An active Infrared beam device to give warning of the arrival of a visitor on your property, and which can also be used to trigger a warning siren or floodlights for your own convenience.
The Infrared beam consists of a sender and a receiver, which are mounted on either side of the drive. Both are normally connected to the Control box, which provides 12V power for the system, and contains a buzzer and timing circuits for external functions. It is plugged into the 240V mains in the house.
Sutcliffe Electronics do not produce a reflector model with sender and receiver, on one side of the drive, and a target on the other, since they are much more prone to false alarms, and can be easily bypassed.
The Control box has an integral 13A plug pins, and contains an adjustable period Buzzer, a Delay timer, and an ON timer with a 10A relay. It can support 2 separate beams. Each beam comes with 100M of cable (Recommended Maximum Cable 500M.) and 2 mounting brackets. One knob is used to adjust the On time of the buzzer, (1 second - 3 minutes), and a further Two knobs adjust the relay Delay and On time. By this means any external function is delayed, to prevent the beam position from being marked by a prospective intruder. Similarly the boxes are best mounted IN rather than ON mounting posts, in order to hide their position.
No special tools are required to set up the beam, which is aided by a red indicator which shows when the beam is absent or broken. It can be fitted by a competent handy person with the instructions supplied.
1) 10M, 20M, or 40M Continuous beam units
( Maximum distance between sender and receiver )
2) Separate power supply module for sender, for where it is more convenient to run the sender from another place.
3) Extra Function Timer Modules ( See separate sheet )
4) Changeover photocell unit, making it possible to have different external functions day and night. Used in conjunction with (3) above.
5) Special 12V system, for where mains is not available, or it is a requirement that the system runs off an alarm panel.
6) Extra cable in 100M rolls
7) Extra buzzers.
8) Sirens to provide external warning.
9) Systems are manufactured to order, and can be modified to suit. Please ring to discuss your requirements
1) Infra red active beam ( not passive IR. ). Consisting of separate receivers and senders, in pairs.
2) Weatherproof, designed for external use.
3) Relay switch, with isolated contacts for external functions.
4) Integral warning buzzer in control box, with knob to adjust time. Plus provision to power 2 extra buzzers.
5) Runs 24 hours a day.
6) Heating components to reduce condensation.
7) Units run at a nominal 12V. No danger if cable is damaged
8) Two complete beams, or four receivers only, can be fitted to one control box.
9) 500 metres of cable can be used with each beam
( Maximum loop resistance 60 ohms ).
10) Both ends of the beam need power.
11) Integral delay timer for external alarms etc. The delay prevents the beam position being noted. For instance a 30 second delay followed by a 10 second blast on a siren.
12) Buzzer and Siren reset automatically.
13) Stainless steel mounting brackets.
14) Can be used as part of a larger system.
15) Easy to fit by the competent DIY person
16) A preventative deterrent as well as an automatic door bell for the drive.
