Application
The storey call button accessory
ZERT 811-... can only be used in the
HTS 811-... . It is used to convert an
existing door bell and door release
system with storey call button / an
existing intercom system into a
1+n system.
The storey call volume of telephones
with a mounted ZERT 811-... is
approx. 6 dB less than that for the
2+n side circuit installation. The
range between the entryway
speaker and the telephone is
reduced to a maximum of
200 metres with a core diameter of
0.8 mm and it is not possible to
connect a further HT in parallel.
Control functions are inactive during
storey calls.
Electrical voltage
Mounting, installation and
servicing work on electrical
devices may only be performed
by a suitably qualified electrician.
Electrostatic charging
As a result of electrostatic charging,
direct contact with the circuit board
can result in destruction of the
device.
Discharge your body on a metal
earthed object before inserting the
circuit board in the device. The
circuit board may only be inserted
when the device is not live.
Scope of supply
ZERT 811-... comprising:
• Circuit board with pre-assembled
terminal cores
• Double-sided adhesive tape
• This product information
Q
Range
The loop resistance (line and return
line between entryway speaker and
the most distant in-house telephone
with ZERT 811-...) may not exceed
16 Ohm. A core diameter of 0.8 mm
allows a range of approx. 200 m.
The loop resistance between the
entryway speaker and the line
rectifier may not exceed 8 Ohm
(100 m if 0.8 mm cable core
diameter is used).
Mounting
1 Using double-sided adhesive tape,
attach the circuit board to the base
plate of the in-house terminal
2 Connect the three cores of the
ZERT 811-... to the terminals of the
HTS 811-....

Connection of the 3 cores 1, 7
and ERT takes place at the
ZERT 811-..., not at the circuit
board of the HTS 811-...
