Wireless Smoke Alarm

Good quality, easy to install and most importantly, very competitive price.
I will always consider buying a product from PSL.

10 Year Photoelectric Wireless Smoke Alarm 2020

Exceeded my expectations. Thank you

Good for another 10 years

My existing alarms were starting to require new batteries and had probably reached the end of their recommended life.
Decided to take the plunge and replace all three with a set of 2020 alarms.
Prompt delivery and easy to install and set up.
Very happy with the outcome.
