Fixing Instructions
Technical Data RMZ
Input:
230 V AC +10%/–15%
120 mA / 28 VA / 50 Hz
Output:
24 V DC / 460 mA / 11 W
Type of protection:
IP 30
Protection class:
II
Smoke switch:
24 V DC / 50 mA
Temperature:
–20°C / +40°C
Rel. air humidity:
max. 93% without condensation
Work on electrical equipment and systems may only be
performed by properly trained specialist personnel.
• Check to ensure that the line power supply (230 V AC)
has been disconnected and is no longer live.
• 10 A/B miniature circuit breaker must be provided
in the supply circuit. This can also be used as the
isolator for disconnecting the RMZ and making it
dead.
• The power cable leading to the RMZ must be properly
secured to ensure effective strain relief.
• The power cable (NYM) conductor cross section should
not be greater than max. 1.5 mm
is not electrically utilised. The terminal (PE) should,
however, be used where a PE conductor is provided.
• The RMZ smoke detector should only be installed as a
lintel-mounted unit, and should only be commissioned
once firmly fixed to the wall.
• Fire/smoke detectors controlling hold-open systems
must not be used to actuate any further alarm devices
(e.g. fire alarm transmission systems).
• If the optional alarm module is installed, the cable
connecting it to the smoke switch must be led over and
across the measurement chamber in order to ensure
that smoke penetration is in no way hindered.

sides of the door
1)
See separate sheet for associated connection diagrams.
If the bottom surface of the ceiling is more than 1 m
above the bottom edge of the lintel on one or both
sides of the door, two ceiling-mounted smoke detectors
must be installed in addition to the lintel-mounted

detector.

See separate sheet for associated connection diagrams.
The RMZ lintel-mounted smoke detector is installed
directly above the door opening (min. 10 mm). The
vertical distance above the bottom edge of the lintel/
transom must not be more than max. 0.1 m.
Mark and drill the fixing holes and the necessary cable
lead-throughs for the 230 V power lead, hold-open
device, ceiling-mounted detectors and manual push-
button in accordance with the drilling template.
Install the necessary cabling.
In order to comply with protection class II
insulation), the 230 V power lead should be installed
with double insulation up to the connection terminal.
Remove cable insulation at the end.
Break out the cable lead-through.
Fit end caps and fix the RMZ smoke detector.
