SW1 & SW2 are two switched outputs provided for connection to customer alarm
indicators, via relay contacts with 12V 500mA rating, configurable for either NO (Normally
Open) or NC (Normally Closed). These are marked as SW1 and SW2, and are in the form
of 2.5mm Jack Sockets. Plugs to fit these sockets are available from Comark, part number

With the Gateway switched OFF the relays are in a Normally Closed condition, this
