| DDD
provides a wide range of panic attack alarm systems utilising
equipment for both wired and wireless technology. A wide range
of transmitters and receivers are available which are easily
combined to meet your specific applications. |
|
All of our radio systems operate on FM narrow band and all transmitters
and receivers are crystal- controlled
with a dual conversion superheat featuring crystal and mechanical
filters. The result is a |
highly
selective radio system which ignores any unwanted signal, and
decodes signals more reliably than any competitive system.
Systems can also be designed, more especially for lone worker
or high risk applications that when activated can transmit signals
to our Alarm |

or other nominated assistance as required. |
