DORMA RMZ
Installation arrangement of the RMZ lintel-mounted
smoke detector for applications where the bottom
surface of the ceiling is less than 1 m above the
bottom edge of the lintel on one or both sides of the
door. ☞1)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. ☞1)1)

1)
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
pushbutton in accordance with the drilling template.
Install the necessary cabling.
In order to comply with protection class II (total
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.
Terminal assignment
Connect hold-open device(s) to terminals.
Connect any ceiling-mounted detectors and/or
manual pushbuttons – see connection diagrams.
Terminal resistors must be properly installed!
Insert and connect smoke alarm module (option).
The alarm module cannot be used if relay contacts 7,
8 and 9 are already in use.
Connect the power supply cable. Close the shock
hazard protection cover and screw down.
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

• 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/Bminiature 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.
• he power cable (NYM) conductor cross section should
not be greater than max. 1.5 mm2. The PE
conductor 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). ☞1)
• 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.
