The Versa’larm I/O from Alderon Industries is a versatile option for indoor and outdoor utility monitoring. This alarm can be used for a wide variety of applications, including septic tanks, sump pits, holding tanks, pump chambers and water tanks. Various types of sensors can be connected for liquid level monitoring. The smoked lens on the enclosure has green LEDs to indicate power is applied, and during an alarm condition, the buzzer will sound and LEDs will flash. Pressing the test/silence button will silence the alarm while alarm LEDs stop flashing. After the alarm is cleared, the system automatically resets for the next alarm cycle. A set of auxiliary contacts rated for 24-volt DC at 0.5 amps maximum allows the alarm to interface with an external device. It is available in 120- or 230-volt AC models. 218-483-3034; www.alderonind.com.
