Well designed are SEP’s GSM Ultra Alarms this one got a real bashing this week in a large property in London but the intruders couldnt finish it off it kept signalling to the monitoring centre.

‘Ouch’ our Ultra Alarm bashed at a break-in ‘still works’

We will put it in a new steel security galvanised designed box and it will be ready for rental again in a couple of days ‘bring it on’.
