Product Information

The Howler HM4 Alarm is a popular alarm for large temporary accomodations like building sites where a large groups of howlers are connected (via 2 core fireproof cable) and a quick method of identifying the activated alarm to silence the very loud alarm is needed.

Due to the trace-a-lite feature the alarmed unit is verified via the illuminated light, this is used as a visual source of identifying the correct device rather then the audio 118dB siren which is issued by all the alarms,


With the 20cm outside diameter this unit is extremely small and easy to place!


118dB Alarm, very loud to ensure the alarm is dealt with swiftly.


Although very compact the HM4 draws the eyes easily with its bright red and bold white colour scheme.


The 9V PP9 battery makes sure the alarm is kept fully operational!


The Howler HM4 is supplied with a 2 year manufacturer's warranty period.
