Can 755PSMA, 755SMA , 755PSMA2 and 755PSMA4 be interlinked together?

Yes they can all be interlinked together.
Interconnecting smoke alarms is a method of joining a series of alarms so that if any one alarm senses smoke, all the connected alarms will operate (alarm). 
A 9 V signal is applied to the interconnect wire (referenced to neutral) to alarm all the other interconnected alarms.
• All interconnected smoke alarms must be supplied from the same circuit.
• A common Neutral must be used for the Interconnect to operate.
• DO NOT connect the Interconnect wire to Active or Neutral.
• A maximum of 40 Clipsal 755 smoke alarms can be installed on one circuit (wired interconnection only).
• Only Clipsal smoke alarms can be interconnected with each other.
Failure to follow these instructions may result in injury and equipment damage / malfunction.

What is the warranty period for the 755 series smoke alarms?

The 755 series smoke alarms have a 5 year warranty period

Why does my smoke alarm randomly keep going off, and how to stop it?

This is mainly due to something setting it off ie. Dust partials, dust mites, bugs, dirt. To avoid this it is recommended to clean your s/a every month, the best way to do this is by getting a long nose vacuum and vacuum the outside of the alarm trying to get in all the gaps. *NOTE DO NOT OPEN ALARM AND DO THIS AS IT MAY DAMAGE THE ALARM. Spray bug repellent on a cloth and wipe the ceiling around the smoke alarm to act as a future bug deterrent. Test the smoke alarm after cleaning.
