Sealing of the threaded connection can be carried out with epoxy compounds or similar
materials with the operating temperature and properties compliant with the operating conditions of
the call point.
8.15.
In order to connect the call point to the alarm circuit, open the cover (6).
Connection of the call point when the power supply is on is prohibited.
8.16.
Insert prepared cables into the respective cable glands (ends of outer cable sheath must be
projecting by minimum 5 mm from the input device inside the call point), tighten the unions of the
cable glands and fix them with lock nuts.
8.17.
Check the cable clamp in the cable glands for pulling out.
8.18.
The electric cables connected to the call point should be protected from tension and
torsion loads.
8.19.
The call point must be connected to the alarm loop in accordance with the diagrams
shown in Annex B observing the legend to the images.
Power supply and data exchange of the call point are provided via the four-wire communication
line: 2 wires - RS-485 line, Modbus RTU protocol, 2 wires - electrical power supply. The call
points must be connected to communication line in parallel, with strict observation of polarity.
When connecting the call point to FACP via R1 relay ‘Activated’ and R2 relay ‘Fault’, an
additional R
ADD
and terminal R
TERM
resistors are to be selected in accordance with the FACP
documentation.
8.20.
For connecting the wires to the terminals:
a)
remove 6-8 mm of insulation from loose wires of all cables
b)
open the input orifice of the terminal using the supplied WAGO terminal key or an eyeglass
screwdriver
c)
insert the wire without insulation into the terminal entrance hole and clamp by releasing the
terminal wrench or the screwdriver
d)
after that, self-disconnecting becomes impossible.
8.21.
Check the completed installation by drawing attention to the correctness of the
connections, the presence of all fastening and locking elements and their correct installation.
8.22.
Close the cover (6) of the call point, tighten it until properly sealed, use the driving
element (2) to prevent self-unscrewing. The minimum tightening torque of the call point cover must
be 16 Nm. The correct position of the cover is shown in Figure 1.
8.23.
Install the seal via the holes in the cover (6) and the driving element (2) itself.
8.24.
Each call point must be grounded by means of the external earthing bolt (21) (Figure 1).
When connecting the earthing, please, follow the requirements of the Electrical Installation Code.
Apply corresponding grease on the contact grounding clamp for protection against corrosion and
atmospheric agents.
8.25.
When the fire alarm system installation is complete, check functionality of data exchange
between the call point and the top level device by reading the corresponding registers of the call
point status.
8.26.
When the call point (device) is in stand-by mode, the green LED is in flashing mode. For
activation of the call point, break the seal and pull out the driving element (2) (for the IP535-07ea-
RS-B or UDP IP535-07ea-RS-START, shift the protective element (8) thus breaking the removable
element (3) and giving access to the driving element (2), then pull out the driving element). The
device will receive ‘Activated’ signal from the call point. Upon acknowledgement of the activation
signal by the panel (handshake), the switch of the call point (device) from standby mode to
‘Activated’ mode will be indicated by means of the red signal LED on the face surface of the cover.
Fixation of the driving element of the call point IP535-07ea-RS-A is carried out by means of a
braided rope (30).
The method of returning the call point from ‘Activated’ mode back to standby mode will
depend on the value of bit 0 ‘Activation registration’ in register 50 (see Annex B).
