Sangamo Q551.14.13 Round Pattern Astro Zone Time Switch
Sangamo Q551.14.13 Round Pattern Astro Zone Time Switch. Q551 Solar Dial quartz controlled with battery reserve and day omission, as well as a 3 pin base. The 13 Version gives one ON and one OFF operation per day, the 14 version, gives two ON and two OFF operations per day. The ON operation always tracks SUNSET while the OFF operation can be made either to track SUNRISE, or to occur at a fixed time between 8:30pm and 1:00am.
The Q551 comes in 4 separate ‘Zones’ relating to your latitude, see reverse for map. The Solar Time Switches are ideal for applications which require control linked to sunset and sunrise times. Popular applications for solar time switches include street, stairwell and security lighting.
Once set, the switches track SUNSET and SUNRISE throughout the year, without the need to sense light levels. This avoids the installation and maintenance problems associated with photo sensing devices and means they can be left to operate unattended for years.
