www.pulsar.pl EN54C RED POWER plus 4. Installation. 4.1. Requirements. The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required for a given country) for ~230 V in and low-voltage installations. As the power supply is designed for a continuous operation and is not equipped with a powerswitch, therefore, an appropriate overload protection in the power supply circuit should be provided.
www.pulsar.pl EN54C RED POWER plus 4.2. Installation procedure. CAUTION! Before installation, cut off the voltage in the 230 V power-supply circuit. To switch power off, use an external switch, in which the distance between the contacts of all poles in the disconnection state is not less than 3mm. It is required to install an installation switch with a nominal current of 6 A in the power supply circuits outside the power supply unit. 1.
www.pulsar.pl EN54C RED POWER plus 4.3. Procedure for checking the power supply at the place of installation. 1. Check the indication displayed on the front panel of the power supply unit: a) The 230 V LED should remain lit to indicate the presence of the mains supply voltage. b) The 230 V LED should remain lit to indicate the presence of the supply voltage. 2. Check the output voltage after 230 V power failure. a) Simulate the lack of 230 V mains voltage by disconnecting the main circuit breaker.

Technical outputs.
www.pulsar.pl EN54C RED POWER plus ALARM - technical output of collective failure indication. Output indicating collective failure. In the case of 230 V power failure, battery circuit failure, PSU failure, or EXTi input activation, the collective failure signal ALARM will be generated.

www.pulsar.pl EN54C RED POWER plus 5.4. Indication of the enclosure opening - TAMPER. The PSU is fitted with the microswitch tamper indicating enclosure opening. The tamper cable is not connected to the terminal in the factory settings. In order to activate tamper, remove the jumper from tamper terminal and plug in the tamper cable. Each opening the enclosure will generate a failure signal at the ALARM technical output. Fig. 12. TAMPER technical output. 5.5. PSU overload.
www.pulsar.pl EN54C RED POWER plus 5.7.2. Cooperation with electric actuators - EN54C-LS4 and EN54C-LS8 sequential modules. The sequential modules are designed for use with electric actuators without return spring (EN54C-LS4) and with electric actuators with return spring (EN54C-LS8) used for fire dampers and smoke vents. These devices are used in fire alarm systems and smoke and heat control systems.
www.pulsar.pl EN54C RED POWER plus 6. Reserve power supply circuit. The PSU is fitted with intelligent circuits: battery charging circuit with the function of the accelerated charging and battery control, which main task is to monitor the condition of the batteries and the connections in the circuit. If the controller detects a power failure in the battery circuit, appropriate indication and change of the ALARM technical output. 6.1. Battery detection.
www.pulsar.pl EN54C RED POWER plus Fig. 14. Mounting of the temperature sensor. The nominal battery operating temperature recommended by many manufacturers is 25°C. Working at elevated temperatures will significantly shorten the battery lifetime. The service life is reduced by half for each sustained temperature rise of 8°C above the nominal temperature. This means that the battery lifespan, when operated at 33°C, can be decreased by 50%! 6.8. Standby time.

The PSU does not require any specific maintenance, however, its interior should be cleaned with compressed air if it is used in dusty conditions. In case of fuse replacement, use only compatible replacement parts. Technical inspections should be carried out not less frequently than once per year.
