The output activation is performed in the case of a 2
nd
stage alarm occurrence in at least two zones
that are assigned to this relay.
Variant 7 – reset output
The reset output is provided in order to generate a resetting impulse, lasting for ca. 1.5 s, after fire
alarm reset. This type can be utilized for instance for power supply and reset of detectors that
require a separate power supply, e.g. flame detectors manufactured by Det -Tronics.
Note:
Variant 7 is active only for the EWS element outputs 1 and 2.
Output relay actuation variants are programmed only for a EWS that possesses a logical number.
In the case of variant 2 and variant 5 application, at least one zone should be assigned to the EWS,
whereas in the case of variant 3 and variant 6 application, at least two zones should be assigned.
Variants 1 and 4 do not require any zone assignation.
In variants with zone dependence, the assigned zones can be …….. from own control panel (in the
case of independently operating control panel) or from any control panel of the common
supervision area In the case of control panel network.
The total assignments of zones to all executive outputs and SAL type elements in the control panel
should not exceed 64,000.
Note:
After the standard configuration loading and automatic configuration performance, EWS elements
are assigned to a special logical number 0, and after a number attribution, variant 0 is assigned,
which causes that such an element is inactive.
Detailed information concerning the EWS element is contained in the EWS-4001 ‘Installation and
Maintenance Manual’.
7.6 EWK-4001 MULTI-INPUT MONITORING ELEMENTS DECLARATION
The EWK-4001 (EWK in short) multi-input monitoring element is a line element with 8 monitoring
inputs. An EWK element makes it possible to monitor the condition of fire protection devices, .e.g.
smoke exhaust dampers, doors, sirens or other technical devices and receive fire alarms depending
on the configuration. Up to 20 EWK elements may be connected to a single detection line.
Depending on the characteristic resistance, each input may indicate one of the three following
modes:
1.
quiescent (operation);
2.
fault;
3.
(technical or fire) alarm.
The EWK proper programming consists in declaring a line element (similarly to fire warning devices)
and assigning it to a logical number.
A logical number for EWK is selected from the 1 ÷ 100 range and assigned to an element
in order to make the EWK actuation variants dependent on different events in the control panel and
assign the required user messages to it. Each EWK 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 EWK is an
approximate equivalent to a zone for fire protection elements. The logical number connects the EWK
with monitoring variants and user messages for monitoring inputs.
The EWK-4001 operation results from the operation mode programmed for an element and the input
monitoring variant.
