1. General safety instructions 1.1 GENERAL SAFETY INSTRUCTIONS The RZ-24-05 central is a power supply with integrated tripping device for hold-open systems on fire and smoke protection doors. Only trained professionals may effect the installation; e.g. only a qualified electrical technician may connect the power supply to the mains.
If not, an additional detector is required. 2.2 OPERATIONAL LIFE To ensure the correct functioning of the hold-open system, the DICTATOR smoke and heat detec- tors have to be replaced after a maximum of 8 years of operational life. In Germany the DIN 14677 regulates the replacement obligation of fire detectors in hold-open systems.
Magnet (DICTATOR electromagnets EM GD 50 to EM GD 70 - see separate catalogue pages) Push button of the RZ-24-05 central, further push button switches can be connected in the detector loop, e.g. part no. 040005 DICTATOR Technik GmbH · +49 (0)821 246730 · info@dictator.de · en.dictator.de · 20.05.13...
Some parts inside the casing are energized with hazardous voltage during operation! May be opened only by professionals when being de-energized (the power supply of the RZ-24-05 is cut!!) DICTATOR Technik GmbH · +49 (0)821 246730 · info@dictator.de · en.dictator.de · 20.05.13...
IP rating IP 30 IMPORTANT In total the RZ-24-05 central provides 0.5 A for the supply of the con- nected fire detectors, magnets etc. In case the maximum power consumption is exceeded, the RZ-24-05 will automatically switch off. This also happens when it is overheated!
Technical manual: Central unit RZ-24-05 5.2 TERMINAL ASSIGNMENT The RZ-24-05 has 14 terminals. The maximum permissible wire thickness is 0.75 mm². The terminals may only be loosened with a special tool, part no. 040565, which is available sep- arately. A normal screwdriver will damage the terminals!
For this purpose, 24 V are briefly applied to the input. Central closing can be used to close doors (only with electromagnets) without triggering the detection loop of the RZ-24-05. This function is not a closing in case of fire, but only realizes the closing of the fire and smoke protection closures, e.g.
With correct connection => the red LED (3) on the housing lights. Reset the central unit with the RESET button (2) on the housing cover. Now the system is ready for operation. Ill. 5 DICTATOR Technik GmbH · +49 (0)821 246730 · info@dictator.de · en.dictator.de · 20.05.13...
"warning light" output is switched on. LED indicator "Ready" The "ready" LED indicator lights up green when the RZ-24-05 detector loop is ready (not trig- gered). The "electromagnet" output is switched on, the "warning light" output is switched off.
Error Measure Detection loop cannot Check whether the RZ-24-05 can be reset with a 3.9 kΩ resistor be reset on terminals and 2. If not, check whether the control module is correctly inserted in the terminal board. If the problem persists, replace the control module.
