TaBle 1
*N:
in this condition (EPs quantity), the
riser system power supply cannot
provide current to this kind of
handset, an additional power supply
must be used.
The information of table is 5 based on
below condition
1. 50 m cable from Floor shunt
to handset and 5m cable
between floors.
2. 0.5 m cable between Floor shunt
and Floor shunt in same floor for
the projects with more than one
floor shunt on each floor.
3. Between Power supply and 1st
Floor shunt or riser shunt, for the
connection use 2 wire cables.
4. Type of door lock release for EP
is DC12 V/1 A., release time 100
ms or less. The door lock does not
need power during.
*1:
2 small EP and 1 EP can work at the
same time with handsets connected
to the same power supply.
*2:
1 small EP and 1 EP can work at the
same time with handsets connected
to the same power supply.
5. When using an entrance panel
video mixer in the riser (more than
one EP in the riser), the distance
between entrance panel video
mixer and riser shunt is 0.5 m.
6. The data listed in above table
are the requirements based on 4
apartments per floor.
For example: if riser use type of
handset, and there is only one EP
without a/C, then we could found
that this system power supply can
afford other 40 handsets except
EP and riser shunt according
to above table. But these 40
handsets need to be arranged as
4 apartments per floor.
If the height of each floor is 5 m,
the height limit should be applied
at the same time, which means
(40/4- 1)*5= 45 m.
7. If the riser EP get power from
an auxiliary power supply, the
riser system power supply only
provide power to riser shunt, the
floor shunt and the handsets.
