-
A non-maskable fault will not be signalled if variant 0 is set for an output.
-
After completing the standard and automatic configuration procedures, the EKS type
elements are assigned to a special logical number 0 which makes them inactive.
An illustration of an exemplary implementation of an EKS-4001 element is provided in the manual
called "Designing fire alarm installations using the POLON 4000 interactive fire signalling system" and
the EKS-4001 Installation and Maintenance Manual.
7.5 EWS-4001 MULTI-OUTPUT CONTROLLING ELEMENTS DECLARATION
The EWS-4001 (EWS in short) multi-output controlling element is a line element that enables to
control fire protection devices, e.g. smoke exhaust dampers, doors, sirens, light signalling devices,
etc. The EWS element has 8 relay control outputs. Up to 20 EWS elements may be connected to a
single detection line.
The EWS proper programming consists in declaring a line element (similarly to fire warning devices)
and assigning it to a logical number.
A logical number for EWS is selected from the 1 ÷ 100 range and assigned to an element in order to
make the EWS actuation variants dependent on different events in the control panel. Each EWS type
element may be assigned only to one logical number and vice versa. As far as the program is
concerned, a logical number for the EWS is an approximate equivalent to a zone for fire protection
elements. The logical number connects the EWS with actuation variants. A logical number or
actuation variant must be assigned to an EWS element.
The EWS-4001 operation depends on assigning output relay actuation variants to different outputs.
The EWS-4001 entire programming procedure includes two stages:
Stage I:
The EWS-4001 declaration consisting in assigning:
-
an element number (1 ÷ 127) using the automatic configuration or the configuration with
verification or the manual configuration procedures;
-
a logical number (1 ÷ 100).
Stage II:
The EWS-4001 logical configuration consisting in assigning:
-
a variant for each output of the previously assigned logical number (see below);
-
a set of assigned zones for each output if it is required by a given variant (from the 1 ÷ 1024
range; from own control panel or control panels of the common detection area).
Variants of activating individual EWS-4001 relay outputs
Table 7.2 presents the EWS output programming possibilities. The "control panel number" parameter
(only for control panels operating in a network) has the following meaning:
-
control panel number = 0 shows the dependence on an event in any control panel included in
the common detection area;
-
control panel number > 0 shows the dependence on an event from a given control panel
(provided it is included in the common detection area);
-
control panel number ”―” allows for making actua]on dependent only on local control panel
events.
For variants with additional zone dependencies: zone number = 0 shows the dependence on the total
number of events within all zones in a selected control panel included in the common detection area.
