Smoke-control operation
The CPS-P1-020 receives fire-alarm or compatible manual smoke-control signals through its monitored fire lines.
When a fire signal is received, the panel gives priority to the fire-mode sequence and commands the nominated windows, louvres, rooflights or smoke hatches to move to their required smoke-control position.
The two monitored fire lines and two ventilation groups allow separate zones or operating groups to be managed within one panel.
Natural ventilation operation
The panel can also operate connected openings for normal day-to-day ventilation.
Compatible control inputs can include:
- open and close wall switches;
- rain sensors;
- wind and rain sensors;
- temperature controls;
- low-level BMS interfaces; and
- other approved external control signals.
Fire-mode commands retain priority over natural ventilation controls.
High-current actuator control
The CPS-P1-020 is designed for applications requiring substantial actuator capacity within a compact control-panel format.
Up to 20 A can be allocated to an operating group, making the panel suitable for:
- multiple window actuators operating together;
- large rooflights and smoke hatches;
- high-current louvre or façade-opening systems;
- industrial natural ventilation systems; and
- centralised groups of compatible 24 V DC drives.
The connected load, starting current, simultaneous operation, cable length and voltage drop must be calculated as part of panel selection.
Main/Sub panel networking
The CPS-P1-020-0202 can be connected to a compatible D+H Main/Sub network.
Up to 16 compatible CPS-P panels can operate as a coordinated network, allowing control capacity to be distributed throughout the building while retaining shared fire-mode and natural ventilation functions.
The CPS-P1-020-0202-B is intended for standalone operation and does not provide Main/Sub networking.
Expansion interface
The CPS-P1-020-0202 includes an integrated expansion interface for compatible D+H functions and accessories.
This allows additional control, indication or interface functions to be incorporated where required by the project.
The standalone CPS-P1-020-0202-B does not include the same network and expansion functionality.
Standby batteries and mains power failure
The CPS-P1-020 is supplied with monitored standby batteries to maintain control-system operation when the normal 230 V AC mains supply fails.
Where automatic close on loss of mains power forms part of the operating strategy, the panel commands the connected openings to close and remains available to respond to a subsequent fire signal during the standby period.
The battery capacity must be confirmed against the connected actuator load, required standby period, operating sequence and project requirements.
Typical system arrangement
Normal ventilation:
Wall switch, weather sensor or approved external control → CPS-P1-020 → nominated opening group opens or closes
Fire operation:
Fire-alarm input → CPS-P1-020 → nominated smoke-control openings move to their required position
Loss of mains power:
Standby batteries maintain panel operation → connected openings follow the configured power-failure sequence
Networked arrangement:
Main CPS-P panel → Main/Sub network → distributed CPS-P panels and their connected opening groups
Drive capacity and system selection
Panel selection should account for:
- the selected actuator models;
- the rated and starting current of each actuator;
- the number of actuators connected to each group;
- the total connected load;
- simultaneous operating requirements;
- cable length and voltage drop;
- the required fire lines and ventilation groups;
- standalone or networked panel operation;
- the required standby period;
- building-system interfaces; and
- the approved cause-and-effect sequence.
Integrated enclosure
The CPS-P1-020 is supplied in an integrated light-grey plastic enclosure with an IP54 protection rating.
The panel location should provide:
- suitable structural fixing;
- clear power, actuator and control-cable entry routes;
- electrical working space;
- access for testing and commissioning;
- access for battery replacement; and
- future maintenance access.
System coordination
The panel is selected and configured together with the automated openings, actuator loads, field cabling, fire-alarm interfaces, natural ventilation controls, standby power and approved cause-and-effect sequence.
EBSA works with the project team to coordinate these elements with the fire strategy and relevant design requirements.
