The AA-30U Audible Alarm Extender Module is engineered to support a circuit for 24 Vdc polarized notification appliances wired in parallel. The number of devices you can connect varies based on the appliance type. Generally, the circuit can handle up to 20 vibrating DC bells, 10 DC horns, or strobe lights. You have flexibility to add more devices; however, the total electrical load must not surpass 1.5 amperes. To ensure safe and effective operation, always verify the current requirements for each connected device and ensure the combined load remains within the AA-30U's capacity.
