The receiver has 8 volt free relays which are conveniently brought out to screw terminals along the front edge of the circuit board and the expander board ESEM8 has the same features.
An external inhibit feature can be used to disable the alarm relays in groups or globally. Inhibit is also possible by using an ESF1 KeyFob and an ESEM8 module but it will reduce the number of outputs to 15. There are two additional relays which can be programmed to provide a grouped or global alarm output as well as day/night and global or grouped inhibit as required.
Easy programming is facilitated by way of an LED display and programming buttons. EPROM memory stores all learned devices and enables restoration of the alarm status in the event of a power interruption.
