Can I Use More Than One Repeater on a Wireless Alarm System?
You can technically use more than one repeater on a wireless alarm system, but it is usually not beneficial. You cannot repeat a alarm signal more than once. You would only use multiple repeaters if you had sensors in multiple directions or if you were using multiple wireless frequencies.
Wireless sensors communicate with security systems by sending out wireless signals. These signals can only travel a certain distance, and the sensor will not work properly if the signals cannot reach the panel. Each wireless sensor normally has a listed maximum range, but the signal range can be reduced due to obstacles like walls and large metal objects.
The easiest way to extend the range for a wireless sensor is to use a wireless repeater. A wireless repeater will take the signal sent out from a wireless sensor and send it out a second time. This will effectively double the sensor's range. So if a sensor only had a maximum range of 200 feet in open air, a wireless repeater would theoretically increase this max range to 400 feet.
When using a repeater, it must be able to accept and send signals that are compatible with the wireless sensors and the alarm panel. A wireless sensor will send signals at a particular frequency, and the panel must have a wireless receiver that accepts that frequency. Likewise, the wireless repeater must also accept that particular frequency for the transmission to be successful.
A big factor to consider with repeaters is that you cannot repeat a signal more than once. In other words, you can't have a signal travel from a sensor to a repeater and then to another repeater. The signal must reach the ultimate destination, the wireless receiver, after being sent out again by a wireless repeater.
Having said that, there are some rare situations where you might use wireless repeaters. If you have sensors in different directions from the panel, then you might use multiple wireless repeaters to repeat signals from varying directions. Meanwhile, the wireless receiver would be in the center of the setup.
You might also use multiple wireless repeaters if you have wireless sensors that operate at different wireless frequencies from one another. Remember, each wireless repeater can only accept one particular wireless frequency. If you have a system where multiple wireless frequencies are being used, you will need multiple wireless repeaters if you want to repeat the signals for every programmed sensor.
An example of a situation where you might be using multiple wireless frequencies on the same security system is if you have an IQ Panel 2 Plus. These panels include a 915 MHz wireless receiver for supporting PowerG Sensors, as well as a legacy wireless receiver. There are three legacy wireless receiver options available, which are 319.5 MHz, 345 MHz and 433 MHz.
An owner of an IQ Panel 2 Plus might use wireless PowerG Sensors and wireless legacy sensors at a different frequency all on the same alarm system. However, they will need two separate wireless receivers if they want to repeat all their signals. One wireless receiver will repeat the PowerG signals, while the other wireless receiver will repeat the legacy sensor signals.
