Can the 755RL be interconnected with the 755PSMA2?

The replacement would be the 755RLPSMA2. It can be interconnected with the 755RL, however that model smoke detector is quiet old and we would recomend checking the date on the unit as they need to be replaced every 10 years.


Some of the key features are:

  • New look design with easy to use test/hush button
  • Sealed-in rechargeable lithium backup battery
  • Quality optical chamber with stainless steel insect screen
  • Easy installation and maintenance
  • Wired interconnect feature (up to 40 alarms)
  • Optional relay or wireless interconnect bases
  • Backwards compatible with 755PSMA and 755SMA mounting bases
  • Robust digital design
  • 240V
  • Photoelectric
