Managing alarms/system arming/auxiliary channel generation management
In this mode, two independent contact lines can be connected to the interface. The
corresponding addresses must be specied in positions Z1, N1, and Z2, N2.
The congurator in position MOD1 and MOD2 species the type of contact for the
generation of the alarm, as per the following table:
Congurator Sensor connected
none NC contact
1 NC contact - balanced
2 NC contact - delayed (1)
3 NC contact – delayed and balanced (1)
4 Contact NC and contact status forwarding
5 Contact NC balanced and contact status forwarding
6 Contact NC delayed and contact status forwarding
7 Contact NC delayed balanced and contact status forwarding
8 NO contact
9
NO contact for system arming from remote N.O. pushbutton (2)
AUX NC contact – forwarding of contact status (3)
Notes:
(1) Follows the delay set on the central unit:
this function is only available with central units item 3486, 3485/B, item
HC/HD/HS/L/N/NT4601, 067520 and 573934/35. With central units item
L/N/NT4600/4 the interface must be allocated to ZONE 1, with a time delay set (see
the central unit conguration).
(2) The system is activated when the pushbutton is pressed for a minimum period of 3
seconds.
(3) This operating mode does not generate an alarm signal, but a contact status signal,
useful for Automation and Temperature control applications (automatic switching
o of the heating system when a window is open).
Technical alarms management
In this mode, the interface can only manage one contact line connected to the C1
and clamp, to which the NC or NO contact for the generation of the technical alarm
is connected. A NO pushbutton for resetting the generated technical alarm, can be
connected to the - and C2 clamps of the second line. The Z and N address of the interface
must only be specied in the positions Z1 and N1.
Selection of the alarm contact:
Congurator
in MOD1 position
Type of contact
none NC contact
8 NO contact
When a technical alarm with intermittent sound of the indoor siren is generated, it will
also be possible to generate an Auxiliary signal. The channel of the Auxiliary signal is
dened by the numeric value of congurator 1 to 9 entered in the position MOD2. If the
OFF congurator is entered in this position, no auxiliary channel is generated (only the
technical alarm with intermittent sound of the siren).
Technical alarms mode: management of a water detection probe. If ooding occurs,
a sound alarm will be generated by an internal siren, and a signal will be sent to
auxiliary channel no. 3. To reset the alarm press the P pushbutton.
Alarm contacts mode: management of a balanced NC contact line with N.O.
