Connection of traditional inputs XSAT HP
By SERIAL use of XSATHP satellite , the detectors connected to traditional inputs can be connected
in both "balanced zones" and "balanced zones with tamper indication" way, as the
configuration of these zones occurs via the control panel.
Using XSATHP as UNIVERSAL, the detectors connected to the traditional inputs must be necessarily
connected as "balanced zones with tamper indication".

Indication of inputs status
The indication of the inputs status, for the satellite configured as UNIVERSAL will occur with activation
of first 3 OC outputs according to the unbalancing input , or, should it be set as AVS satellite, with
serial communication of one of the first 3 physical zones of the satellite.
If these inputs are used, it is suggested to address the serial peripherals from 4 on in order to always
identify which detector has given the alarm.
Shouldn't it be so, the satellite could communicate the opening of zone 1 and it wouldn't be possible to
identify clearly which detector has given the indication, if the cabled one at input 1 or the peripheral
with address 1.
This kind of connection (only possible with XSATHP SERIAL way, allows to
recognize the alarm status but not the tamper status. The zones programmed in
this mode must be ended by a 4.700 ohm resistance. The opening or short-
circuit of the zone causes an alarm indication.
The inputs not used must be necessarily balanced.
The protections of the system must be carried out using the dedicated TAMPER
line which must be balanced by a sole terminal resistance of 4700 ohm.

This kind of connection allows to recognize both the alarm and the tamper status,
using the same zone circuit.
The zones programmed in this mode must be ended by two 4700 ohm resistances
The first resistance identifies the zone alarm whilst the second identifies the tamper.
Referring to the side picture, opening the contact, the satellite detects the general
alarm status of the detector whilst the short-circuit or the cut of the zone itself causes
a tamper alarm, even at system disarmed.
Example:
As example, we show here the connection of two generic detectors to two input
zones at double balancing.
The opening of the n.c. ALARM contact causes an alarm status
The opening of the n.c. TAMPER contact or a short-circuit causes
the tamper alarm of the corresponding input zone.
