OPTIONAL EXPANDER MODULE, ZONES, SIRENS, AUDIO BOX AND WIRED DETECTORS WIRING
A. Back Unit
B. Expander
Note: The Expander module is an optional module.
If this optional module is not used, a small 4-
terminal strip is used instead (2 terminals for wired
1
zones and 2 terminals for the siren)
C. Site internal siren or strobe 6-12 VDC,
150 mA Max.
D. Site external siren MG441PDS or similar siren 12
VDC (nominal) 350 mA Max.
E. Voice box
F. Connect wired detectors as illustrated.
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
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. 5.7).
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-30 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.

4. PowerMaster-30 G2 INSTALLATION
Notes:
To prevent interference of detector operation when
using a control panel with a cellular modem, the
wired detector should be installed at least 2 meters
away from the control panel.

Regarding zones , the control panel "sees" a specific
resistance according to the event, as follows:
Normal (no alarm and no tamper): 2.2 k

Alarm event: 4.4 k
Tamper event: Infinite resistance
