                        hide show

                        Will 755RFB relay base work with 755PSMA?

                        Unfortunately not, 755RFB is not suitable for use with 755PSMA. It is suitable for use with 755PSMA2 and 755PSMA4. 

                        For further information, please visit https://www.clipsal.com/Trade/Products/ProductDetail?catno=755RFB


                        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

                        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.

                        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.


                        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

                        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.

                        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.

                        Can the new smoke alarms fit onto the 755SMA, 755PSMA, SD100 or SD200 mounting base?

                        Yes, the new Gen 2 smoke alarms are 100% backwards compatible. They can clip straight onto the existing mounting bases. The new smoke alarms are also compatible with wired interconnection of all alarms mentioned above as well as the existing 756 isolated relay module. 

                        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.

                        Is the 755PSMA2 be interconnectible with the 755PFM?

                        Yes, they are interconnectible with each other

                        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.
