Potter Electric Signal Co. Us DPS-50 Differential Pressure Switch

Product Description

The POTTER ELECTRIC SIGNAL CO. US DPS-50 is a differential pressure switch designed to monitor pressure differentials across system components in fire protection, HVAC, and related building systems. It detects changes in pressure between two points and triggers an electrical signal when a set threshold is crossed. Licensed fire alarm and mechanical contractors install this type of device as part of notification and monitoring assemblies. The DPS-50 serves as a notification accessory, integrating into control panels or monitoring circuits to provide status indication or alarm output based on system pressure conditions.

The DPS-50 is suited for commercial and light industrial applications where pressure monitoring is required as part of a notification or supervisory system. Typical installations include air handling systems, fire suppression monitoring circuits, and HVAC duct pressure applications. It is sold in single-unit quantities and is classified as a notification accessory within the broader category of fire and building system components.

Key Features

• Monitors differential pressure to trigger notification or supervisory signals
• Designed for use as a notification accessory in fire protection and HVAC systems
• Single-unit packaging for straightforward procurement
• Electrical output suitable for integration with control panels and monitoring circuits

Compatibility

Designed as an OEM-style replacement or direct installation component for differential pressure monitoring applications in commercial fire protection and HVAC notification systems.

Installation Notes

Installation of differential pressure switches should be performed by a licensed fire alarm technician, mechanical contractor, or qualified HVAC professional in accordance with applicable local codes and NFPA standards. De-energize the system and relieve system pressure before connecting or disconnecting the switch. Verify all electrical connections meet NEC requirements before restoring power. Consult the system control panel documentation to confirm switch wiring and setpoint configuration.
