Heat detector WM 3000+ (Replacement)

Heat detector WM3000+ hold-open sytems fire protection doorswith RS 3000 Relay Base for Hold-Open Systems

DICTATOR WM 3000+ heat detectors have been used in hold-open systems to automatically close fire protection doors in the event of alarm.

This detector is among others included in the following approvals: Z-6.5-1903, Z-6.5-1707.

To ensure the correct functioning of the hold-open system, the DICTATOR smoke and heat detectors 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.

Since July 2019, this heat detector may no longer be manufactured in Germany due to the valid regulations of the Institut für Bautechnik. If a WM 3000+ is used in an existing hold-open system from DICTATOR and must now be replaced, a completely new hold-open system RZ-24 with RM/WM 4000 in accordance with the current regulations must be installed.

  • When the hold-open system is replaced with the currently approved hold-open system RZ-24, all smoke and heat detectors must be replaced.
  • The existing power supply unit is omitted and replaced by the RZ-24 control unit.
  • The hold-open device (usually a magnet) is connected directly to the control unit.
  • Possible changes to the wiring or the use of existing cables on site must be checked on the basis of the situation on site.
  • Please refer to the current general type approval for information on whether it is necessary to replace the hold-open device (magnet, door closer, drive).

Rauchmelder Rauchschalter RM 3000 Montage 1When mounting the WM 3000+ smoke detector on fire protection doors, it is imperative to observe the general approval of the building authorities for the hold-open system.

To protect the WM 3000+ smoke detector from pollution during construction work, all detectors are delivered with a red protection cap which must be removed when the hold-open system is put into operation.

At first the socket is mounted. Usually the relay base, part no. 040841 is used. It is part of the 040800NSET set. Only in case of suspended ceilings usually a special mounting socket with frame, part no. 040842, is used. On demand, we gladly will send you more information.

The two slots in the base make it very easy to install it on the ceiling. If the detector has to be mounted on the wall (always in a horizontal position!!!), a mounting bracket has to be used (part no. 040570 or 040575, see point Mounting brackets).

The base has a wide interior diameter and five terminals. Wiring is possible both from the (open) back or from the side (knock-outs in the base).

Electrical connection of the detector(s)
Wiring is carried out according to the adjoining wiring diagrams. The power is supplied by one of the DICTATOR power packs (depends on the power consumption of the hold-open system).

Hand release switch: needs to be placed in the wiring to the first detector.
Hold-open devices (e.g. electromagnet, door closers with electromagnetic hold-open, door operators with integrated hold-open): connection to the last detector in the detector circuit.

After wiring the base the detector is plugged in and turned clockwise. A missing detector of a hold-open system in operating state means alarm and the power supply to the holding devices is interrupted.

IMPORTANT: Protect the smoke detectors from dust, colour mist, moisture etc. to prevent malfunction.
