Gas detector SATEL DG-1 TCM — wall-mounted, white, 97×97×36 mm, 105 mA power consumption

The SATEL DG-1 TCM is a wall-mounted gas detector designed for continuous monitoring of narcotic gas vapours in residential and small commercial interiors. Housed in a white enclosure measuring 97×97×36 mm, the detector is intended to detect hazardous concentrations of heavier-than-air narcotic gases such as trichloromethane. The unit operates with a supply current of 105 mA (standby 85 mA) and combines a microprocessor-based detection algorithm with temperature compensation and self-diagnostics to maintain reliable performance across a range of ambient conditions.

Advantages

The DG-1 TCM provides digital signal analysis and temperature compensation to reduce false alarms and ensure accurate detection of narcotic gas concentration thresholds. Built-in self-diagnostics continuously monitor supply voltage and sensor performance to support dependable operation. Visual and acoustic indication — a blue LED and an internal buzzer — enable both standalone alarm signalling and integration with a wider alarm system. The compact, low-profile housing and low current consumption make it suitable for permanent wall mounting in occupied spaces.

Suitable for

• Bedrooms and sleeping areas where narcotic gas use is a concern
• Watchman lodges, security quarters and guard rooms
• Small offices and residential corridors requiring continuous vapour monitoring
• Integration with alarm systems as a dedicated narcotic gas sensor

Key specifications

• Mounting: wall-mounted, low-position installation recommended (near floor) for heavier-than-air gases
• Dimensions: 97 × 97 × 36 mm
• Colour: white
• Operating principle: microprocessor-based detection with digital signal analysis and temperature compensation
• Indicator types: blue LED visual indicator and built-in buzzer for acoustic alarm
• Power consumption: 105 mA operating, 85 mA standby
• Functions: continuous monitoring, threshold alarm triggering, full autodiagnostics (sensor and supply supervision)

How to use

Install the DG-1 TCM on a wall at a low position just above the floor level of the monitored room, since narcotic gases are heavier than air. Connect the detector according to the alarm system or standalone wiring instructions provided by the manufacturer, ensuring correct supply voltage and secure mounting. After power-up the detector performs self-diagnostics; confirm that the blue LED and buzzer operate as expected during initial testing. Place the unit in locations where airflow is representative of the room environment and away from sources of frequent mechanical disturbance.

Usage recommendations

For reliable detection, follow the installation recommendation to mount the unit low on the wall and avoid enclosing it inside cabinets or behind obstructions. Test the detector after installation and periodically verify sensor and supply status using the device's self-diagnostic indicators. Integrate the DG-1 TCM with an alarm control panel if centralised monitoring is required; otherwise, use the built-in LED and buzzer for local alarm signalling. Replace or service the sensor according to manufacturer maintenance intervals and local safety regulations.
