Product Overview

SNDEXT-4 has been deisgned to provide a sounder circuit extension solution. The card has 4 monitored and fused sounder cicuits. There are switched negative inputs to trigger all circuits (common) or each circuit individually, a relay is also provided for remote fault monitoring. The fault relay will operate for all faults including loss of 24v supply input.

The card is driven from an existing sounder circuit in the control panel. A permanent 28v supply is required. If used with a Haes conventional control panel, this supply can be taken from the 28v output on the main circuit board.

Each circuit is fused at 0.75 amp via self healing fuses and requires a 4K7 end of line monitoring resistor (provided).
