Product Overview

™

For use in wet pipe water mist systems System Sensor’s Accuflow Low Flow Rate detectors are a new line of solid state

waterflow detectors designed for use in wet pipe water mist systems where low

Compatible with 2 to 4 inch stainless

steel and brass pipe

flow detection is required.

Robust Construction. Accuflow low flow detectors consist of a rugged enclosure for

indoor and outdoor use. Like all System Sensor waterflow detectors, low flow models

operate across a wide temperature range, from 32ºF to 120ºF (0°C to 49°C).

Solid state retard assures precise

timing accuracy

Dipswitch selections simplify

retard settings

Reliable Performance. Accuflow low flow detectors are intended for applications

where flow detection of 3 GPM or greater is required. By incorporating a solid state

retard, proper sensitivity, timing accuracy and switch resetting is assured.

Non-polarized, two-wire design

allows connection to a local bell and

conventional or addressable systems

False Alarm Immunity. The solid state circuitry of Accuflow low flow detectors

provides greater timing accuracy over traditional mechanical retard designs. This

accuracy minimizes the risk of false alarms created by pressure surges or air trapped

within the sprinkler system.

NEMA 4 rated

Synchronized switches activate

both the alarm panel and local

bell simultaneously

Simplified Operation. Accuflow low flow detectors are designed to simplify installa-

tion. Wired like traditional waterflow detectors, these models do not require the

installer to run an additional third wire. Two conduit openings permit easy attach-

ment to the local alarm system.
