The 2L version outdoor tank alarm from Sump Alarm is a weatherproof high tank alarm designed for simple and fast installation with no on-site wiring. Position the float switch, mount the head unit and plug into an outlet. Versions are available for high- and low-level detection, and custom units are available. It has a 1-inch LED red pilot light visible from a distance with an integrated 90 dBA alarm and an always-on white light pump power indicator. It is available with mercury-free float cords in 10-, 16-, 33- and 100-foot lengths, which allow it to be positioned near a secondary power source in a highly visible area for line-of-sight installations. 314/787-8059; www.sumpalarm.com.
