The antenna must not be installed in parallel to low-voltage electrical wires, or it can affect
performance of the antenna.
1.3 Connecting the alarm control panel
Connect the control panel telephone communicator to the TIP and RING terminals.
1.4 Connecting the devices to the inputs and outputs
1. Connect the devices whose operation is to be monitored by the module to the input
terminals.
2. If the module is to monitor the presence of AC voltage fed into the device from which the
module is supplied, the wire from the secondary winding of transformer from which that
device is supplied is to be connected to the AC input terminal (see Fig. 2).
3. Connect the devices which are to be controlled by the module to the terminals of outputs.
Fig. 2. Example of connecting supply and monitoring AC voltage presence.
1.5 Connecting the digital temperature sensors (1-Wire)
You can connect up to 8 digital temperature sensors to the 1-Wire bus. The length of wires
should not exceed 30 meters. If several sensors are to be connected to the bus, it is
recommended that you use the distribution box module (MZ-2 or MZ-3).
SATEL's product offering includes the
DS-T1
waterproof temperature sensors. They make it
possible to measure temperatures ranging from -35°C to 60°C. They are designed for surface
mounting indoors or outdoors. To secure them to the mounting surface, you may use
adhesives or screws. The DS-T1 sensor wires are to be connected to the bus terminals in the
following manner:
black wire – terminal S1 (common ground),
green wire – terminal S2 (data),
white wire – terminal S3 (power).
