You can use a PNP or an NPN transistor in a fire alarm circuit. Both will work. It all depends on how you want to energize the alarm, and with what polarity of signal.
The terms can sometimes mean the same thing: a self-contained smoke detector with a built-in fire alarm.However, they are technically different and can be obtained in many types.A fire alarm SYSTEM can contain smoke detectors, heat detectors, manual pull stations and other sensors related to fire protection, including switches that say the fire sprinklers or the commercial kitchen fire extinguisher has activated. All of these sensors and switches are wired to a fire alarm control panel that monitors them constantly for electrical trouble or for alarm conditions, relaying the alarm message to bells, sirens, strobe lights and maybe even calling the fire department.Most people say "smoke detector" when they mean "self-contained smoke alarm". The smoke alarm does not usually connect to anything other than maybe another smoke alarm or two, so they all make noise when there is a fire, but someone still has to remember to call the fire department.

You have lost all fire protection in that building if the over all "general alarm" has been disabled. You will need to contact a fire alarm contractor to assist in bringing the system back up, and to meet code requirements. If you are not responsible for making these decisions, then call your local fire station and determine with them the fire marshal responsible for your area and file a complaint.

There are many different kinds of fire doors and not all of them are tied to the alarm system. Some fire doors will only close when there is enough heat to sever a fusible link. However, as a general rule, automatically closing fire doors that are latched open with electrical controls would release the latch and close the relevant fire doors upon triggering of the fire alarm by any initiating device.
