Permalert FluidWatch FW25-50 Manuale operativo

The FluidWatch®Leak Detection

System has been engineered to

monitor small areas for water leaks.

Typical applications include

unmanned equipment rooms, small

raised floor areas, and small tanks.

The system continuously monitors

the capacitance of the sensor cable

and detects changes from the initial

value.

FluidWatch can be powered by 120

VAC, 240 VAC or 24 VDC. Just

seconds after the coaxial sensor

cable contacts water or water-based

liquids, the unit enters into alarm.

The sensor can be quickly dried in

place after the leak is cleaned up

and the system put back on-line.

The FluidWatch system uses an

LED "traffic light" display to indicate

status: Green - system normal,

Yellow - sensor cable break; and

Red - wet cable or a short. The alarm

unit activates an audible alarm and

10 A, 250 VAC, SPDT relays when

either a leak or break occurs. There

are two operator buttons. One is

used to test the system periodically

and the other to silence the alarm.

The silence button can be disabled

via an internal switch to prevent

unauthorized alarm silencing. There

is an internal adjustment to select a

desired alarm threshold from several

inches to several feet to suit any

application. Another internal switch is

used to select whether the system

will silence the alarm automatically

upon cable reset or require an

operator to push the silence button

manually.

FluidWatch is available with three

sensor cable lengths or as a special.

Each model comes complete with a

monitoring unit, jumper cable and

sensor cable, cable mounts, and

cable tags. All cable connectors are

factory installed. The sensor string

can be mixed lengths of jumper and

sensor for monitoring multiple areas.

PART 1 • SYSTEM

1.1

The FluidWatch Leak Detection

System shall consist of an electronic

monitoring unit, coaxial water-

sensing cable, interconnecting

jumper cable, cable mounts, and

identification tags required for a

typical installation. All cable

connectors shall be factory installed.

The system supplier shall have ten

years of experience in the

manufacture of the leak detection

systems.

PART 2 • COMPONENTS

2.1

The monitoring unit shall be able to

monitor one length of sensing cable.

Three LEDs shall be visible on the

door of the unit indicating System

Monitoring (Green), Leak Detected

(Red), or Wire Break (Yellow). The

unit shall have an audible alarm and

be equipped with four SPDT Form

1C relays having contacts rated for

10A continuous @ 250 VAC.

A Power/Fault relay shall be normally

energized when the system is

powered and deactivate after a loss

of power. The audible alarm and

relays shall be activated in the event

of a leak (2 relays) or a continuity

fault (1 relay).

The system sensitivity shall be easily

adjusted several inches to several

feet of wet cable.

The system shall have two switches

for operator input: test and alarm

silence. Internal jumpers shall enable

the silence button and enable

automatic silence after the cable

resets. Internal switches select

AC/DC operating voltage.

The monitoring unit shall be powered

by [120 VAC] [240 VAC] [24 VDC]. It

shall be housed in a nonmetallic

enclosure with nominal dimensions

of 7ʺx 7ʺx 3ʺ.

2.2

The standard sensor shall be a

coaxial cable consisting of an

insulated center conductor, water

permeable dielectric core, and outer

braid conductor.

The sensing cable shall have the

ability to detect the presence of

water at any point along the cable's

length. The cable shall be easily

field repairable, flexible, and carry

less than 6 VDC under normal

operating conditions.

2.3

The system shall include one

monitoring unit, one length of

sensing cable, one 25 ft (7.5 m)

jumper cable to connect the sensing

cable to the monitoring unit, one

cable mount for every 5 ft (1.5 m) of

sensing and jumper cable, and five

cable tags.

PART 3 • INSTALLATION

3.1

All FluidWatch system components

shall be installed in accordance with

the manufacturer's installation

instructions.

3.2

The monitoring unit shall be installed

and powered in accordance with

NEC and local code requirements.
