Find My Replacement Detector
Identify your existing RV gas detector to find the right SENSYX direct-fit replacement.
Most common replacements
Safe-T-Alert 20-441 series → SRC2000-S
Both surface-mount, both dual-gas (propane + CO), same wiring (12V hardwired). The SENSYX SRC2000-S adds a digital LCD showing real-time gas concentration during an alarm — Safe-T-Alert 20-441 only shows red LED.
Safe-T-Alert 25-741 series → SRC2000-S
Same as 20-441 above — surface-mount dual-gas. SRC2000-S is the direct-fit upgrade with LCD readout and 75 ppm CO pre-alarm (Safe-T-Alert alarms only at 150 ppm).
Safe-T-Alert 30-442 series → PRC2000
Flush-mount dual-gas. The SENSYX PRC2000 is the corresponding flush-mount model from the same engineering line as the SRC2000-S.
Atwood Series 30 → SRC2000-S or PRC2000
Atwood discontinued the Series 30 line, so all replacements must move to a different brand. SRC2000-S replaces surface-mount Atwood units; PRC2000 replaces flush-mount. Read the dedicated Atwood replacement guide →
Briidea LP/CO → SRC2000-S
Surface-mount dual-gas. The SENSYX SRC2000-S adds: LCD readout, 75 ppm CO pre-alarm (Briidea alarms only at 150 ppm), and disclosed UL-Recognized FIGARO sensor (Briidea does not disclose sensor source).
