DSC PC4204 MAXSYS Power Supply/4-Relay Output Module

Built for commercial intrusion and access control environments, the DSC PC4204 MAXSYS Power Supply/4-Relay Output Module provides reliable, supervised auxiliary power and flexible relay control to keep security and monitoring systems operational. As a DSC MAXSYS relay output module, the PC4204 offers four programmable Form C relays rated at 2 A @ 30 V DC, enabling direct control of locks, gates, alarm annunciators and other external devices. Relay 1 can be configured to repower the COMBUS, restoring communications quickly after a fault. The unit supports up to 16 modules and can be installed up to 1000 ft from the control panel via COMBUS, simplifying wiring runs in larger facilities. Fully supervised for AC failure, low battery and AUX faults, this module helps maintain compliance with commercial monitoring standards while reducing false alarms and unexpected outages. Compatible with DSC cabinets like the PC4051C/CR and PC4052C/CR, the PC4204 integrates seamlessly into existing MAXSYS installations. Ideal for security integrators and facilities managers who need dependable, monitored power and remote device control—specify the PC4204 for intrusion, surveillance and access control projects or contact your DSC distributor to order.
