(AND of two alarms generates true alarm). If no alarm has occurred within these 3 seconds, ALPHA 2 will cut the power of the relative line for a time corresponding to reset allowing physical reset of detector in alarm. -
Page 13: Enable Configuration
Page : 13/32 4- CONFIGURATION OF PANEL ALPHA 2 is equipped with a non volatile memory on which all the parameters of configuration reside. Some of these parameters can be modified by the installer, in agreement with normative, in order to adapt the panel to the necessities of the installation. -
Page 14: Base Configuration
For the visualization/modification of each parameter, refer to the next pages. 4-2 BASE CONFIGURATION The factory configuration of ALPHA 2 complies with EN 54-2. Before carrying out any modification of the configuration it is necessary to refer first to the standard normative in order to avoid an improper operating setting. - Page 15 If within this time a new alarm occurs on another zone it is registered as a true alarm (AND of two alarms generates true alarm) but if 3 seconds delay has expired ALPHA 2 will apply a reset on detection lines.

Page 16: Verify/Modify Configuration Of Delays
In pre alarm conditions the alarm outputs are not activated. If ALPHA 2 has a factory setting (can be modified in par.4-5) the pre alarm will be managed like alarm delayed, it means that after an internal countdown that starts when pre alarm had occurred the pre alarm becomes alarm. - Page 17 OPERATING & INSTALLATION Index MANUAL - Rev.2 Date : 30/07/2007 Page : 17/32 NOTA: It is possible to set aux. outputs as repetition of pre alarm (see par.4-5) Select with the key [SA], [SB] the time you want to be applied (0 to 150 sec.)

Page 18: Verify/Modify Configuration Of Options
If on, it indicates that a fault condition (except from CPU fault) will activate general pre alarm (If pre alarm mode is set in temporised mode, ALPHA 2 will activate the countdown corresponding to delay of alarm, so that general alarm will be activated by the end of the countdown). - Page 19 OPERATING & INSTALLATION Index MANUAL - Rev.2 Date : 30/07/2007 Page : 19/32 NOTA: It is necessary to choose the option C (factory setting) to comply with EN normative as automatic reset of alarm outputs is prohibited; it is required to reset manually the alarm actuators.
