CruzPro LA20 External 105 dB Multi-Alarm

The LA-20 External Multi Alarm has five alarm input terminals and connects up to five instruments to provide an amazing loud 105 dB alarm volume that can be heard for 1/4 mile or more. A built-in light flashing circuit will flash spreader, running or anchor lights drawing up to 8 amps. The LA-20 External Multi Alarm has five alarm input terminals and connects up to five instruments to provide an amazing loud 105 dB alarm volume that can be heard for 1/4 mile or more. A built-in light flashing circuit will flash spreader, running or anchor lights drawing up to 8 amps. All five inputs terminate on screw terminals making connections easy and require only a screwdriver.

Four of the five alarms can be silenced by pressing the RESET button, one purposely bypasses the RESET button and must be turned off at the source (good for security alarms).

Two different types of inputs are provided. Three inputs activate the alarm if any one of them are grounded or go below 5 VDC. The other two inputs activate the alarm if one of them goes high (+2 to + 33 VDC). One of the latter bypasses the RESET button (cannot be turned OFF at the LA-20).

If the LA-20 is silenced by pressing the RESET button, it automatically re-arms itself when all the inputs are in a clear state.
