• Panic Alarm Systems (Hard Wired)

    High integrity platform for added safety and peace of mind

Attack Alarms and Panic Alarm Systems – Designed Specifically for Safety & Peace of Mind in the Workplace

Zettler Attack Alarms & Panic Systems are Synonymous for Quality

Our Alarm Button Systems and attack alarms are installed in over 500 premises in the UK alone that enable a call for assistance where required. Our range of ZETTLER panic alarm buttons are absolutely ideal for often harsher working environments.  Call systems in higher security facilities, such as psychiatric facilities, require the implementation of advanced features to protect against vandalism and to provide accurate monitoring and reporting options.

Applicable Sectors

Along side a staff attack alarm for hospitals, examples of sectors where our attack alarms and commercial panic alarm systems are employed include psychiatric hospitals, care homes, prisons, police custody suites, magistrates’ courts, detention,  and remand centres. Our range delivers worry-free emergency panic button communications for these environments using discreet ceiling mounted receiver units.

Robust Solution – To Feel Safe & Secure

Physically, these wired panic alarm systems are purpose designed to be tough and reliable whilst remaining user friendly. Our call panels all include ultra-safe ZETTLER circuitry monitoring that’s constantly being polled by the system for peace of mind that the system is working optimally and that the response time is met. Where wiring is not an issue, it offer significant advantages over a purely wireless system. So if you’re considering a system such as medicare, aidcall or courtney thorne – give us a call. Calls go to colour coded display units – no need to peer at text any more.. a red screen means what it says and everyone knows.

User Friendly Options

At one end of the scale, a client may just be looking for a simple attack calls using a stainless steel plate unit. They may also require a key switch operation with led reassurance lamps and audible tones. Typically, these would be fitted with anti-tamper screws and a reassurance lamp too. Sometimes the unit would have to be fitted in a swimming pool as a distress alarm. In this case, and IP 65 rated version may be required. Staff protection systems in psychiatric hospitals will often also require additional facilities such as ‘presence’. In this case, staff attending a room to answer a call will press the green ‘presence’ button on the stainless steel unit, which will alert colleagues to the fact that they have entered the room, also enabling a second higher level of call. They may also want speech versions too to facilitate speech between staff and patients via a mobile phone. It may also be desirable to add staff attack receivers, personal activation devices, an sos button and real time location features – all of which is possible with our range to deliver peace of mind to members of staff or a single staff member at either the control panel or on the move. We can also supply long range dual technology pagers too.
