connection, the distance between individual detectors must be a maximum of 30 m. The
wireless range can be negatively influenced by the structural surroundings.
The detectors can be cascaded, meaning that the detectors are not connected in one
direction only, so the alarm signal can be transmitted from the first to the last in a chain.
This means that when a detector receives an alarm signal, it forwards the signal on to the
detectors it is connected to.
Note: To assemble according to VdS, the delay from the triggering sensor to the last
connected sensor must not take more than 30 seconds. For correct assembly, make
absolutely sure that this requirement is adhered to.
