Product Overview

The FireAngel SW1-R optical smoke alarm is mains powered with a replaceable 9V back-up battery and large, central test and silence button. Two LED status indicators are positioned prominently on the alarm, one clearly showing whether or not mains power is active and the other will light up to indicate a fault or alarm when necessary. Up to 12 W1-R and W1-PF series alarms can be interlinked together via a dedicated cable, including the CW1-PF-T mains powered carbon monoxide alarm, to provide full coverage and reliable warning of possible danger throughout the premises. To ensure that there is a back-up in case of a mains power failure, these alarms also feature a 'safety clip' which prevents them from being fitted to the base plate without a battery.

  • Power: 230V mains powered with backup battery
  • Backup Battery: 9V alkaline battery (included)
  • Warranty: 5 year manufacturer's warranty
  • Large, central test and silence button
  • Up to 12 W1 series alarms can be hard-wire interlinked within a single system, including:
  • Optical smoke detection technology – less prone to nuisance alarms than traditional ionisation sensors
  • Integrated 'safety clip' feature prevents them from being fitted without a battery
  • Suitable for BS 5839-6: 2019 Grade D2 installations
  • Kitemarked to BS EN 14604: 2005

FAQs (2)
Q. I want to install an interlinked smoke alarm system throughout my home, but what type of smoke alarms do I need in different rooms?

We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.

Q. is there a different alarm sound for optical and heat sensors to tell you the difference in what kind of fire it is?

There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
