Smart-GUARD
Electronic Thermostat
Details
The Smart-GUARD is an electronic temperature controller for use in freeze protection applications, predominantly in the fire sprinkler market, and is designed specifically to
meet the requirements of BS EN 12845 as described in the LPC regulations and RC38
recommendations published by the FPA.
The regulations require the duplication of trace heating cables with each being separately
switched and monitored.
It can also be used in higher temperature applications and as a single circuit controller too.
The Smart-GUARD actively monitors the 2 independent circuits continuously 24 hrs / 365
days per year on a duty/standby basis. If a fault is detected in the duty heater it will alarm
alert and auto switch to the standby heater.
The Smart-GUARD incorporates an innovative soft-start feature that eliminates inrush
currents, thus allowing for increased circuit lengths over a standard controller.
The unit is designed to work easily with SOLCO PYROELEC heating cable termination kits.
The Smart-GUARD is provided with 4 x plastic bracket clips that allow the unit to be
mounted on a wall directly or alternatively mounted on a pipe using a bracket supplied
by SOLCO PYROELEC.
The Smart-GUARD is ideal to be used in trace heating systems where redundancy
protection is required.
