Altronix ACM4 4-Output Access Power Controller

Altronix ACM4 Access Power Controller, 4 Fused Relay Outputs

Overview

The Altronix ACM4 is a multi-output access power controller that converts a single 12 to 24 VAC or VDC input into four (4) independently controlled fuse-protected relay outputs. Each output can be converted to dry form "C" contacts, making it suitable for routing power to magnetic locks, electric strikes, magnetic door holders, and other access control hardware. The ACM4 operates in both Fail-Safe and Fail-Secure modes and includes a Fire Alarm Control Panel (FACP) interface for emergency egress and alarm monitoring.
