The System Sensor B524RB is a plug-in relay base for conventional 500 Series detectors. First, it adds Form-C relay switching to a detector head. As a result, the detector can trigger auxiliary control functions. For example, these include HVAC shutdown, damper control, and elevator recall. In addition, the plug-in design lets technicians swap a detector without rewiring.
System Sensor B524RB key features
- Works with any System Sensor 500 Series conventional detector.
- Provides one Form-C (SPDT) relay contact for auxiliary control.
- Plug-in base allows fast detector replacement and field service.
- Mounts to 3.5-inch and 4-inch octagon boxes or 4-inch square boxes.
- Suited to commercial, institutional, and industrial fire alarm systems.
Specifications
- Operating voltage: 15 to 28 VDC.
- Standby current: less than 500 microamps at 24 VDC.
- Relay rating: 2 A at 30 VDC resistive; 0.3 A at 110 VDC inductive.
- Operating temperature: 32°F to 120°F (0°C to 49°C).
- Operating humidity: 10% to 93% RH, non-condensing.
- Base height: 1.4 inches.
Therefore, installers gain reliable relay control in a compact base. However, confirm detector compatibility before ordering. Finally, pair the B524RB with the correct 500 Series head for your panel.
