The use of a computer system in this instance is overcomplicating things. Fire alarm systems need to be simple, robust and reliable because peoples lives depend on them. A computer system will require custom hardware to interface with the alarm system in order to detect that the alarm has been activated. Upon detection of a fire the system must then connect to some form of mass sms mailing system to send the messages. These messages could take some time to reach the recipients, be sent to people not in the building or not be sent to new arrivals in the building. This requires a significant amount of management to keep numbers up to date. A far simpler solution is to have flashing lights mounted near the sirens so that a visual indication is provided for people with impaired hearing. In some large installations I have seen the fire alarm system disconnects both mains electricity and gas power to the facility then battery backed emergency lighting switches on. This would also give a visual indication to deaf people that the fire alarm has been activated.
some use sign language
I would recommend you to edit your question to be more descriptive, perhaps 'SMS based fire and emergency warning system' would suit your title better. Good luck! 👍
Martin Taylor It just came to me that cellular signal tend to weaken or sometimes even lost totally while one was inside a building (basement is worst place really). I don't know if it's just in my country or everywhere, but this I guess also worth a consideration. A fire or emergency message delivery failure could mean something horrible for those in the building. I think "normal" people should be taught to be more humanist to others in a place where people with different abilities are present. Thanks for stopping by, much appreciated 👍
Stefano Armando Chibia It sounds like you want to implement an Emergency Notification System that is integrated with the fire alarm system. I would research professional companies that specialize in this type of service. I came across a blog from one such company that provides this type of consulting. Here are some relevant articles from their website. https://www.singlewire.com/blog/mass-notification/mobile-alerts-challenges https://www.singlewire.com/emergency-notification-system https://www.singlewire.com/blog/emergency-notification/device-integration https://www.singlewire.com/blog/emergency-notification/mass-notification-ecosystem https://www.singlewire.com/blog/emergency-notification/fire-alarm-integration I hope this helps.
Stefano Armando Chibia Are you a teacher? Wouldn't it be more convenient to create a group in a messaging app to broadcast a message for the recipients? I guess SMS isn't as much used these days due to the economic price compared to internet data.
Good question, that would involve system integration, I'm no expert there. But as I understand it, when a fire detection system works, it rings the sirens and switch open the fire hoses on the ceiling. Isn't the siren good enough to signal everyone to evacuate? I think sound of the sirens is more important than an SMS (just my opinion).
David Carroll Thank you for sparing time on researches. Apart from cost matter, I agree this issue may better off be handled by professionals. This concerns life of many 👍
it has really helped alot. thanks alot
David and Martin
am not a teacher but then how do i connect that with a fire alarm system.
very valid point. but i was just thinking of making it more formal as not all students can hear
I see, well, there is this SMS gateway system I heard about. Perhaps you could try to look it up, and assess whether if it is a feasible option for the fire event early warning system you plan to build. Give it a little more time, I hope someone experienced could drop their opinions on this subject 👍 (Edited)
