Long Range Wireless Gate Alarm with Outdoor Receiver & Adjustable Siren

The Protect-800 Long Range Magnetic Gate Contact Alarm features an outdoor receiver and a weatherproof adjustable siren, ideal for gates, doors, or roller shutters. The siren offers 32 selectable tones and volume control from 0 to 106 dB. Duration can be adjusted via the receiver, from 1 second to latched ON, with multiple options in between. Using the included long-range remote control, the system can be armed, disarmed, or triggered remotely from up to 800 metres. The SOS button allows immediate activation for security, medical, or visibility purposes.

How It Works:

• The battery-powered transmitter board is housed in a weatherproof box and communicates with the outdoor receiver over 800 metres (line of sight; 400–600 metres in typical conditions).

• The transmitter uses a 3 V CR123A battery (supplied) lasting 12–18 months.

• The wired contact, protected by an armoured sleeve, attaches to the gate post, door frame, or floor. The magnet mounts to the gate, door, or shutter, with an optional right-hand bracket included.

• When armed, opening the gate triggers the siren for the selected duration, which can be canceled via remote control.

• The SOS function latches the siren ON until manually switched off.

Outdoor Receiver:

• Fully weatherproof, powered via a 12 V plug-in transformer

• Two channels, each supporting up to four Protect-800 sensors, including PIRs, vehicle probes, transmitters, gate contacts, and bird box PIRs

• Supports additional 12 V devices with independent duration settings per channel (e.g., siren for 20 s, floodlight for 10 min)

Remote Control Features:

• Arm/disarm each channel

• SOS trigger for connected accessories (siren, buzzer, floodlight, or any 12 V device)

• Latches devices ON until turned off via remote

• Feedback LED confirms successful signal

• Multiple remotes can be paired with unlimited range

• Powered by 2 × AAA batteries

• Operational distance: 800 metres line-of-sight (400–600 metres typical)

Indoor Receivers:
Optional indoor chime receivers can notify occupants regardless of the outdoor receiver status.
