| titleOfInvention | Alarm system |
| abstract | An alarm system comprising a pyroelectric sensor (1) of the single element type, electrical circuit means (2) operable to receive the output signal from the sensor (1) and provide an amplified output signal, audio alarm means (3) connected to receive the amplified output signal and be energised thereby, and power supply means (4) operable to supply electrical power to the sensor (1), electrical circuit means (2), audio alarm means (3) and power supply means (4) being mounted in an opaque but not fluid tight casing, and the electrical circuit means being electrically screened (7), whereby, in use, the pyroelectric sensor (1) is sensitive only to certain changes in pressure of the ambient atmosphere. |
