A large two-story house without floor or ceiling space presents a huge problem if wanting to retrofit anything electrical, including smoke alarms.
Every smoke alarm needs to be heard throughout the premises, which is often impossible, therefore they must be interconnected. These wireless interconnected units offer the quickest and easiest solution at a most reasonable price.
The ordering process is intuitive and PSL handled dispatch efficiently, a courier tracking number was provided too. Installation was achieved easily using the nylon plasterboard plugs and screws, however, the instruction sheet while adequate could be improved with more detail about the set up protocol to assist those who are not familiar with planning sequential steps. The project involving four units was completed in less than one hour, everything went smoothly and the system tested out correctly.
