Smoke detector RM 4000 for hold-open systems
Together with the RZ-24 central unit
Characteristics
- Optical smoke detector tested according to EN 54-7
- Operated together with the RZ-24 central unit which supplies the necessary voltage to the detector and simultaneously evaluates it
- Can be used in a temperature range from -40 °C to +70 °C
- Very low false alarm rate thanks to special sensor chamber and the use of algorithms for interference filtering
- If the detector is dirty to the point where it can no longer compensate, it will immediately change to alarm and the fire closures will reliably be closed
- No relay is required in the detector itself, which reduces costs
- Single operating states are indicated via integrated LED with 360º visibility in two colors (red/yellow) and different flashing frequencies
- The smoke detectors RM 4000 must be replaced after 8 years at the latest, even if the detectors are still working properly during the function or maintenance test. This ensures that the hold-open system is always fully funtional and that doors close reliably in the event of a fire
Product details

Status indications
The various operating states of the RM 4000 smoke detector are indicated by an LED. This LED lights up yellow or red depending on its status.
LED red | LED yellow | Function |
---|---|---|
Flashes 1x/sec | No flash | After switching on the power supply (or inserting the detector into the socket): confirms correct wiring. Phase duration: 4 minutes. During this start-up phase, a quick functional test is possible within few seconds. During normal operation it takes longer. |
Permanently on | No flash | Alarm |
No flash | No flash | Normal operation |
No flash | Flashes 1x/sec during start-up | If the yellow LED flashes instead of the red LED during the first 4 minutes after switching on or inserting the detector, the detector has reached the drift compensation limit. |
No flash | Flashes every 4 seconds after start-up | Sensor no longer functions properly and detector has to be replaced immediately |
Installation
Installation notes
Installation information for the base
The bas has specially shaped fixing holes that allow an easy and fast installation. Two hole distances are available: 51 mm and 60 mm. There is a mark on the exterior of the base to indicates the position of the LED once the detector has been fitted. This ensures that the detectors are aligned uniformly when the base is mounted.
Wiring is possible both from the back or the side (knock-outs in the base).
A marking inside the base indicates how long the cable needs to be stripped. The 5 connection terminals are arranged in such a way that there is sufficient space for the wiring work. The terminal screws are captive screws and will not fall out of the terminals. The base is supplied with the screws unscrewed, which makes the wiring work even easier.
The detector is locked into the base by simply turning it clockwise. An additional anti-theft feature is included. A missing detector means alarm.
Wiring diagram
The number of required lintel and ceiling detectors is determined by the applicable national regulations in each respective country. In Germany it is based on the DIBt approval or type approval. In other European countries without national directives the EN 14637 serves as orientation.
The smoke detectors are simply wired in line. A resistor with 3.9 kΩ resistor has to be installed in the last detector of the loop.
The hand switch (if the RZ-24 central is not installed in a position where the hand switch on its cover could be used) needs to be placed in the wiring to the first detector. This allows for a simple, linear wiring.
Installation accessories
The mounting brackets allow a simple installation of the smoke detectors on walls. According to the DIBt requirements for the installation of fire detectors, it is permissible in exceptional cases to replace ceiling detectors with wall detectors. The prerequisite is that the horizontal distance between the wall and the axle of the detector must be 0.5 m. The mounting bracket, part no. 040575 meets this demand. All fixing holes correspond to those of the bracket part no. 040570.
