Alarm Outputs
SW1 & SW2 are two switched outputs provided for connection to customer alarm indicators, via relay contacts with
24Vdc 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 can be ordered from Comark
Instruments using part number: RFJACK.
With the Gateway switched OFF the relays are in a Normally Open condition, this may cause any equipment
connected to the contacts to energise.
