ROOM TEMPERATURE ALARM - OVER TEMPERATURE ALARM - HEAT EXTREME SENSOR

HES-01 is a precision temperature measuring sensor that controls an integral radio transmitter. The calibrated sensors are available in two standard preset temperatures; 28°C and 32°C. The preset temperature for on-line purchase is 32°C, which is considered harmful to health. When the room temperature reaches the preset alarm temperature the transmitter transmits a signal that is received by any of the following control receivers:

REMOTE CONTROLLED MAINS POWER SOCKET - AUTOMATICALLY SWITCH ROOM FANS ON TO COOL THINGS DOWN

RADIO RECEIVER WITH RELAY OUTPUTS - CAN BE USED TO TRIGGER A TELEPHONE AUTO DIALLER TO RAISE A REMOTE ALARM OR TO CONTROL OTHER DEVICES REQUIRING A SWITCHING SIGNAL

When room temperatures rise to dangerous levels to vulnerable people, the HES-01 could be a life saver

The illustration on the right shows a temperature sensor, mains control socket and a control socket with a fan plugged in. The socket is normally off. If the room temperature rises to the switching temperature of the sensor the built in transmitter sends a signal to the socket, which in turn switches the fan on. The sensor transmitter can operate in two ways: 1. By sending an on signal, fan will be switched off automatically when the room (sensor) temperature falls by 2°C below the sensor preset level. 2. The transmitter has a timer that can be set by switch to automatically send an off signal. Settings from 30 seconds to 20 minutes. The control socket can also be manually switched on/off using a key fob transmitter.

MAINS POWERED CONTROL RECEIVER

The mains powered receiver can also receive signals from the temperature sensor or key fob transmitter. The receiver controls an internal relay, which can switch mains voltage or provide clean contacts with normally open and normally closed contacts. The receiver can be used to directly control a fan or be used to trigger a telephone auto dialler. When temperature extremes may affect people, animals or sensitive equipment, the dialler will provide an off-site alarm.

Temperature sensors are available for rising temperatures from 8°C ~ 50°C

Sensors are also available to warn of falling temperatures. Please enquire for further details.
