A.
Back Unit
B.
Expander
C.
Internal siren or strobe 6-12 VDC,
150 mA Max.
D.
External siren MG441PDS or similar siren 12 VDC
(nominal) 350 mA Max.
E.
Voice box
F.
Connect wired detectors as illustrated.
Note:
The wired detector should be installed at least 2
meters away from the control panel.
Regarding the two wired zones, the control panel
classifies the events according to the resistance it
measures as shown in the table below.

Notes for EXPANDER module wiring:
*
Wired
zone
terminals can be connected to a normally closed contact of a detector, switch (for example a Tamper
switch of any device), or a pushbutton, via a 2.2 K
resistor. The 12V terminal can be used to supply 12V (up to
36mA) to a detector (if necessary).
** The EXT terminal can be used to trigger an external siren.
The INT terminal can be programmed for an "internal siren" or "strobe" (see par. 4.7).
The 12V and "GND" terminals can be connected to a siren (for constant DC power supply).
*** The.12V supply to the PGM device is fused. Current is limited to 100 mA.
WARNING! When plugging terminals back into place, be sure to align them carefully with the pins on the PCB.
Misaligned or reverse insertion of terminals may damage internal PowerMaster-33 G2 circuits!
IMPORTANT!
The terminals for internal and external sirens are DC outputs intended for 12V sirens. Connecting a
loudspeaker to any of these outputs will cause a short circuit and will damage the unit.
