Initialization - UniPOS IFS7002 Instruction Manual

UniPOS
In automated addressing the fire alarm loops' units obtain addresses according to a strictly
specified algorithm and the fire control panel is capable to detect their location later. To be able to
operate in automated addressing mode, a fire detector shall meet the following requirements:
 No short circuit or break up detected;
 Not more than one branch at a single point, i.e. between two consecutive units;
 No branches between the fire control panel and the first (the last) unit;
 No branching of branches.
In manual addressing the fire alarm loops' units obtain addresses as they are determined by the
user. If, while performing manual addressing, the algorithm of the automated addressing is not
followed, the fire control panel will not be capable to detect the units' location later. The only
restriction in manual addressing is explained in section 6.4.2.3.

6.4.2. Initialization

Initialization is a process during which addresses are being assigned to addressable devices in a
fire alarm loop. The initialization can be two types – clear initialization and standard initialization:
 In clear initialization new configuration of the addressable units is entered in the fire alarm
loop
 In standard initialization the fire control panel checks the compliance of the addressable units'
current configuration with the configuration, entered during the clear initialization.
In both types of initialization the switched-off addresses are skipped (in clear initialization of a fire
alarm loop in manual addressing mode this shall be ensured by the user). The option allows reserving
addresses for units, included later in the loop, without re-assigning the addresses of the current units.
6.4.2.1. Clear initialization in automated addressing mode
Clear initialization is done in the following cases:
 Initial start-up of the fire control panel;
 The fire control panel or an output is being switched on at Set Up, when the default
parameters of the control panel are entered;
 The function Clear initialization is being started at Set Up Mode (see section 13.8.2.) – in such
case it is performed only for fire alarm loops which are set to automated addressing.
The addressable units in the fire alarm line, detected by the control panel, are addressed in series
(consecutively), and their parameters (identification number, type and class) are recorded in the fire
control panel.
6.4.2.2. Standard initialization in automated addressing mode
Standard initialization in automated addressing is done for fire alarm loops set to automate
addressing, in the following cases:
 The fire control panel or an output is being switched on at Set Up, when the addressable units'
configuration is registered in the control panel (i.e clear initialization has already been done);
 Start up of the Initialization function, at Set Up Mode (see section 13.8.1).
The location and the parameters (address, identification number, type and class) of the
addressable units, detected in the fire alarm loop, are checked for compliance with these recorded in
the fire control panel.
6.4.2.3. Clear initialization in manual addressing mode
Clear initialization in manual addressing mode is performed during start up of the function Manual
addressing, at Set Up (see 13.4.5); it is performed for a selected fire alarm loop only.
Any non-addressable units detected in the fire alarm loop obtain addresses previously determined
by the user; their parameters (identification number, type and class) are recorded in the control panel.
To ensure successful completion of the action, the fire control panel shall not have access to more
than two units, located in any line of the loop; i.e. if more than one branch is available at a certain
point, units without addresses shall be available in two branches only (in the loop and in one branch,
or in two branches).
6.4.2.4. Standard initialization in manual addressing mode
Standard initialization in manual addressing mode shall be performed for fire alarm loops set to
manual addressing, in the following cases:
