Figure 3.1b – Phone Wiring 
Phone wiring in the UK: Line terminals must be connected to pins 2 and 5 of the wall jack. 
For all installations: If DSL service is present on the phone line, you must route the phone line through a DSL filter 
(refer to MESSAGE TO THE INSTALLER on page 2 for further details). 
3.5.2 Zones and Sirens Wiring 
 Note
Regarding zones 29 & 30, the Control
Panel “sees” a specific resistance
according to the event, as follows:
Normal
 (no alarm & no tamper): 2.2 k
Ω
Alarm event
: 4.4 k
Ω
Tamper event
: Infinite resistance

Figure 3.1c – Zones and Sirens Wiring 
Notes: 
*   Zone 29/GND and Zone 30/GND 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
Ω
 resistor. The 12V terminal can 
be used to supply 12V (up to 36mA) to a detector 
(if necessary). 
**    Both +12V terminals are identical (shorted together).  
The EXT terminal can be used to trigger an external siren. 
The INT terminal can be programmed for an "internal 
siren" or "strobe" (see DEFINE OUTPUTS - DEFINE 
INT/STRB in par. 4.8). 
The +12V and "GND" terminals can be connected to a 
siren (for constant DC power supply) – not 
applicable in North America.  
WARNING!
 When an Internal GSM module is connected, 
the CELL/PC port of the Dual RS-232 module cannot be 
used for PC connection. In this case, either remove the 
Internal GSM or use the PL/PC connector. 
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. 
3.5.3 Installing an Optional X-10 Siren 
If you need a “wireless” external siren, you may install an 
X-10 siren module which is triggered by a signal transmitted 
via the built-in electrical wiring of the protected site. This 
siren can replace the regular external siren or complement 
it without laying out additional wires. Of course, such a siren 
can be used only in conjunction with an optional power-line 
interface module.  
The X-10 siren is ready to function upon connection to an 
electrical power outlet, without re-programming the 
PowerMax Pro. You only have to set the HOUSE CODE 
and the UNIT CODE selectors on the X-10 siren as follows: 
House Code: Set this selector to the letter that follows, by 
alphabetical order, the letter that you programmed as a 
house code for the protected premises. For example, if the 
programmed house code is “J”, set the siren house code 
selector to “K”. 
Note: If the programmed house code letter is “P” (which is 
the last programmable letter), select “A” for the siren. 
Unit Code: The siren will function only if you set the unit 
code selector to “1”.
