The Unified Siren Control System lets you activate, schedule, and monitor any number of sirens across physically separate locations — from a single centralised control point over a network.
Large industrial campuses, multi-building factories, and distributed pipeline networks all face the same challenge: sirens are spread across physical locations, but activating them requires someone to be physically present at each one.
Triggering sirens at Gate 1, Building 3, and the storage yard simultaneously requires either wiring across the entire campus or three people in three locations at the same time — neither is practical.
Manual siren systems leave no record. When did the emergency siren fire? Which zone? Who triggered it? For OISD/ERDMP compliance, an event log is mandatory — and impossible with standalone systems.
You don't know if a siren at a remote location is working until you need it and it doesn't fire. Without health monitoring, siren failures go undetected until an emergency exposes them.
The system uses a Master–Slave network topology. One Master unit runs the central control software. Multiple Slave units are installed at each siren location. All units communicate over your existing network — LAN, Wi-Fi, or GSM.
Installed at your control room or safety officer's station. Runs the dashboard software. Sends commands to all Slave units. Records all events. Monitors system health in real time. One Master manages all connected Slaves.
One Slave unit per location. Each Slave connects to the local siren (220V AC, up to 5A). Receives commands from the Master and actuates the siren. Reports status back. Minimum 2 Slave units required per installation — one Master is in addition to this.
Master and Slave units communicate over your facility network. For locations without LAN access, GSM connectivity is supported. No new cabling required between Master and remote Slave units.
Traditional multi-zone siren control uses a single ASC panel with hardwired connections to each siren. This works well when all sirens are within 200–300 metres of the panel. Beyond that, cable costs and voltage drop become significant. The Distributed Siren Actuation System eliminates the cable run entirely — each Slave unit is powered locally from the nearest 220V supply, and commands travel over the existing data network at negligible cost.
Activate any siren, any zone, or all zones simultaneously with a single click from the Master dashboard. No physical presence required at remote siren locations.
Configure custom siren patterns for each zone: duration, on/off cycles, repeat count. Different patterns for shift change, fire alert, gas leak, and all-clear.
Pre-programme siren events by time and date. Shift change sirens fire automatically at scheduled times — no operator action required once programmed.
Complete audit trail of every siren activation — time, date, zone, trigger source (scheduled/manual/emergency). Downloadable for compliance reporting and safety audits.
Real-time status of every Slave unit on the dashboard. Instant alert if any unit goes offline or loses connectivity. Know your sirens are ready before you need them.
Dashboard software access is included with the system for the first year. Annual service renewal applicable from Year 2 onwards, with continued updates and support.

Multi-building plants where sirens span 1–5 km across — all activated simultaneously from the control room.
Remote unmanned pump stations along a pipeline — central control can activate sirens at any station for maintenance or emergency.
Group companies with factories in different cities — head office can trigger emergency sirens at any site instantly.
Secure campuses where centralized alert systems are required with a full event log for compliance and accountability.
Be aware of these product specifics before placing an order — they affect installation planning.
The system requires a minimum of 2 Slave units plus 1 Master unit per installation. A single-slave installation is not supported. Plan your network topology accordingly before ordering.
Each Slave unit can directly drive sirens rated up to 220V AC, 5A. For motor sirens above this rating, an external contactor or starter is required at the siren location — this is supplied separately and is not included with the system.
Software access, system updates, and technical support are included for the first year. From Year 2 onwards, an annual service renewal fee applies. Renewal ensures continued dashboard access and support.
