» Multifaceted Environmental Alarm:  OGW 

The OGW Environmental Alarm Systems are designed to monitor computer rooms, server rooms, plant rooms or other critical technical areas to provide combined security against damage caused by water leaks, overtemperature, over humidity, mains failure,  fire etc. - all in one unit , which can optionally telephone remote locations identifying which alarm has triggered. The OGW Control System is available in three cabinet sizes, 1 to 8 alarms/zones, 1 to 16 alarms/zones and 1 to 32 alarms/zones, and can be made to the specific number of zones required.

The OGW Unit can be used as a single or multizone OVERTEMPERATURE ALARM SYSTEM monitoring from adjustable Tamperproof or Digital Readout Temperature Sensors rated for temperature band 0 to 35°C. HUMIDITY MONITORING would be from adjustable Humidity Sensors rated for humidity band 30-100 %RH. WATER LEAK DETECTION can be provided from either Linear Sensor Cables or Tape, or from Spot Pad or Probe Sensors. Aqualeak manufacture a range of specialised Sensors including OIL LEAK DETECTION Probes. FIRE DETECTION would be from an independent Fire Detection Sensor linked to and powered directly from the OGW Unit. MAINS FAILURE would be monitored from an internal mains failure module.

When any room environmental condition reaches an alarm state, the appropriate zone light on the Controller would illuminate. The horn would sound and can be muted, but the zone light remains on until the alarm is cleared. Two ‘Common Alarm’ relays are provided for remote alarm and shutdown purposes. Optional Individual Zone Signalling Relays, optional Mains Fail Relay and optional Battery Backup is also available. 

The Control Unit can be inside or remote to the monitored area and would be linked to the Sensors by Leader Cable. The OGW System can be provided with an optional analogue Autodial which can ring home in the event of problems and advise which alarm has triggered. An optional Repeat Alarm Unit can also be provided to be located remotely to provide audio/visual alarms elsewhere.
