4G 2B Beam Perimeter Alarms

How it Works:

The four sets of 2B Solar Beams would be mounted on suitable Posts, Walls or Fence Posts and positioned to monitor and protect vulnerable locations which can be as wide as 100 metres.

The Wireless Receiver & 4G Dialler are fitted neatly inside the weatherproof mounting box which would be located inside a building (with a power supply) up to 400 - 500 metres away (this can be expanded).

The Alarm would normally be Armed & Disarmed using the Remote Controls (supplied) or by sending a Text Message (this can also be done by using the built in keypad on the 4G Dialler although we would recommend the mounting box is hidden away if possible).

Arming & Disarming 4G Dialler

The Loud Wireless Siren is powered by a plug in 12v DC transformer and would normally be fitted onto the building where the mounting box is fitted (outside or inside). 

If the Beams detect a Person or Vehicle whilst the Alarm is Armed, the system will contact up to 9 key-holders by Phone or Text (or both) together with triggering the Loud Siren & Flashing Strobe (the built in Siren on the 4G Auto-Dialler can also be used). 

This Perimeter Alarm System can be expanded in many ways (please Contact Us for Advice).

More Details listed below:

Wireless Beams: 

These impressive Solar Powered 2B Wireless Perimeter Beams (often called laser beams) are packed with impressive features listed below: 
  • Battery Powered with Built in Solar Charging: (making for easy installation).
  • 2 pairs of Invisible Detection Beams.
  • Dual Detection Technology: (prevents false alarms from small animals and moving debris).
  • Up to 100 metre Detection: (can be less).
  • Impressive 900 metre Wireless Range (can be expanded): 
  • Quality Build.
  • Supplied with Wall & Pole Mounting Brackets.
  • Test Lights: (for easy installation).
  • Top up charging Ports (allows the Beams to receive an occasional maintenance charge if required). 

2B Perimeter Alarm Beams

The Dual Detection Technology works by having a pair of Detectors (set 60 mm apart from each other) both Detectors have to be breached simultaneously to create an activation which allows small animals, insects, leaves & debris to safely pass by.

Dual Technology Beams

These 2B Beams have two sets of the Dual Detection Sensors (whilst the 1B Beams only have a single pair), this makes it far harder to try to go under or over the Detection Beams if trying to avoid detection.

1B and 2B Beams 

The Beams also have an additional Charging Port which can be used to give the Beams a boost charge should you experience a lengthy duration of low sun light, or perhaps one of the beams needs to be fitted into a slightly shady location.

They are very easy to install and have a digital display to help line them up with each other.

The 2B Beams also have an optional built in buzzer, which can be popular in some applications (such as safety applications or where an additional audible alert is required).

The buzzer can be chosen by pressing the set up button 3 to 6 times on the back of the Beams, or turned OFF by pressing the same button 7 or 8 times).

Operating Range:
The Wireless operating range between the Beams & Receivers is 900 metres (line of sight) which can be doubled by using the signal repeater (part number 004-2910).

Receiver:

The Wireless 4 - Channel Wireless Receiver is mounted neatly inside the weatherproof box which is powered by a standard Plug in Transformer and can operate up to 128 Wireless Beams, PIR's, Gate & Door Sensors (so can be expanded at any time).

4 Channel Wireless Receiver

The Wireless operational range between this Receiver & the 4 sets of 2B Beams supplied is an impressive 900 metres (which can be more than doubled by adding one to four signal repeaters if required).

4G KP9 Auto-Dialler:

4G KP9 Dialler

The 4G Auto-Dialler supplied and mounted inside the weatherproof box with this Perimeter Alarm will contact key-holders by Phone & Text if triggered, it is packed full of features including:

  • Operates on 4G, 3G & 2G Networks.
  • 95 x Wireless Zones (allowing other sensors to be added to the alarm system).
  • Contacts up to 9 x Key-holders by Telephone & Text Message (optional).
  • Built in Internal Siren (adjustable duration from 0 to 999 seconds).

  • GSM: 900/1800 (2G, 3G & 4G Networks).

Communication:

When the KP9 GSM Panel calls key-holders by Telephone, the key-holders have the option to:

  • Press * on their Telephone (this will stop the alarm calling other key-holders but remain fully armed.
  • Press # on their Telephone (this will stop the alarm calling other key-holders but will disarm the panel.

SIM Card:

We do offer two Roaming SIM Cards from a third party supplier (at cost) designed for use in this Alarm System, these are low level contract sim cards (working on a direct debit) operating over all the major UK Networks ensuring your Alarm has the best signal available in all locations. 

The two options are our 20 Plan (click here) & 50 Plan (click here), please click the links to read all about them.

You can also purchase the product with no sim card and simply use your preferred supplier (many options are available).

Weatherproof Mounting Box:

The weatherproof box has a built in UPS which is designed to operate the Alarm through Power Cuts and has a Tamper Switch on the lid for additional Security.

It also allows the Receiver & Dialler to be neatly fitted inside together with adding protection against any damp that could be present in a typical building it may be used in (workshops, farm buildings, garages etc).

We do recommend fitting the box in a out of sight position as it can be Armed & Disarmed using the two Remote Controls supplied (more can be added). 

Weatherproof Box

Wireless Siren:

The Wireless Siren & Strobe has an impressive 120 Decibel Siren, Flashing LED (in standby) Bright Strobe (in activation), Back up Battery, Tamper Buttons together with a 100 metre (line of sight) working range from the 4G Auto-Dialler.

KP9 H/D Wireless Siren

The Siren is powered by a standard Plug in 12v Transformer but is activated Wirelessly from the 4G Dialler (so no cable needs to be connected between the two).

The Siren also has a slow Flashing LED when it is in the disarmed mode which makes for an Ideal Deterrent.

The Siren would only be active when the Auto-Dialler has been Armed, which allows you to have a simple Chime facility from inside the mounting box during chosen times.

You can add multiple additional accessories (up to 128 detectors) to this Perimeter Alarm system to suit most applications, the options include:

  • Additional Solar Beams (3 sizes available).
  • Outdoor or Indoor PIR's.
  • Window & Gate Contacts.
  • Smoke Detectors.
  • Additional Sirens or Buzzers (wired & wireless).
  • Speech Alerts.
  • Relays (for lighting).
  • Flashing Strobes.
