Description
SD-202GS Wired Alarm
The OEM SD-202GS Gas Detector provides reliable combustible gas monitoring for commercial and industrial security networks. This hardware integrates a high-stability semiconductor sensor to detect Liquefied Petroleum Gas (LPG) and Natural Gas. It functions as a standalone unit or connects to a central control panel via wired relay outputs. The device utilizes a high-sensitivity semiconductor sensor. This sensor detects coal gas, methane, and propane specifically. The internal processor manages signal stability. It filters out false triggers caused by environmental humidity or minor temperature fluctuations.
Key Features
Dual-Mode Operation
The unit supports standalone audible alerts and networked relay signaling for integrated security systems.Integrated Relay Interface
- Normally Open (NO) and Normally Closed (NC) contacts
- Automatic triggering of external ventilation fans
- Solenoid valve control for gas supply shut-off
High-Decibel Audible Alert
An internal siren produces over 85dB at one meter to ensure immediate local notification.Advanced Sensor Protection
Surface Mount Technology (SMT) fabrication increases circuit density and protects against radio frequency interference.
The hardware manages a warm-up period during initial power-up. An internal timer prevents false alarms during this three-minute stabilization phase. The 10% Lower Explosive Limit (LEL) threshold provides a significant safety margin. This level remains well below the concentration required for ignition. High-intensity red LEDs provide immediate visual confirmation of an alarm event. Green LEDs indicate stable power supply. Yellow LEDs signal a sensor fault or end-of-life condition. The terminal block accepts standard 18AWG to 22AWG security wiring. This ensures secure physical connections for long-distance cable runs. The housing uses high-impact ABS plastic. This material resists structural degradation over time.

Why Choose SD-202GS Wired Alarm
Standardized relay outputs allow seamless integration with global security panel brands.
The auto-reset feature eliminates manual intervention after gas concentrations return to safe levels.
High-sensitivity components detect leaks before they reach dangerous combustion thresholds.
Reliable SMT manufacturing ensures consistent performance in varied commercial environments; consequently, maintenance requirements remain minimal.
Josphat Mwangi (verified owner) –
We installed several of these SD-202GS units in our restaurant kitchen in Westlands. The alarm is quite loud, which is exactly what we needed so the staff can hear it over the noise of the extractors. It feels sturdy for an OEM unit and gives us a lot of peace of mind regarding safety. Shipping to the CBD was very fast.
Grace Atieno (verified owner) –
I prefer these wired models over the battery ones because you don’t have to keep checking if the cells are dead. Using it in our apartment block in Syokimau and it triggers quickly when tested with a bit of gas. Solid build quality for the price.
Kelvin Kibet (verified owner) –
Exactly what I needed for my workshop. Simple, effective, and reasonably priced. Asante.
Fatuma Hassan (verified owner) –
The detector itself is very sensitive and works well, but setting up the wiring took a bit longer than expected because the included instructions were a bit brief. Once it’s powered up though, it works perfectly and detects leaks immediately.
