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 ÷ 80 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.
The EWK-4001 entire programming procedure includes two stages:
Stage I:
EWK-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 ÷ 80);
-
an operation mode (it is factory set but may be changed - see below).
The EWK-4001
operation mode
defines the operation method (standard mode in bold print) for
individual 1 - 8 inputs:
-
NO
– shows characteristic resistance closing in order to generate an alarm;
-
NC
– shows a characteristic resistance opening in order to generate an alarm.
Stage II:
The EWK-4001 logical configuration consists in assigning (with a previously defined logical number) the
following elements to each input:
-
variant (see below);
-
fire alarm zone (if required by the variant);
-
technical alarm message (if required by the variant).
The EWK-4001 input monitoring variants
Variant 0
Means inactive input (no signals from the input are received).
Variant 1 –technical alarm input
The input activation by specific resistance clench or opening (depending on the input settled operation
mode) causes technical alarm evoking in the
control panel.
