Talking Alarms
Amber Valley is a specialist manufacturer of talking alarms
Probably the safest type of warning system because of its unique directional qualities and the ability to say exactly what the danger is.
These alarms are available as standalone alarms such as, “Stand well clear, vehicle reversing,” to complete systems where we provide the complete solution.
The most popular examples are:
“Handbrake not applied” – which is activated when the driver’s door is opened and the handbrake is not on. It works regardless of whether the ignition is on or not.
Seatbelt alarm – there are several systems in our range for this alarm, one which gives the message twice when the bus door closes, the second time louder and with more authority. Ideally suited to school buses.
“Diesel fuel only” – this is becoming more popular, especially on light commercial vehicles. When the fuel flap is opened the alarm says, “Diesel fuel only,” as putting petrol into a diesel vehicle costs thousands of pounds.
Bespoke messages in any language
All we require is the message in any language in a WAV file to be emailed to us and we will make the required alarm, usually within 2 to 3 days, using the exact message and voice as we receive it. This is especially important in English speaking countries where accents are critical. After all, a New Zealander or Australian does not want a message in an Oxford English accent as the local people would not immediately respond to it.
dB level
The dB level shown for the talking alarms denotes the speech level and not the beep dB, which will be higher.
All of our units are speaker driven which most people agree is the best option for a sounder and all of our speakers are Mylar (plastic) cone with a solid metal back, making full encapsulation simple and thereby making a totally sealed unit.
