Hopefully, you will never need it, but in case of emergency it will save not only your belongings, but also life. A pot which stands on the stove too long or a forgotten iron…first there will arise smoke, then it will cause a fire. The HEIMAN Smart Smoke Sensor owns an accurate capture of smoke and you will alert acousticly and visually. In a serious situation the smoke sensor alerts with a red LED which flashes rapidly and with a noisy alarm. Furthermore there is the opportunity to receive a warning on your smartphone if you are not at home. This prevents a fire emerging from smoke and expensive consequential damages.Because of the use of the wireless technology Z-Wave the sensor can be connected to any Z-Wave gateway. Thanks to the latest Z-Wave Plus standard the Smoke Sensor ensures a batterie lifetime of 3 years. Features:Detects smoke and visible particles which arise by a smoldering fireSoundlevel of alarm: 85 dB/3mLow battery indicationPower supply: 1x CR123A lithium batteryBattery lifetime: 3 yearsWireless technology: Z-Wave PlusSmoke Sensor applies DIN EN14604

Heiman WS2GW-R is a compact (80 × 80 × 26.5 mm) Wi‑Fi smart gateway for Tuya ecosystems. It bridges 2.4 GHz Wi‑Fi with 433/868 MHz sensors—supporting up to 40 devices (smoke, gas, motion, temperature, leak, door/window). Receive real‑time alerts via the TUYA Smart app, monitor LED status indicators (network, power, device), and create automation scenes. Rated –10 °C to +55 °C, ≤ 95 % RH for reliable home security.

The Heiman HM1RC-W is a compact wireless remote that gives you quick, intuitive control over an interlinked alarm network. Using RF868/RF433 communication it works with smoke, heat, gas and other compatible sensors, letting you test devices, pinpoint which sensor triggered an alert, and silence nuisance alarms with a single press. Its simple button layout and ergonomic shape make everyday operation easy for all household members. The remote is ideal for homes, offices and larger properties where many sensors are installed — it speeds up response, reduces panic during false alarms and helps keep your system reliably maintained.

The Heiman HM-5HW is a wireless interlinked heat detector that warns of sudden temperature rises with a loud 85 dB alarm audible up to about 3 metres. It monitors ambient temperature across a wide range (−10°C to +50°C) and triggers when temperatures rapidly climb into the 54–65°C window, making it especially useful where smoke detectors are less effective. The unit can link with up to 40 other compatible alarms so a single event notifies the whole system. Durable ABS housing resists moisture and corrosion. Installation is simple (no hardwiring) and the alarm can be silenced remotely. Supplied: heat sensor, screws, plugs and user manual.
