                        Can I still purchase the PDL SD100 smoke alarm in NZ?

                        No, this ionisation smoke alarm has been replaced by the Clipsal 755PSMA4 photoelectric smoke alarm.

                        755PSMA4 is there something about these not being approved yet?

                        No, the 755PSMA4's are fully approved.

                        For more information, please refer to the link:

                        What is the current replacement for PDL SD200 Smoke detector?

                        The replacment is a Clipsal 755PSMA4 this is the direct replacement.


                        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.

                        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 Clipsal have a remote frequency smoke alarm?

                        Clipsal has a remote frequency base which, in use with the new 755PSMA4 smoke alarm becomes a remote frequency smoke alarm.

                        Why wont my 755PSMA2 smoke alarms interconnect?

                        To test the interconnect between the smoke alarms you are required to hold the test button for 10-15 seconds. The Smoke alarm you are testing will then pause and you will be able to hear the other alarms start alarming until your finger is released from the test button.
