The Dinsafer Helio DRCH1 is a compact keychain-style remote controller designed as an accessory for the Dinsafer Helio series smart alarm system. It provides four dedicated functions — arm, disarm, home arm, and SOS trigger — accessible from up to 180 m away in an unobstructed line of sight, making it practical for arming the system while still outside or disarming before entering.

The controller is powered by a single CR2032 button cell and is designed for low standby current (≤10 μA) to extend battery life. The working voltage is DC 3 V and the transmission frequency is 433.92 MHz.

Key Features

• Four dedicated functions: arm, disarm, home arm, SOS trigger
• Transmission frequency: 433.92 MHz
• Transmission distance: up to 180 m without obstacle
• Working voltage: DC 3 V
• Battery: 1 × CR2032 button cell (3 V)
• Working current: ≤35 mA
• Standby current: ≤10 μA
• Working temperature: -10°C to 50°C
• Humidity: ≤90% rh (non-condensing)

Product Benefits

• A single-device controller covering all four arming states eliminates the need to access the main panel for routine arm/disarm operations
• The 180 m open-air range allows the system to be armed from a driveway or parking area before entering the building
• The ≤10 μA standby current ensures long battery life from the CR2032 cell without frequent battery changes
• The compact 74.4 × 34.5 × 16.1 mm form factor and 18 g weight (without battery) are practical for daily keychain carry
