different types of fire alarm detectors?




filibini_b


what are the different types of detectors used in fire alarm system? can they be connected all in one zone or panel or they need a separate control panel for each type of detectors?


Answer
* Manual pull stations/manual call points - Devices to allow people to manually activate the fire alarm. Usually located near exits. Also called "manual pull boxes". Other countries have different devices as standard, for example the UK uses 'break-glass callpoints', when people break a small pane of glass to activate the alarm.
* Smoke detectors - Spot type: Photoelectric and Ionization; Line type: Projected Beam Smoke Detector; Air-Sampling type: Cloud Chamber
* Water Flow Switches - Detect when water is flowing through the fire sprinkler system
* Rate-of-Rise and Thermostat (heat) Detectors - Detect heat changes
* Valve Supervisory Switch - Indicates that a fire sprinkler system valve that is required to be open, is now closed (off-normal).
* Carbon Monoxide Detectors - Detects poisonous carbon monoxide gas and usually only connected to household fire alarm systems. Very rarely seen in commercial systems.

They can all be connected to the same panel, however they would normally be reported as different areas/zones at the panel

Whenever I put my heating on, i seem to get REALLY bad headaches, feel sick, drowsy, like i'm getting flu symptoms. Whenever it's not on i feel fine, my heating is done via gas. Could it be something serious?? Please help.
Also to add i've had my flu jab and have been having it for the last 5 years and never seemed to get flu so not sure if it could be flu, now i'm getting really bad stomach cramps :(



Answer
It could be carbon monoxide poisoning. Leave your gas off and go to the hardware store tomorrow get a carbon monoxide detector they're really cheap it's a thing u stick on the boiler and it changes colour if its leaking gas. It's just a little sticker thing this is the uk site for them but I'm
Pretty sure they sell them in the states etc http://www.arctic-products.co.uk/carbonmonoxidedetectors.asp
