15.7 A1466 Interface Relay
The A1466 Interface Relay board is available as an
optional item.
This relay is compatible with the Fire Signal Output
on the DUO-CEL panel. It provides two sets of volt-
free normally open & normally closed contacts.
Polarity and suppression diodes are also mounted
on the board.
The A1466 board should be mounted inside the
equipment to be controlled by the Fire Signal
output. The 10K EOL resistor should be connected
across the 24V & 0V terminals of the A1466 board..
