The Simplex 4603-9101 is an LCD remote annunciator for Simplex addressable fire alarm control panels. Specifically, it displays alarm, supervisory, and trouble events at locations away from the main panel.
In addition, the LCD shows event text exactly as it appears at the host FACP. As a result, responders and security staff can identify the device and zone in alarm without walking to the main panel.
What the Simplex 4603-9101 Does
First, the annunciator connects to the host panel over the Simplex annunciator (RUI) bus. Then, it mirrors the panel’s event display in real time. Therefore, the same custom point labels and zone descriptors that show on the panel also appear at the remote location.
Furthermore, the unit is typically installed at building entries, fire command stations, or guard desks. As a result, it gives arriving fire department personnel an immediate read on the system’s status.
Typical Installation Locations
- Main building entrance or lobby for fire department use
- Fire command center or building engineering office
- Security desk or 24-hour staffed station
- Tenant suites in multi-tenant high-rises
