When the primary power supply is available, the device supplies the loads directly from the mains and monitors the battery charging process under the control of a microprocessor-based controller. When the mains voltage fails or the PWP is activated, the power supply executes a strictly programmed operating sequence.

It is possible to set an immediate switchover (25 ms) or a 2 s delay. A two-second delay prevents gate controller processors from freezing during short-term, unstable fluctuations in the mains voltage. Completely disconnecting the power supply before starting the inverter ensures a proper controller restart.

After switching to battery power, the power supply maintains 230 V AC for the duration of TS (9 minutes by default). This allows the gates to be opened or closed if necessary during normal operation. If no fire alarm signal is received during this time, the inverter is switched off and the power supply enters standby mode. This state can be maintained for up to 72 hours.

The alarm signal from the Fire Alarm Control Panel (FACP) is supplied to the supervised, parameterized CIE input. The signal must remain active for more than 2 seconds. This eliminates the risk of false alarms caused, for example, by electromagnetic interference. After the signal has been verified, the alarm is permanently latched in the controller memory. This ensures that the gate opening procedure is completed even if the signal cable from the FACP is damaged.

The CSO fire output transmits a control signal to the gate drive (or the RWA input). Using slider No. 7, this signal can be delayed by 2 s or 12 s. The 12-second delay is intended for gate controllers that require time to initialize the system and correctly read the limit switch states after a sudden start. After the gate has been raised and the alarm time TA (9 minutes by default) has elapsed, the voltage at the 230 V AC output is unconditionally disconnected, minimizing the risk of electric shock to firefighters conducting firefighting operations.

Most fire protection devices powered by 230 V AC (e.g. gate drives) remain inactive in standby mode and do not draw power from the mains. Continuously maintaining the inverter output voltage during a prolonged loss of the primary power supply would unnecessarily drain the batteries.

Thanks to the energy-saving function, after the TS period (9 minutes) has elapsed following a mains failure, the ZUP-230V-BM microprocessor controller completely switches off the inverter output. The current drawn from the batteries for the power supply’s own operation then drops from 0.59–1.44 A (depending on the model power rating) to just 39 mA. The inverter is automatically reactivated and supplies the full 230 V AC voltage only when a fire alarm signal is received from the FACP loop (CIE input) or when manually triggered (DO input). This solution makes it possible to meet the normative requirement for 72 hours of standby time while maintaining optimal battery capacities.

The ZUP-230V-BM fire safety floating-operation power supply is a specialized device that eliminates the drawbacks of standard UPS systems in smoke control systems. By generating a pure sine wave, it protects gate drive motors from damage, while its advanced microprocessor-based logic with an inverter shutdown function ensures a long fire standby time. Full CNBOP certification confirms that the device is a reliable component of technical safety systems and complies with Polish construction law.
