate tamper if the device was removed from the base or you may have a latching low battery trouble if the device is completely inoperable.
10. Is there a wireless system guide? Any way to work up a quote without doing a site survey?
A simple site survey is the best way to gauge if the environment is conducive to wireless technology. Without doing a site survey, there is a risk that certain aspects of the building have a negative effect of signal strength.
