Frequently Asked Questions

What is the Fireye 25SU3 Flame Signal Amplifier used for?

The Fireye 25SU3 Flame Signal Amplifier is used in industrial burner management systems to amplify and discriminate flame signals from Fireye scanners such as the 45UV5, 45RM1, 45RM2, 45RM4, and 45FS1. It maximizes burner discrimination by accurately differentiating pulse rates, ensuring reliable flame detection and safety in combustion applications.

What are the specifications of the Fireye 25SU3-2100?

The Fireye 25SU3-2100 is a flame signal amplifier in the 25SU3 series, FM Approved. It operates with a 19" adapter model 192SU3-2120 (120 VAC) or 192SU3-2220 (220 VAC). It is compatible with Fireye scanners and plugs into existing 60-1706 racks for easy field upgrade from older 25SU3 controls.

Where to buy the Fireye 25SU3-2100 in Singapore?

You can source the Fireye 25SU3-2100 Flame Signal Amplifier through 3G Electric in Singapore. We supply this Fireye component and handle logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this model.

How to install the Fireye 25SU3-2100 with the 19" adapter?

To install the Fireye 25SU3-2100, use the appropriate 19" adapter (192SU3-2120 for 120 VAC or 192SU3-2220 for 220 VAC). The adapter plugs into the existing 60-1706 rack and is electrically and mechanically compatible, so no wiring changes are typically needed. Ensure power is off before installation.
