5. INSTALLATION
A = Check earth connection existence;
B = Control earth connection efficiency;
C = Assure the mains supply voltage quality, in order to avoid excess voltage which could occur in the case the control unit
were occasionally powered by a generating set;
D = Provide for the connection of devices outwardly the control unit for suppressing electrical interference (for example
FAR module);
E = If mains current instability occurs, provide for the connection of a saturated iron stabilizer;
F = Check the existence of a magnetothermal switch or arrange an adequate one, for protection against the mere over-
loading of the electrical system. In fact, although the additional use of a differential switch (cut-out switch) is provided by
law, in order to avoid the electrocution of individuals, valuations regarding both individuals safety (the equipment below the
switch is under low voltage) and the need to guarantee the surveillance system continuity, suggest the sole use of magne-
tothermal switch in order to guarantee the mains supply continuity;
G = In case of use of built-in telephone communicator, provided for the installation of a telephone interference suppression
filter mod. PTN;
This filter must be installed in close proximity instead of the telephone line fuse box ; this does not permit the tele-
phone line wires entering and exiting the dialler to be contained in the same duct since the interference on the entering
wire is filtered by the PTN module.
If PTN module is installed near the control unit’s housing, it is necessary to separate the entering and exiting telephone
line wires in two separate ducts, so as to avoid problems of mutual induction which may occur on the wires upstream the
PTN module.
H = Evaluate the configuration of the electrical connections of the various accessories (sensors, keyboards, sirens ...) for
the control unit’s optimal positioning;
I = The control unit must be wall-mounted, in a suitable position to permit the access of wires for electricity mains supply
and telephone line, the system alarms wiring, the eventual connection of a printer and lastly subsequent maintenance
activities on the control unit itself.
THE WALL MUST BE ABLE TO SUPPORT THE CONTROL UNIT WEIGHT.
ET8/480, ET8/480S and ET8/480PT models of control unit are compliant with CEI 79-2 standard is the level of
performance declared. They resulted immune to radio-frequency and voltage pulses to the mains supply terminals;
tests have been carried out according to IEC 801-2-3-4. They are also compliant with the 89/336/EEC directive relative
to electromagnetic compatibility and the 93/68/EEC directive relative to low voltage safety.
The telephone section provided with TLC 049407/00 Test Report dated 06/07/2000 issued by the Ministry of
Communications Accredited Laboratory No. 58.
The following programmaings degrade the performance level from 2nd to 1st:
- Inputs programming as NC and/or TR9000 and CT8/TR transponders.
The following functions and devices are not IMQ - SISTEMI DI SICUREZZA certified:
- Fire alarms management, command devices and inputs tamper disabling, self-disabling function relative to inputs in
anomaly conditions when exit time ends
- Printer mod. CP8/PRINT, transponder mod. CP8/TRS, Teleservice, WINASSIST software, modem mod CP8/MDE,
browser light WABL0034/CD, the use of TR9000 and TR9000S transponders, FAR and PTN filters.
ATTENTION:
Ensure that electrical system is equipped with an efficient earth connection. The control unit includes a
telephone communicator which integrity depends on the earth system efficiency; in any case it is rec-
comended the use of appropriate auxiliary protection devices which should be connected outside the
metallic housings, such as FAR model for protection on the electric network and the PTN model for protec-
tion on the telephone system. Before proceeding with the installation, it is reccomanded to consult the
CEI 79-3 standard concerning the installation of security systems, the CEI 64-8 standard concerning the
installation of low-tension systems. Operate professionaly.
