DSC PC4701 Alarm Control Panel Expansion Module

Ensure uninterrupted fire monitoring and robust emergency communications with the DSC PC4701 alarm control panel expansion module. Designed for commercial and institutional installations, this expansion module adds dual supervised phone-line connectivity to maintain reliable alarm reporting even if the primary path fails. The PC4701 expands detection with a 12-wire Class B/Style B supervised smoke alarm zone and a Class B/Style B waterflow zone, reducing wiring complexity while increasing coverage for large sites. Built-in fire alarm and fire trouble Form C relays offer flexible interface options for horns, strobes and building management systems, improving coordination between security, surveillance and life-safety equipment. FCC and UL approvals provide assurance for compliance-driven projects and simplify acceptance testing. Seamless MAXSYS compatibility lets integrators scale monitoring capabilities without replacing existing control panels, lowering overall lifecycle costs. Installers benefit from straightforward wiring and clear supervised reporting that reduce commissioning time and service visits. Ideal for schools, hospitals and multi-tenant buildings, the PC4701 enhances fire safety and alarm reliability—contact our sales team to integrate it into your security monitoring solution.
