1. Preparations for installation
Open the required cable inlets
– Cut open exposed cable inlets „flat" and do not pierce them
– Use only the lower break-out opening wherever possible for buried cables
– The standard lock can be replaced by the optional security lock.
Undo the retaining screw (Fig. 1/10) in order to exchange the lock.
Important! The cables may be inserted only through lower, exposed inlet into the HFM if
installed outdoors and if using the HFM protective housing – see also Item 6.
2. Installation
Smooth down the mounting surface in order to remove major bumps and irregularities.
Installation height up to pushbutton:
(= floor – lower edge of callpoint
Mark the position to drill the holes using the drilling template (enclosure) and insert 2 F6
dowels. Fit the HFM housing. The callpoint element can be removed – it can be unlocked
with the locating spring (Fig. 1/8).
Insert the cables and strip the sheath from the cables starting directly after the insertion point.
Clean the HFM housing if necessary and insert the callpoint element.
3. Connecting the HFM to:
A. GMG (fixed-threshold detector zones)
– MS 7/9 (current amplification principle)
– MSDW (current attenuation principle)
B. PMG (pulse-polling detector zone)
– MS 8 (pulse-polling system)
C. SIGMASYS – MG
Stow wire slack and reserve wires in the interior of the HFM on the right-hand side wall.
4. HFM identification
Consult the local fire brigade when selecting the location for the ZONE/detector No. to be
attached in accordance with DIN 14675.
Suggested location: Use the free area to the right of the pushbutton (outside of the red
pushbutton marking on the disk).
The manual fire alarm call point (HFM) may need to be provided with a label with corre-
sponding printed information depending on the particular application. The scheduled
location for the label is on the door above the glass disk and is marked by a shallow recess.
5. Commissioning
Please note the information in the control and indicating panel's Commissioning and
acceptance checklist.
6. Inspection
A. GMG (fixed-threshold detector zones)
– Switch the ZONE to inspection, operate the HFM
1. MS 7/9:
HFM LED blinks
2. MSDW:
HFM LED inoperable. Check receipt of signal on fire alarm
control and indicating panel (using a walky-talky)
B. PMG (pulse polling detector zones) and
C. SIGMASYS detector zones detect HFM tripping by means of the door contact in the
case of
1. open HFM door as inspection alarm
2. closed HFM door as alarm
The HFM LED blinks in both cases.
7. Glass disks
The HFM disks are marked with a red bar and dimension „ 78 on one edge. The marking is
not visible from the outside after installing the disk.
