Information About 565-256
The 565-256 is a Simplex Power Input/Output Interface assembly developed specifically for later configurations of the 4020 fire alarm system. Its electronic circuitry interfaces with the 636-341 Universal Switcher Power Supply and converts the incoming 28.5-volt direct-current supply into the regulated voltages required by internal system electronics. The board is designed for use with the 565-368 Standard Slave printed circuit board and the associated system software configuration. In addition to power conversion, it performs power-supply supervision, voltage and current monitoring through an analog-to-digital converter, trouble monitoring, tap voltage control, and ground-fault detection.
Key Features:
- 4020 System Compatibility: Designed as a power supply interface assembly for the Simplex 4020 fire alarm control panel platform.
- Power Supply Interface: Interfaces with the 636-341 Universal Switcher Power Supply used in the corresponding 4020 system configuration.
- Voltage Conversion: Converts approximately 28.5 volts direct current into +5-volt and +36-volt supplies required for internal system functions.
- Power Supervision: Provides the interface used by the control system for supervision and control of power-supply operation.
- Voltage and Current Monitoring: Incorporates analog-to-digital conversion for supervision of power-supply voltage and current conditions.
- Ground-Fault Detection: Performs ground-fault monitoring as part of the 4020 power-management architecture.
- Configurable Power Taps: Uses jumper selections to enable the main system supply and designated power taps required by the panel configuration.
- Standard Slave Compatibility: Specifically pairs with the Simplex 565-368 Standard Slave printed circuit board rather than the earlier 565-222 configuration.
The 565-256 delivers the reliability and precision required for power conversion, supply supervision, fault monitoring, and internal power distribution in compatible Simplex 4020 fire alarm systems.
