SYSTEM ACTIVATION FAILURE
This chapter describes the causes that prevent the activation of the alarm system, indicating any remedies to be taken.
An
EN50131 compliant
intrusion alarm system cannot be set by the User if certain blocking conditions are present.
There are also conditions that can be inhibited which may be overridden and bypassed by means of specific manual commands
imparted by the User or by the Installer.
The following describes both blocking conditions and conditions that can inhibited.
3.1
BLOCKING CONDITIONS
Conditions that always automatically prevent setting (regardless of the control device that requested activation).
The conditions that block the system are:
Open and non-excludable instantaneous intrusion input
Open and non-excludable tamper input
Open and non-excludable pre-alarm input
Open and non-excludable detector failure input
Open and non-excludable siren failure input
Unbalanced and non-excludable balanced or double balanced input (any customisation)
Input conditions only prevent the setting of the zones associated with them.
The conditions that prevent the setting of any zone are the following:
Bus failure
No communication with a wired device or a communicator or lack of radio supervision
Control panel tamper, radio device or wired device
24-hour inputs (open) (control panel SAB or wired expansion)
Jamming on radio module, radio interface or GSM/GPRS module
Control panel battery failure, radio device
+SR failure
Control panel power supply failure
Bus power supply voltage failure
+V1 failure
+V2 failure
Bus device failure
Loss of mains failure
PSTN module fault (available only with 1068/005 control panel)
GSM /GPRS fault
IP interface fault
3.2
CONDITIONS THAT CAN BE INHIBITED
The conditions that can be inhibited may be overridden and bypassed by means of specific manual commands imparted by the User
or by the Installer.
3.2.1
Conditions that can be inhibited on inputs
The input conditions apply to inputs associated with at least one of the zones for which activation is required.
The conditions requiring inhibition are as follows:
Open and excludable
instantaneous intrusion
input
Open and excludable
tamper
input
Open and excludable
pre-alarm
input
Open and excludable
Detector failure
input
Open and excludable
Siren failure
input
Unbalanced and excludable balanced or double balanced input
(any customisation
)
Inhibitions can be confirmed by any user.
