Wiring The Shps-12 - bolid ShPS-12 User Manual

− Terminals marked as "ISO Port #1" (the first separate RS-485 interface) and "ISO Port #2"
(the second separate RS-485 interface) are used for connecting to external RS-485 interface
circuits.
If necessary, the user can use the ХТ2 earthing bus to ground additional devices powered from
220V /AC. The 220V power circuits are protected by the common QF1 circuit breaker.
Upon erecting wires and cables passed through within ShPS-12, ShPS-12 mod.01, ShPS-12
mod.10, ShPS-12 mod.11 via upper cable glands, use a sealant (gasket maker) to seal inputs to provide
IP41 enclosure protection degree. For this purpose, white organosilicone one-part sealant "ВГО-1" is
advised.
2.2.3.2. Installing the Box
Installation and connection of the boxes shall be provided in accordance with design documents
developed as specified in effective regulatory documents and approved in the order as intended.
ShPS-12 can be installed on the walls and other structures of protected premises to avoid exposure
to the atmospheric precipitation and mechanical damage.
Mount the eye brackets on the box using fasteners from the mounting kit provided. Attach the
ShPS-12 on the wall at an easily accessible location. Overall and mounting dimensions can be found in
Appendix E.

2.2.4 Wiring the ShPS-12

WARNING!
When connecting external 220 V mains supply voltage to the XT1 terminal block,
care must be taken to observe the correct connection of the Line and Neutral wires.
Make the connections in accordance with Appendix A. The connection diagram is
also located on the inner side of the ShPS-12 door
Install the batteries.
In accordance with the wiring diagram (Appendix A):
a) Set the circuit breakers QF1 and QF2 to the OFF position;
b) Ground the ShPS-12 by coupling the ХТ1.3:2 "
with the ground circuit;
c) Connect the interface bus and wires to be connected to devices positioned within the box to the
relevant box terminals;
d) Connect power wires to the ShPS-12 inlet terminal (L line shall be connected to ХТ1.1:2, see
Appendix A);
e) Mount batteries and connect them to terminals observing the polarity (the red wire shall be
connected to the "+" lead of the battery, while the blue wire shall be connected to
the " - " lead of the battery).
Connect О-shape terminal of thermal sensor to the battery lead as shown in
Figure 1, according to Appendix A.
f) Turn on the QF1 and QF2 circuit breakers.
Note: Rated load current is 3 A. The power supply may operate a short period
under 3.5A (see 1.2.5) in case of activation of sound alarm devices, fire-fighting
systems, actuating devices, etc.
Warning! In case of long operation at overload, the battery charging process is terminated,
and the battery starts discharging even if the mains voltage is available. If the total load current
exceeds 4A, the power supply unit turns OFF output voltage and the equipment is left without
the power.
Recommended cross sections of wires connected to the ShPS-12 box are as follows:
o To 220V mains power (to ХТ1 terminal): 1.5 to 2.5 mm
for solid wires;
o To RS-485 line (the BK-12 unit): 0.12 to 2 mm
solid wires;
o To connect loads (the BK-12 unit): 0.5 to 2 mm
wires with taking into account voltage drops at maximum load current (minimal permitted voltage
when loaded).
When installation is completed, run the test of system operations in the Fire Alarm condition during
one hour to check whether the ShPS-12 is capable to provide functionality of the installed equipment
