Installation instructions
7.1
Wall mounting
1. Pull the wires through the wire entry and ensure they do not get in way of operations.
2. Prepare the wall for the four 8mm anchor screws (stop screws) which must be positioned in
correspondence with the holes on the backplate of the metal enclosure (paragraph 5.1 - [J]).
Danger:
Care must be taken not to drill in the vicinity of electrical wiring, heating ducts and
plumbing.
Note:
Choose anchor screws which are capable of supporting 20kg and which are suitable for the
characteristics of the wall.
Ask for professional advice with regard to the best type of anchor screw for the wall concerned.
3. Using the 4 anchor screws, attach the enclosure securely to the wall.
7.2
RS485 BUS wiring
Figure 11 - Connecting the RS485 BUS
1. Use a 4 pole shielded-twisted cable.
2. The cable length between the INIM panel and the SmartLevel power supply station must not exceed
1000m.
3. Connect one end of the cable shield to the control panel earth terminal.
Note:
The terminals of the SmartLevel power-supply module are isolated electrically from the RS485 BUS of
the fire-detection panel.
In order to allow the fire-detection panel to distinguish between the various SmartLevel power-supply units
on the RS485 BUS, you must assign a different address to each. When assigning addresses refer to
paragraph 10.1.3 Addressing the power supply station on the RS485 BUS.
The end-of-line jumper (JP3) should be in the EOL position only when the power supply station is the last
device on the RS485 BUS.
