| Description The AMACS GSM is an add-on panel that provides remote, mobile phone based control of essential equipment. The system may be used in a range of vital applications:- • Water level and irrigation control • Prompt, automatic warning of plant faults • Unauthorised entry/intrusion • Vehicle theft • Electrical equipment trip operation Operation At the heart of the AMACS system is a GSM data modem that allows text communication between the panel and a mobile phone. By sending SMS text messages from a mobile phone, a remote operator is able to configure the AMACS panel, request plant status information and operate the panel's relay outputs. The two volt free relay outputs may be used to control remote equipment, e.g. to give engine or pump starting, valve operation, fault reset, etc. Remote text commands allow the outputs to be turned on, turned off, or give a 5 second 'pulse'. The AMACS panel also has two inputs that can be activated by switch or relay contacts in the remote equipment, e.g. after an automatic engine start, or following a fault condition or other event. The inputs can be independently set so that activation or de-activation of each input causes the AMACS to send an appropriate, pre-programmed text message to the user's mobile phone. The AMACS system is housed in a robust, lockable enclosure complete with a screw-fitted arial. Cable access is through a plate in the panel base: when used with correct glands, the panel is environmentally sealed to IP54. |
