I am trying to setup a small fire alarm for a remote office which gives sound and light alarm and maybe call or sms the responsible person .
what do you think about the below gear ? note that i will install it myself so very complicated plans are the least welcomed.

1. Fire Control Panel 3270 4 Zone
2. Sealed Lead Acid Rechargeable Battery
2,8ah 12v
3. Optical Detector 17840-01 (20 pcs)
4. Detector Base Low Profile 17800-02 (20pcs)
5. Break Glass 14112-08 Manual
6. Bell 6" 12141-04 24v (red) (4pcs)
7. Strobe/sounder White Red C3-sn-st-wr
Electronic Sounder/Strobe White Body/Red
Lens 100 DBA (IP31)
8. Telephone Dialer Board 6 #, 1 Input, 24
Vdc
9. Fire Resistant Cable 2x1.5mm + Earth +
Screen Lpcb
Certified To BS 6387 CWZ. Not Installed
Interesting. I have no experience in installing advanced fire alarms, and I don't think anyone here has (in Lebgeeks), but I can just tell you what I know on the topic; there is a warehouse where people live in some units and other people work in some other units. It is fitted with a central fire alarm, and the control panel is at the entrance. There was a false alarm (apparently) and the panel was beeping for a whole day, then someone muted it and the false alarm was on for days (probably still on now). So that system was pretty useless. To be fair people live there so if there's a fire we'd know about it.
So anyway I guess the morale of the story is:
- Make sure the system alerts someone who cares (the automatic dialing is good I guess, make sure it is redundant, maybe dial more than one person. Prefereably someone who lives nearby)
- Take in consideration the very real possibility of false alarm. If this is a remote place you don't want a false alarm to alert everyone. Eventually, given enough false alarms everyone will end up ignoring the system.

So anyway it's likely that you already know all that, but I have no technical experience so that's all I can contribute.

HI there.

Can you please provide the area of the office and the number of rooms ? because i have noticed there is quite a few detectors. Also you might want to consider increasing the number of manual call stations.

I would suggest replacing the bells for mini horns. much more pleasant on the eye for an office and they are addressable without needing any relay or supervised output modules.

There is an option out there to buy a Fire Alarm Control Panel with an integrated dialer. But you can also purchase one from EKT for about 35$.

You can also use sounder bases for advanced alarm function which is to alert people inside the fire zone of danger. People aren't always aware of what's happening, unless you're installing sufficient horns.

You should also be careful not to over shoot the Fire alarm control panel you need. You only need 1 loop so don't over pay for this.

One last thing, please don't forget the fire extinguishers.

hello , the office is two stories , about 20-30 rooms .
would the mini horns give enough decibels for sound alarm ? what are exactly the sounder bases ?
would the dialer work with a sim card ? as there is no phones in the office ( only internet central and ip phones between branches )
i have manual fire extinguisher ( CO2 and foam ) with sizes ranging from 5 to 50 kgs distributed around the office .

I want to add that the building has a faux-plafond ( a fake ceiling made of wood ) so i would probably need to add few detectors there as well .

what would you advise me ? my needs is a fire alarm that would give sound and visual alarm in the first place .
I worked with fire fighting systems but was mostly concerned with the mechanical part so i cannot go into technical details when it comes to alarm systems, but i ll try to hel a little:
the cabling to be done in one closed loop
usuallay, inside the rooms you dont put sirens, u focus on strobes, while outside the building is where you fix the bell/horn and again strobes.
mechanical pull switch (break glass) to be applied in accessible places preferebly near main doors
cabling should be done through proper galvanized steel conduits, 3/4" or 1" should do, depends on how many cables to be pulled in them.
finally, once system is installed, you need to do proper continuity test.

if you any particular questions ill try to ask my colleagues for you.

regards
Well, depending on the size of the room you might need more than 1 detector per room. So as long as the area of each room is under 50 m2 one detector would do.

You will want to install a smoke detector in each room. Then you will need smoke detectors in hallways where there is also a risk of Fire.

The mini horn should give you around 90dBA at 3 meters or 100dBa at 1 meter so yes its enough.

Sounder bases are bases for mounting the detectors but they have a little sounder integrated into them so they give an alarm as well. would be useful for sounding an alarm inside the rooms. I don't know what the sound level these offer as it depends on the maker/model.

The dialer I told you about operates through a phone line but I'm guessing there would surely be a Sim card model.

You'll need manual call stations (break glass) near Main doors (stair cases) and in the middle of hallways near the elevator.
alright guys thank you for your help ..let this be our first security thread .. i have some question :

- what exactly is a closed loop ? should all the sensors and sounders be connected to the main alarm station ?
- is fire delaying power cables needed for the installation or can i use any electrical cable ?!

let us write all the equipment needed .
Closed loop is when the cable starts from one device and go through all the other devices and connects bsck to the first device.
I dont know about thr fire alarms youbare working with but the one i worked with is called "notifier". The panel will display which smoke detector detected the fire on the panel so that the fire fighters can know exaclty to which room they need to go. For that to work, you need to do proper labeling for all smoke detectors, and then program the panel for it to display the name of the concerned smoke detector. You will have a drawing or list next to the pabel to specify each smoke detector refers to which room.

what you need:
fire alarm cable
power cable
Smoke detectors
Steel conduits ( to properly guide the cable and protect it from fire or any ither possible damage)
Clamps to fix the conduits to the wall
manual pipe bender
Electrical boxes
manual mechanical pull stations
sirens/ horns/ strobes
fire alarm panel
threaded rods, pipe hangers and steel fishers if you cannot fix the conduits directly to wall or ceiling
living in Lebanon, this is important, ups with long battery life
labeling machine or print labels locally if you can

Hope i havent missed any item.
