The AA-30U Audible Alarm Extender Module supports a circuit for operating polarized, parallel-connected 24 Vdc notification appliances. The number of devices you can connect depends on their type and current draw. For example, you might connect up to 20 vibrating DC bells or 10 DC horns or strobes. However, the total circuit load must not exceed 1.5 amperes. Always check the current requirements of each connected device to ensure they remain within the AA-30U's specified limits for optimal performance and safety.
