GuardEx system provides high-reliability guarding, alerting and calling signalization, with flexible access control capability, could be applied for small as well as huge objects (for example: hotels, plants, offices, multi-storey garages.) Maximal modules amount: 600.
Principle of operation:
All input-output devices are connected together serially with one-pair signal wire. First and last are connected to the computer, thereby they form loop of modules. If happens that module lost connection with the computer, it begins to work offline, providing undisturbed operation of access control system.
One of module release versions for hotels has an algorithm, developed by hotel security service: each module has connection with one card reader, door-open sensor, capacity sensor, lock-open sensor and electrical door lock. Module provides twenty-four-hour door protection, personal and guest access and looks after door could no be open for a long time.
The computer, with installed GuardEx software, is used for system programming and monitoring.
