Safe Signal Sprinkler EPS10-2 Pressure Control

For veteran contractors managing fire protection systems, the Safe Signal EPS10-2 pressure switch is the standard for monitoring waterflow in wet, dry, deluge, and pre-action sprinkler configurations. This alarm waterflow pressure switch features a field-adjustable 4-20 PSI pressure range, factory-set to trigger at 4-8 PSI on rising or falling pressure. Engineered with two SPDT relays (Form C), the EPS10-2 pressure control allows for simultaneous signaling to a fire alarm control panel and a local audible or visual notification device. The 1/2" NPT male connection ensures a secure fit directly into the alarm check valve or intermediate chamber. Built for reliability in demanding environments, the NEMA 4 rated weatherproof enclosure facilitates both indoor and outdoor installations. A reinforced bellows-activated diaphragm manages pressure spikes up to a 300 PSI maximum service pressure, maintaining a consistent 3 PSI differential to prevent false alarms during minor fluctuations.

Key Benefits

• Dual SPDT Contacts: Allows for versatile wiring of two separate alarm circuits or auxiliary functions.
• Precision Adjustment: Features a built-in sensitivity adjustment wheel for field calibration without specialized tools.
• Rugged Construction: NEMA 4 / UL 4x rated enclosure protects internal components from moisture and dust.
• High Compatibility: Standard 1/2" NPT connection integrates seamlessly with most existing riser assemblies.
• Resilient Performance: Designed to withstand system surges with a reinforced diaphragm and tamper-resistant cover screws.

Common Questions

How do I adjust the trip point on the EPS10-2?
Remove the tamper-resistant cover using the included key and rotate the adjustment wheel. Turning it counter-clockwise increases the pressure setting within the 4 to 20 PSI range.

Can this switch be used in outdoor applications?
Yes, the EPS10-2 carries a NEMA 4/IP54 rating, making it suitable for outdoor environments when installed with water-tight conduit fittings.

Does the EPS10-2 provide a delay to prevent false alarms?
This mechanical pressure switch activates immediately upon reaching the set point. For systems requiring a delay, it is typically paired with a retard chamber or a digital delay within the fire alarm control panel.
