FAQ

The Sensor (beam) / Transmitters can be used indoors and outside. They are designed to withstand weather including rain and snow, but are not designed to be submerged in water. When installed outside the Sensor (beam) / Transmitters do best when in a covered area and not in direct sunlight.

No alarm system can claim that they have a foolproof system for ‘false’ alarms in the unstable area outside the buildings, but we all have certain measures to minimize the possibility of false triggers. In Drongo Voice Alert’s case we have filters that you put in the lens of the sensor and the principle is that you block out the areas that you do not want. So we suggest that you 1) mount your sensors 1.5 above the ground 2) Insert the bottom part of a horizontal filter in the lens to block out small animals. 3) Adjust your lens just above your biggest ‘normal’ pet. (a Great Dane is pushing the limit for a normal pet).

A detailed answer to provide information about your business, build trust with potential clients, and help convince the visitor that you are a good fit for them.

It is possible for branches to cause a false trigger. The best location to install the Sensor (security beam) / Transmitter in an area where tree branches and bushes will not be blown by a wind in the detection zone of the Sensor (Security Beam) / Transmitters.

Normally 1-2 seconds but there is a way to make it a bit more sensitive.

The maximum distance between the Receiver Base (Control) Unit and the PIR wireless sensors (security beams) is 300m if there are no obstructions (line of sight); and approx. 100m through walls and obstructions. The distance can be increased with indoor or outdoor repeaters. The maximum effective distance for the PIR sensors (Security beams) is 0-20m although it could be a little bit further.

The Receiver has a built in backup battery, that will hopefully last for many years and will keep the system running for about 2-3 days.

The system is designed to function through the interior walls of a home and exterior walls of a home. The Sensors (Security Beams) / Transmitters have difficulty transmitting a signal through aluminum siding or metal surfaces and are best located on a window in that situation.

There is no limit to the number of Sensors (security beams) / Transmitters that can be installed with a system. There are 6 voice messages (that you record in your own voice depending on application) or areas that are available for the Sensors (security beams) / Transmitters to activate.

Yes there is two ways that can help 1) there a jumper inside the transmitter that you can set that will increase the number of signals send out to the Receiver, and 2) You can install a repeater that strengthen the signals for about 500m.

Yes. A Sensor (Beam) can be programmed to trigger recorded messages from one or more Receiver / Speakers (Base Units). For example, suppose you were a Retailer and placed 1 Sensor (Security Beam) by the front door. When the Sensor (beam) is triggered, you could use one Receiver / Speaker to play a message such as “Welcome to my store. Let us know how we can help you.” The same Sensor (motion detecter beam) triggers a second Receiver / Speaker in the back office, notifying staff someone is in the store with the message “A customer is out front.”

Yes, the Sensor (beam) / Transmitter will work in the dark or in full light.

The expectation is, with the new AAA batteries that it wil last about 18 months to 2 years depending in how busy the area is where the sensor is placed. Temperature can also affect the life of any battery. Operating a battery at cold temperature will reduce its life.
