Installation rules for video door entry systems
Do not route the riser wires in proximity to power supply cables
(230/400V).
In the branches to each user, insert terminal Art. 1214/2C supplied
with the bracket Art. 5714C and 4784 and interphones Art. 2628
and Art. 2638 on the riser. Terminate each riser or branch with Art.
1216 supplied with Mixer/power supply Art. 4888C and video
module Art. 4660C.
Depending on the cable used for the riser, set the closure on
Art. 1216 as shown in the table below.
According to the cable used for the riser, assess the maximum
distance which can be reached between Mixer-Power supply
Art. 4888C and the monitor furthest away, and between branch
terminal Art. 1214/2C and the monitor furthest away. According to
the connection cable used, determine the maximum distance
between the
external video unit and mixer/power supply Art. 4888C.
Each Art. 4888C can handle a
MAXIMUM of 4 riser branches, see
variant SB2/BGC on page 103.
For systems with main and secondary doors, use line
concentrator Art. 4834/9 and switcher Art. 1224A.
For a single door, it is possible to connect
up to 9 mixer/power
supplies Art. 4888C after Art. 4834/9 (see diagram
SB2V/EN/115GC, SB2V/EN/112GC on page 96).
Each Art. 4834/9 can handle a
MAXIMUM of 9 branches: if more
branches are required (up to 16), install two concentrators Art.
4834/9 in series.
Art. 4834/9 must be preceded by the respective video signal
amplifier Art. 4833C (see variant SB2/CC on page 105).
You can fit a
MAXIMUM of 2 concentrators Art. 4834/9 in series .
The MAX number of users that can be connected to a single
Mixer/power supply Art. 4888C is 100
regardless of whether they
are on a single riser or distributed over several riser branches (e.g.:
100 users over a single riser or 25 users over each of the 4 riser
branches).
It is possible connect
up to 25 monitors in series for each riser
branch (see variant SB2/GGC on page 104); in this case, to
determine the
MAX distance between external unit and the last
monitor in the series, see column A in the table one page 84.
The connection between several monitors with the same user code
(MAX 3) can be made in series or as a branch from the riser.
Interphones Art. 2628 or 2638 with the same monitor user code
must be branched directly from the riser by means of Art. 1214/2C.
Art. 4888C powers
only one monitor for each call, so for systems
with several monitors with the same user code, the additional
monitors must be set as secondary; power each additional monitor
separately with Art. 1212/B, according to the configuration you want
to create.
The cameras of external units must not be aimed at sources of
direct light (e.g. lamps, sunlight, reflective surfaces, etc.).
