Base Unit for Wireless Stand Alone Man Down Alarm System ISS0004090

Purchased 2 of the siren version of these (and 8 alarm units) for staff to use when conducting interviews, they are pretty much perfect for our needs, very discrete, we have them set to vibrate so as not to attract unwanted attentions should they be activated, the range is very good and covers our 3 story building with no problem and they were much cheaper than other less intelligent solutions. Very pleased will definitely buy more if we need them!
