Connection of manual call points
The following manual call points can be connected to a conventional detector interface of the fire detec-
tion control panel:
Description
Type
Manual Call Point Series HFM/HM
HxM/x/11/xx
Manual Call Point Series HFM/HM – 1 auxiliary contact HxM/x/12/xx
Manual Call Point Series HME
HME/FFFF/11/TT/LL/x
Manual Call Point Series HME – 1 auxiliary contact
HME/FFFF/12/TT/LL/x
Manual Call Point/Red/Standard
UNI3021C
Manual Call Point Series C31
C31
Each manual call point has a built-in alarm resistor (R = 1kOhm/0.35W). In the last manual call point,
an end-of-line resistor (Rab = 5.6kOhm) has to be installed.
The end-of-line element can be changed in the parameter setup of the Fire Detection Control Panel
(BC06/BC016/BC600). The factory setting is Rab = 5.6kOhm.
All diodes that are not denoted are of type 1N4004.
2.2.1
Connection of HFM/HM
Old version of the Manual Call Points HFM/HM
Old manual call points HM/HFM/x/12 can be distinguished from new ones by means of the following
characteristics: at the top left of the componentry, old manual call points HM/HFM/x/12 have a ter-
minal strip with 4 terminals (1 through 4), new ones have a terminal strip with 6 terminals (1 through
6).
Connecting the mains voltage 230VAC to the change-over contacts 7, 8 and 9 is only permissible
for the type HM/HFM/x/12/xx/N (with N standing for mains voltage)! It differs from the type
HM/HFM/x/12/xx in that it has additional covers for the insulation of the mains voltage. The
instructions on the safe use, which can be found in the enclosed packet, must be strictly
observed!
