The Ani-Mate® animal friendly sounder uses a specifically developed low frequency tone (sub 400 Hz) that is designed to minimise discomfort to animals. The Ani-Mate® is designed to conform to the ‘silent’ fire alarm. The ‘silent’ fire alarm(1) was developed because of the need for an effective alarm signal in laboratory animal facilities which did not stress the animals every time it was tested. Small mammals in particular can be distressed by the frequency of tones emitted by standard electronic sounders and bells. It is only by using a conventional cone loudspeaker that pure low frequencies can be reproduced and thus disturbance to animals be minimised.
The LF-DB-LI isolating base is intended for use with the LF-6100 Series detectors. The LF-DB-LI isolating base senses and isolates short circuit faults on LF-6100 loops and spurs. In short-circuit conditions the integral red LED is illuminated.
