Preparing the connection cables

Preparing the cable
The cable will be brought to the detection point. Professional standards for
running wires and maintaining and protecting cables must be followed.
Disconnecting power
If the central system to which the transmitter will be connected is already
activated:
1. Block the system's alarms during the operation to avoid accidentally
triggering them.
2. Disconnect power to the detector or the corresponding line.
Opening the detector
Remove the 4-mm hexagonal cover locking screw before unscrewing the
detector's cover (Figure 2, 4).
Running the cable
Follow all instructions provided by the manufacturer of the cable
gland and be sure to properly connect the braided shield.
