Powers 460 Series AquaSentry 2 Temperature Alarm System - Manual

The Series LF460 Aqua Sentry 2 Alarm System monitors for
high or low temperature conditions. The system utilizes an
accurate solid state temperature sensor and microprocessor
based digital circuitry to sense and report abnormal tempera-
ture conditions. Standard sensing range is –40°F to 199°F or
–40°C to 93°C (switchable). The alarm panel can be mounted
remotely and provides both audible and visual indication of
alarm condition. With the addition of a solenoid, the alarm can
function as an emergency shutdown system.
A unique latching circuit is used so that the alarm holds
despite a return to normal condition. This feature indicates that
a dangerous condition did exist. The alarm can be silenced
at any time by pressing the reset key. After the temperature
returns to normal, the system can be reset by pressing the
reset key twice. The system cannot be reset while the tem-
perature is outside the setpoints. The alarm module can be
panel mounted, or installed in a standard 4 x 4 electrical wall
box (supplied).
Use of the Series LF460 Aqua Sentry II Alarm System, along
with a electrically actuated valve, helps assure requirements
are met to maintain delivery temperature below (or above) a
certain temperature. (Typical of domestic water systems in
health care and nursing facilities).
