SFA4
Description
The SFA 4 Auto Dialler system provides when fault occurs, automatic telephone dialling of pre-programmed numbers. There is an adjustable time delay between the commencement of a fault and the starting of the Auto Dialling Sequence. When a fault occurs due to a mains failure or over temperature etc. Either relay or thermostat contacts within the alarm circuit will open. This will immediately cause activation of the hooter or flashing beacon. after an adjustable time delay (maximum 3minutes) the Auto Dialler will activate and inform a central station that a fault has occurred at your specific location. If the fault is due to a complete mains failure the SFA4 will still function due to its own internal power source provided by a rechargeable battery.
