A unique XL Wireless Alarm System C, which includes a compact 4-channel Receiver (with built in 100 decibel siren), Wireless PIR & Wireless Magnetic Door & Window Contact.

This Alarm can be used on its own as a small Wireless Alarm System (protecting a small building) or as a base to build a bigger and more complex Intruder Alarm System (using the large selection of available accessories).


Battery powered Internal Wireless PIR's (passive infra-red detectors) will detect a person from up to 13 metres away and transmit a wireless signal back to the XL Wireless Alarm Control Panel up to 80 metres away. The PIR's are supplied with a simple adjustable wall bracket and are best installed into a corner of a room, ideally visible from an outside window (acts as a visual deterrent).

Magnetic Contacts:

Wireless Magnetic Contact's are used to protect vulnerable Doors & Windows, the battery powered sensors would be attached the the Door/Window & Frame (using double sided tape supplied). When the Door or Window is opened, a signal will be transmitted back the XL Alarm Receiver.  


Up to 16 Wireless Alarm Detectors can be used with an XL Wireless Alarm Receiver, they can be used to create both a full alarm condition or simple audible alert (depending on the chosen mode of operation).

The compact 4-channel Receiver has a multitude of unique features (listed below) making it a very versatile Alarm System:

  • Built in 100 Decibel Siren (channels 1, 2 & 3). 
  • Siren Duration: 3 minutes or before if turned off by a key-holder (the receiver remains armed if the siren switches off due to the 3 minute duration).
  • Built in Audible Chime (channels 1, 2 & 3).
  • Built in Audible 'Beep' (channels 1, 2, 3 & 4).
  • Built in Keypad (for arming and disarming the alarm).
  • 3 x Alarm & Alert Channels (channels 1, 2 & 3).
  • 1 x Alert Only Channel (channel 4).
  • Each Channel can work with 4 x Wireless Detectors.
  • Plugs into a 13-amp Wall Socket.
  • Battery Back-Up.
  • Option to Turn a Any Channel OFF.
  • Built in Wireless Transmitter (for activating wireless sirens & auto-dialers).
  • Can also be Armed & Disarmed using Remote Control & Wireless Keypads (4 in total).
  • Low Battery Warning.
  • Visual LED Notification.
  • Home Arm Option: (instant activation of the siren).
  • Away Arm Option: (45 audible second count down upon activation).
Mounting the PIR Sensor:
The key to successful operation of any PIR sensor is choosing the correct location. A sensor mounted in a unsuitable location has the potential to cause false triggers and reduce performance. The main rules that should be followed are:
  1. Mount the PIR into a corner of a room, if possible visible from an outside window (this also creates a visual deterrent to a potential thief).
  2. Avoid heat spots from bright lamps suddenly turning on or off.
  3. Do not install immediately above a radiator.
  4. Do not install in a glass roof conservatory.
Mounting the Magnetic Contact:
  1.  Attach the battery powered magnetic contact to the top edge of the door or window (towards the hinge end) using the double side tape supplied.
  2. Using the double sided tape supplied, attach the magnet onto the door or window frame, so that when closed it is nearly touching the magnetic contact.
  3. Put the XL Wireless Receiver into chime mode, open the window to test the positioning of the Magnetic Contact & Magnet, if the receiver chimes each time the window is opened then the positioning is correct.
  4. Once you are happy with the positioning, finish the installation by fitting two screws (supplied) through the two holes in the magnet, into the door or window frame.
  5. Please Note: the positioning of the Magnetic Conacts can vary on some doors or windows.

  • Receiver Located Inside House, Wireless PIR located outside on the Drive or Car Parking Area (set to alert channel 4) & the Wireless Magnetic Contact fitted onto the Front Door (set to alarm & chime zone 1), when the PIR detects someone outside the Receiver will beep, if the door is opened the Receiver will either chime or go into full alarm mode (depending on what mode of operation the Receiver has been put into).
  • Receiver, PIR & Magnetic Contact fitted into the house, if the Alarm is Home Armed, the Magnetic Contact will be  'ON' protecting the door, but the PIR will be 'OFF' (allowing you to walk around the house. When the Alarm is Away Armed, both the Magnetic Contact & PIR will be 'ON'.
  • Receiver Located Inside the House, Wireless PIR & Magnetic Contact fitted into a external building (shed or garage), up to 60 metres away. The Receiver can be set to either Chime or Full Alarm modes for different times of the day.
  • This system used as a base kit, to build a far more comprehensive alarm system, adding additional Wireless PIR's, Magnetic Contacts, Vibration Sensors, Sirens, Tilt Switches, Remote Controls, Auto-Dialers etc.
