The CWT alarm contains both a Room over temperature alarm and a water detection alarm.

The unit has been specifically designed to monitor critical areas such as a small server room, were both over temperature and a water leak would cause operational problems.

Complete with visual and audible indication, the unit can be connected to a Building Management System, remote beacon or send a Text message via the addition of our text messaging unit as shown in the “optional equipment” tab below.

The unit has been designed to monitor critical areas such as server rooms for water leak detection and room over temperature due to faulty cooling plant. Water is detected by using our leak detection cable that can be formed to any shape. Temperature is monitored via remote sensors. The temperature alarms trip point can be internally adjusted between 0 and 50°C. Room temperature is displayed on the alpha numeric display along with the alarm status. Also displayed on the screen is the water detection sensor alarm states. When the room temperature exceeds the alarm setpoint or the leak detection cable touches water, the display will flash showing the type of alarm, an internal audible waring will sound, the common alarm volt free contacts will change state, if fitted, the remote beacon/beacon sounder will start, and if fitted, the SMS text messaging/Email unit will send an alarm message via the mobile network. If power to the unit fails, the internal volt free “common Alarm” BMS contact will change state.

Features

  • Remote water detection sensor up to 100m away from the main alarm unit
  • Remote temperature sensors up to 100m away from the main alarm unit
  • Large back lit alpha numeric display
  • Current ambient temperature display
  • Tamper proof temperature alarm adjustment from 0 to 50°C
  • Except for mains power, all terminals are of the plug and socket type
  • On board audible warning device to alert local operators of a problem
  • Alarms latched until Mute operated to give indication of temperature fluctuations
  • Two common alarm relay contact for onward signalling to a BMS or other systems
  • Mains Power monitoring via the Common alarm BMS contact

The unit has been designed to monitor critical areas such as server rooms for water leak detection and room over temperature due to faulty cooling plant. Water is detected by using our leak detection cable that can be formed to any shape. Temperature is monitored and compared to an alarm trigger setpoint that can be internally adjusted between 0 and 50°C. The current ambient temperature is displayed on the alpha numeric display along with the alarm status. Also displayed on the screen is the current alarm states of the water detection sensor. When the room temperature exceeds the alarm setpoint or the leak detection cable touches water, the display will flash showing the type of alarm, an internal audible waring will sound, the common alarm volt free contacts will change state, if fitted, the remote beacon/beacon sounder will start, and if fitted, the SMS text messaging/Email unit will send an alarm message via the mobile network. If power to the unit fails, the internal volt free “common Alarm” BMS contact will change state.

Common alarm output to a flashing Beacon and Mutable Sounder

Beacon

SMS Text Messaging alert unit
For unmanned areas or to advise maintenance staff of a problem. With the addition of our SMS Text Messaging alert unit, an alarm will also be sent in text form to one or two phones. This unit is usually added where the alarm unit is mounted remote from maintenance staff, or in unmanned areas.
