The very 1st line that is programmed as a host
controlled output is considered “Relay

When a line is programmed as an alarm or pulse

any one of the output lines, within the frequency limits of the CNI2. This allows other pulse
sensing equipment to have access to the same information. For instance the
CNI2 may be counting pulses and there may be another p
iece of equipment located nearby that
needs to count these pulses too. The CNI2 can be programmed to transmit a replica of the
input signal to this other piece of equipment.
To use this feature select the desired output line. Then from the selection lis
