Effective facility monitoring must be accessible at all times for maintenance personnel. To enable convenient visual and audible displays of system states or events on-site, universal and durable annunciator systems are essential.
EES offers a comprehensive portfolio of monitoring products that integrate seamlessly into existing structures.
EES annunciator systems support a wide range of applications. With research, development, production, and sales centralized at our headquarters in Germany, we respond quickly to customer needs and remain at the forefront of technological advancements.
Backed by over 40 years of experience in diverse global applications, EES products are trusted in substations, transformer stations, facility monitoring, site monitoring, industrial facilities, pumping stations, and more.
Our portfolio includes annunciators for tasks of virtually any scale. From simple indication devices to networkable annunciator systems with communication interfaces compliant with IEC 61850 and IEC 60870-5-101/104 standards, EES products combine high functionality with user-friendly operation.
STANDARD FAULT ANNUNCIATORS
For simple indication or monitoring tasks the EES portfolio offers different standard fault annunciators for panel mounting to visualize operation or alarm conditions. Depending on the type first-up or new-value processing, NO or NC triggering, as well as the assignment to collective reports can be configured. The general alarm processing is otherwise fixed.

BASIC FAULT ANNUNCIATOR BSM-C
- 2nd generation available
- Easy and flexible customizable for your application
- Scalability up to 192 signal inputs

INDICATION MODULES LAB
- Minimized energy consumption of max. 1W
- Easily interchangeable colors
- Maximization from 8 and 16 to up to 48 signal inputs
- Increased protection level IP54
- Wide range 24 – 230 V AC/DC

STANDARD FAULT ANNUNCIATOR SSM
- Standardized fault alarm sequence
- Fixed, predefined settings (SSM-C)
- Parameterizable via DIP switch (SSM-A)
- 1:1 alarm forwarding with relay module (SSM-R)
- Combined operation/malfunction indicator (LSM-C)
FAULT ANNUNCIATORS WITH EXTENDED FUNCTIONALITY
Fault annunciators with enhanced functionality are predestined for the solution of complex requirements not only by the expandable design. In a cluster consisting of several cascaded fault annunciators larger plants or fields can be monitored. In contrast to the standard fault annunciators, comprehensive manipulations of each channel can be carried out.

BASIC FAULT ANNUNCIATOR BSM-P
- 2nd generation available
- Easy and flexible customizable for your application
- Scalability up to 192 signal inputs

DROP-FLAP ANNUNCIATOR FSM
- Permanent display even on power failure
- Internal horn and history- /event memory
- Individual parameterization via software possible

WINDOW ANNUNCIATOR PANEL WAP
- Parameterisation of window colours and sizes via browser – without mechanical work
- Integrated relay outputs optional
- Cascading of WAP or BSM slaves to increase the number of alarms
FAULT ANNUNCIATING SYSTEMS WITH PROTOCOL
Fault annunciating devices with standardized protocol provide on the one hand the serial or networkable acquiring of plant conditions and the corresponding display of the respective signal input, as well as the forwarding of parallel to in- or output messages to superior systems. From SCADA Systems even single or double commands can be carried out via relays triggered by protocol telegrams. The systems of this group present as an I/O device the ideal form of a “ragman”.
