FPT 50T – Fire Service Water Tank Level Control w/ High & Low Alarms, 40F Temperature

FPT50T – Fire Service Water Tank Level Control w/ High & Low Alarm, 40F Temperature

Complete Kit Includes:

NEMA4x Control Panel
Sensor w/ 50 ft. Cable
Sensor Mounting Assembly

Features

  • Dry contacts to BMS for measuring Fill “ON” time
  • Low Water Alarm
  • High Water Alarm
  • Temperature 40F Indication (per NFPA requirements)
  • Fault conditions
  • Operates 110VAC Solenoid Valve
  • 110VAC 95db Audible Alarm w/ Silencer Switch Installed in the Panel

Description

The system is automatically controlled within an operating range (this range can be set by custom ordered probes or cutting the current probes to length in the field). The system also monitors for a high water level condition and a low water level condition.
These conditions have three outputs each which are:

  1. Close a set of dry contacts for the BMS
  2. Operate a relay rated at 30AMPS / 250VAC
  3. Turn on an LED to indicate the sensor has tripped

The Fill dry contacts can be used as a comparative to develop a baseline benchmark of water usage for the system.

Custom Sensors lengths available upon request.

Altitude Valve

Replace Altitude Valves with Modern Controllers

Replace Altitude Valves with Modern Controllers

Many ground level or elevated water storage systems use what is known as an Altitude Valve. These valves close at a preset high-level to prevent overflow of water in a ground storage tank or reservoir, opening to refill the water in the tank or reservoir as the level lowers. In crude systems they are reliable and effective.

Modern water storage requirements are not usually well served by such stand-alone devices though.

Fire Safety Water Holding Tanks

For fire protection, a much more effective, less temperamental and less expensive solution is an electronically operated system that connects to automated building management systems, has alarms, or even redundant switching and alarms.

FPT50 ControllerA better solution for Fire Safety holding tank systems, and a replacement for them, is the Waterline Controls WLC FPT-50. This Fire Service Water Tank Level Control with high and low alarms gives you modern, state of the art control, visible and audible alarms, and peace of mind.

Elevated Reservoirs that use Altitude Valves can benefit from our SWS5000 Control System.

Our systems come with a modern, intrinsically safe, electronic sensors.
Our systems connects to a BAS or building management system for many modern code requirements, or just logical safety precautions.

Fire Protection Water Tank Level Controller System

Fire Protection Water Tank Level Controller System

Fire SafetyYour Fire Protection System is dependent on assuring your water reserve requirements are met at all times:

You really need look no further than the revolutionary
Electronic Sensors and Solid State controllers from Waterline Controls

Fire Water TankTypical regulations usually include languarge such as:

Regardless of use, all tanks shall be equipped with a device that will ensure that the tank contains the designated amount of water for fire flow duration as determination by the fire department”

Water Storage Tanks are an integral part of fire protection systems and the use of an above ground water storage tank that is correctly sized for the application could make the difference in an emergency situation and may be required by local fire code as a secondary on-site water supply for automatic fire sprinkler systems also known as a break tank.  A break tank is a water tank providing suction to a fire pump, but the tank’s capacity or size is less than that required by the fire protection systems served.

Water Tank Level Controller High Water Alarm

Water Tank Level Controller High Water Alarm

Our water supply system and its infrastructure are intended to plan for the collection, storage, distribution and transmission, including treatment, of water for homes, commercial use for industry and irrigation, as well as for such public uses as fire fighting.

All of these uses require reserve water or a guaranteed supply of water to operate. The normal solution is a water holding tank at or near the place of intended use. In domestic supplies, this might be a municipal water tank or resovoir. Many municipal systems are required to keep a minimum of at least 30 days supply ‘banked’ in underground or above ground systems.  This aspect, along with several other aspects of water management falls under civil engineering services provided by the local county or city government in charge of managing the water systems.

Rooftop Water TanksMany rural areas are on private or local wells. In many residential areas with low yield wells (typically less than 5gpm but it is sometimes considered as a function of requirements) an elevated holding tank is a requirement. The long familiar sight of high rise inner city buildings with water tanks on the roof, in use today, provides high-rise residents the water from those tanks located on the roofs of the buildings. In addition to being a storage device the tank creates water pressure by gravity, which brings water to each apartment as needed. They can also potentially provide fire safety in those high rises by providing instant local access to water.

Safety

For most commercial and fire saftey systems the common storage solution is a holding tank. Both cooling towers for HVAC and storage tanks for fire supression must have a reliable system for regulating the water level. Amazingly, many safety systems still have old fashioned float type switches or early generation electric water level switches. The first forms of electric sensors did improve on the mechanical float switch, while introducing new problems to be learned and overcome, such as corrosion or deterioration of sensors rendering them inaccurate or useless. In the cases of power failure there are other issues with the loss of electricity itself at the site.

Conservation

Potable water is the essence of life. Wasting it is not an option in our society today. Our work with local utilities shows how properly regulating water levels does indeed save water and money.

Recently, we added a Normally Closed (NC) relay to a high alarm and wired the well pump through the relay; when activated the relay would open and turn the pump off. This is a safety switch just in case the relay that operates the pump contacts fuses closed. We can custom fit almost any application.

Legal Requirements

A High Level Alarm or shutoff is a water conservation device to conserve water waste, damage from spillage, etc. In California, the law changed a year ago and now requires not only that all cooling tower systems have both a shutoff and an alarm, but must report to a BAS: “Open and closed circuit cooling tower installations must … be equipped with an overflow alarm to prevent overflow of the sump in case of makeup water valve failure….alarm shall send an audible signal or provide an alert via the energy management control system to the tower operator in case of sump overflow.”

Our integration with BAS, our UL listing and our rock solid reliability backed by our exclusive 100% guarantee is reason enough to employ Waterline products in all your water level management applications. When you realize the simplicity of maintenence, advanced state-of-the-art system operation and advanced microprocessor control finally gives you what you want at a cost that is exceptionally reasonable, you will wonder why you haven’t made the step up to waterline controls before.
