The AA-30U Audible Alarm Extender Module is designed to provide a circuit for operating polarized, parallel-connected 24 Vdc notification appliances. The capacity of the circuit can vary depending on the type of devices connected. Typically, the circuit capacity is up to 20 vibrating dc bells, 10 dc horns, or strobes. However, additional devices can be added as long as the total circuit load does not exceed 1.5 amperes. It is important to check the current requirements of the connected devices to ensure that the total load does not exceed the specified limit.
