WIRELESS DOOR/BEAM ENTRY ALARM

Features

DEA7WL2 is a compact wireless entry alarm system which is easy to install indoor. It is designed for both residentialand commercial using such as garage door, shops, warehouse restaurants etc. to alert you to the entry of customers and visitors. The system consists of a send/receive unit which transmits an IR beam across the doorway onto a prismatic reflector mounted on the opposite side. The beam is reflected back to the receiver to complete the circuit. Whena person walks through the beam, the circuit is interrupted and this causes the alarm to sound an audible warning. The warning buzzer can be mounted in any suitable location.

Planning on using it outdoors?

It is not the recommended application. Installation under direct sunlight can be tricky and could result in decrease of reliability.

5-694MHZ 4G ANTENNA FILTER

The 700 MHz frequencies used by some 4G services are next to the frequencies used for FTA TV; there is a small chance this may cause disruption to FTA services. If you areexperiencing interference since your area retuned, this filter may assist in filtering out these signals.

3-IN 8-OUT MULTISWITCH

Doss SMS38F multiswitch can be used with a dual LNB to distribute satellite TV signals to multiple receivers from asingle dish and LNB. It features 3 input which means it allows you to combine a dual LNB plus an input from a terrestrial antenna.

This product saves the hassle of installing several satellite antennas for your multiple television subscribers needs.

It distributes your satellite system up to 8 output receivers.

Note:
Doss splitters will also function as combiners.

  • When combining modulated signals, leave at least a 2 channel separation i.e. Channel 21 for the first channel and Channel 24 for the next etc.
  • It is also recommended that if you also have an antenna connected to the system, you use a Digiair Pro when selecting the appropriate channels. The spectrum analyser function will display where there are the lowest levels of interference i.e. where the modulated should be placed in the radio spectrum.
