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.

Both the 755PSMA2 and 755RLPSMA2 smoke alarms have a ‘Global / Local’ switch located on them (see the diagram below). This switch is only used for operation with the 755RB
relay mounting base.
• When the ‘Global / Local’ switch is set to ‘Local’, only activation of the physically connected alarm will cause the relay to operate.
• When the ‘Global / Local’ switch is set to ‘Global’, activation of any smoke alarm that is interconnected with the base causes the relay to operate.
• The default setting is ‘Global’.
