Sounder control units
Apollo manufactures Interfaces, a comprehensive range of intelligent systems. They enable fire protection systems to be engineered simply and effectively without the need for custom-designed equipment.
The sounder control unit is used to control the operation of a zone of conventional sounders and report their status to the control panel.
The unit is isolated as standard and fitted with bi-directional short-circuit isolators so that it is unaffected by a single short circuit on either loop input or output.
Interfaces without isolators are available on request.
• Easy to install.
• Isolated as standard.
