Do all smoke alarms in a building have to be wired together?
Wutzyerproblem
I would think so because when one goes off everyone else should know there is a fire.
It depends upon local codes and how the building is being used. For example, many state fire codes allow individually placed, battery-operated smoke alarms that need not be wired to anything, let alone connected together, for one and two-family dwellings.

Why do hard wired smoke detector activate alarm?
A smoke detector is designed to activate an alarm if smoke is detected. It does not matter if the unit is hard wired or battery operated. This is its job. In a hard wired system you can interconnect the alarms if a three wire is used between units. The black and white wires are used to power the unit and the third red wire can be inter connected to the alarms in each one of the other detectors in the same system. Hence if one smoke detector alarm trips, the horn alarms in all of the other detectors will go in to an alarm state. This is a very good safety factor and units should be wired this way. For example if a detector trips in the basement at night and there are closed doors between floors you might not hear the alarm in your upstairs bedroom. If all of the alarms sound upstairs and down no matter which unit tripped, you are bound to hear them, no matter what part of the house you are in.
Advantages and disadvantages of an ionization smoke detectors?
Cheap and effective when maintained properly. Smoke detectors will run out of battery over time as they are not wired in to the houses electrical system. Statistics show that far fewer people die in house fires when smoke alarms are present. When the smoke alarms are placed to close to bathrooms steam may interfere with the detector, triggering false alarms. Ionization detectors seem to respond better with high flames which could be a problem under certain circumstances.

Does an electric smoke alarm have a battery?
It depends on your city's fire codes, most likely yes. "Wired" alarms could either mean "wired to AC power" or "wired to an alarm panel" or both. Start by calling your local fire alarm installer or electrician. Assuming that the detectors are wired to a central hub in the house/building (fire alarm control panel), the panel would normally have a battery back-up installed. For individual units wired to AC, having a battery back up would be safer, no matter what the laws. Some units will automatically remind you when the battery is low, even though the unit is on AC power, since the smoke alarm must continue to function if power is off for some reason.

Hard wired smoke detector versus battery operated smoke detector?
Hard wired detectors are generally better. Some have back up power sources should the city power go out. It depends on how much you want to spend. Hard wired detectors are more expensive to install and are generally built better.
How do you stop hard wired smoke alarms from beeping after an electric outage?
Beeping could be caused by several things: an electronic error, a low battery, an expired sensor, nuisance smoke, or an actual fire. NEVER ignore a beeping smoke alarm, or simply remove the batteries without installing new ones. Hundreds of people are killed each year because of disabled smoke alarms. If there is an intermittent beep (e.g., every thirty seconds or minute), it may indicate a low battery or that the sensor is expired. If replacing the batteries does not make it stop, consider replacing the entire unit. If nuisance smoke (or steam) sets off the smoke alarm (e.g., near a kitchen or bathroom), it should be removed and put into a different location, or replaced with a different type of sensor. False alarms have a tendency to cause people to ignore them, which can be deadly. If there is an actual fire, the way to stop the beeping is to put the fire out (if you can do so safely) and then "air out" the room until the smoke dissipates. You should consider replacing a smoke detector if it has been involved in an actual fire, as it may be permanently contaminated and no longer as sensitive as necessary.
