Apollo Marine DIN-Rail Sounder Controller (8 Amperes) – 55000-181MAR
Please note: The Apollo 55000-181MAR is currently subject to an extended lead time. Apollo recommends the 55000-182APO DIN-Rail Sounder Controller (5 Amperes) as the closest available alternative.
The Apollo 55000-181MAR Marine DIN-Rail Sounder Controller (8 Amperes) is designed to control a zone of externally powered sounders and report their operational status back to the fire alarm control panel. Compatible with Apollo XP95, Discovery and CoreProtocol® systems, the module provides a reliable interface between the fire alarm loop and external notification devices.
For installation, the 55000-181MAR must be mounted on a DIN rail inside a suitable enclosure, such as the Apollo 29600-239 or 29600-240 enclosure, and secured using appropriate end stops.
