                Is the PDL SD100 Smoke alarm base interchangeable with the 755PSMA4 smoke alarm?

                Yes, the the 755PSMA4 will fit on the PDL SD100, 755PSMA, 755PSMA2 bases.

                For further information please visit

                Will the 755 base fit the new 755PSMA2 smoke alarm?

                No, the only bases that is compatible with each other is the 755PSMA, 755PSMA2, 755SMA, SD100

                Can the 755PSMA4 be interconnected with the 755PSMA2?

                Yes, the 755PSMA4 will be able to be interconnected with the 755PSMA2.

                Some of the key features are:
                • Modern design with easy to use test/hush button
                • Certified and ActivFire listed to AS3786:2014
                • Easy installation and maintenance

                What are the best SD100 and SD200 smoke alarm replacements?

                The photoelectric Clipsal 755PSMA4 is the replacement for both, even though the SD100 was ionisation type as we no longer supply that type. There is also available a 755RLPSMA4 with a rechargeable lithium backup battery. All current smoke alarm models are compatible and inerconnectable with previous versions. Also available are the 755RFB mounting base with wireless interconnect, the 755RB mounting base with integrated relay, and the 755PFM flush mount.

                Does the new Clipsal 755PSMA2 fit onto the old 755PSMA mounting base?

                Yes - It is backwards compatible with 755PSMA and 755SMA mounting bases

                Are the bases same for 755SMA and 755PSMA?

                Yes, the bases will be the same.


                What is the replacement for the PDL SD100 smoke alarm?

                The PDLSD100 is an ionisation type smoke alarm which we no longer offer. The Clipsal 755PSMA4 is a photoelectric version that is compatible with other Clipsal and PDL interconnected smoke alarms. This is also the upgrade of the Clipsal 755PSMA2.

                Is there much of a difference between the 755PSMA and the 755PSMA2 smoke alarms?

                They are incompareable the internals are completely re-erngineered. the moulding are relatively the same so you are able to interchange them.

                Can multiple 755PSMA4 smoke detectors in a single wired circuit be controlled via a single relay base 755RFB2?

                Multiple smoke detectors cannot be controlled via one relay base, multiple relay bases are required, one for each 755PSMA4 detector. 755RFB2 relay bases can be connected together in a single control circuit for control from one location.
