Overview
Altronix ALSD2 2-Channel Siren Driver
The Altronix ALSD2 is a dual-channel siren driver designed to operate from either 6VDC or 12VDC power supplies, making it suitable for diverse security system configurations. This compact module drives two independent audio output channels with maximum current draw ranging from 0.3A to 1.22A depending on speaker impedance and supply voltage selection. The ALSD2 integrates directly into alarm control panels, fire systems, and access control infrastructure requiring synchronized or independent siren activation across multiple zones.
