• 4 independent relay outputs (NO/NC selectable)
  

   

Ideal For RF433 Wireless

• Door & window magnetic contacts
• PIR motion sensors
• Gas & smoke detectors
• Vibration & shock sensors
• Wireless alarm accessories needing wired conversion
  

How it works (in one glance)

• RF433 sensor sends a wireless signal
• This receiver picks it up
• It outputs a wired trigger (one of 4 channels)
• Your alarm panel sees it as a normal wired zone
  

Why it's useful

• Add wireless sensors to a wired alarm system
• Expand zones without running cables
• Mix old and new technology easily
• Works with most RF433 sensors
• Integrate RF433 sensors into automation controllers
• Convert wireless triggers into wired inputs for relays or sirens

RealWorld Use Cases

1. Upgrading an Old Wired Alarm Panel

Many older alarm panels only accept wired zone inputs.
This device lets you add wireless RF433 sensors without replacing the whole system.

Example:
A home with an old ADT/Paradox, etc. panel wants to add wireless door contacts this receiver converts RF433 signals into wired triggers the panel understands.

2. Adding Sensors in HardtoReach Areas

Running cables is sometimes impossible or too expensive.

Example:

• A garage far from the main house
• A garden shed
• A second floor where cabling is difficult

Use wireless sensors receiver converts them to wired zones.

3. Integrating RF433 Sensors Into Automation Systems

Some automation controllers only accept wired inputs.

Example:

• Smart relay modules
• Access control systems
• DIY controllers (ESP32, Arduino, Raspberry Pi)

The receiver provides a clean wired output for each wireless sensor.

4. Expanding Zones Without Rewiring

If all wired zones on a panel are already used, this device adds more.

Example:
A business wants to add more PIR sensors but all wired inputs are full add wireless PIRs and connect them through this receiver.

5. Converting RF433 Remotes Into Wired Triggers

Some users want a wireless remote to activate a wired device.

Example:

• Arm/disarm input on a wired alarm
• Triggering a gate controller
• Activating a siren or relay

The receiver outputs a wired signal when the Single code RF remote is pressed.

6. Temporary or Portable Installations

Perfect for setups where wiring is not practical.

Example:

• Construction sites
• Temporary offices
• Rental properties
• Exhibition booths

Wireless sensors can be moved easily, and the receiver stays connected to the main system.

7. Hybrid Alarm Systems

Mix wired and wireless sensors in one system.

Example:
A home uses wired PIRs inside but wants wireless outdoor sensors this receiver bridges the two technologies.

Specifications

• Transmission Frequency: RF433 MHz
• Output Type: Wired NO/NC up to 4 Zones.
  
• Power Supply: DC 12V (Not Included)
• Application: Home security, alarm systems, automation setups
  

• This device takes wireless RF433 signals from sensors (like RF433 PIRs, door contacts, smoke detectors, etc.) and converts them into wired outputs that any traditional alarm panel can read. It lets old wired alarm panels work with modern wireless RF433 sensors.

• Relays only turns ON for 2 seconds then turns back.
