INSTALLATION GUIDE 

Indoor siren self-powered 

Version 1 

Made in France 

SI-MAX 

 

SI-MAX

 is an indoor siren… 

VERY POWERFUL!

 

In discrete metal box, self-protected against forced opening and tear with 
housing for the internal battery 12V – 2Ah, SI-MAX is the inevitable solution to 
deter intruders. 
 
The terminal « +12V CHARGE »is used for constant load from the battery’s internal siren. 
 

SI-MAX

 offers a 

double load regulation

 for battery: 

Regulating the load current to 100 mA

, sufficient to charge the internal battery 

normally. 

In alarm only the internal battery is required. This effectively protects 

the charger from the panel when multiple sirens are powered by it.

 

Regulation of the charging voltage to 13,8 Vdc : 

even if the charging voltage 

delivered by the panel is not high enough, SI-MAX amplifies it to provide the battery with 
a charging voltage maximum of 13.8 Vdc to warranty a perfect load.  

 

SI-MAX has a tamper against the forced opening and tear

 without any regulation. The tamper 

against the forced opening can function only by adding a screw on top of the card (length of the 
screw 55-65mm, diameter: 4 to 5mm). The screw is placed just above the electronic card. It must 
be screwed into the wall until its head comes into contact with the electronic circuit without 
pushing on it. To facilitate the positioning of the screw, use the drilling template provided.  

_________________________________________________ 

OPERATION 

A positive and continuous voltage of 9 to 16V on the terminal "+ BL SIR" can block or reset the 
SI-MAX. At the disappearance of this blocking voltage, the alarm is activated for duration of 31 
minutes. At the end of this delay, the SI-MAX is on standby, which avoids damaging the internal 
battery by a complete discharge. 

 

To trigger again, SI-MAX must be reset: the blocking voltage of 9 to 16V should reappear on the 
terminal « +BL SIR» for at least 1 second. 

 

Note that during the power up, SI-MAX doesn’t trigger even if the blocking voltage is absent. It 
must first be arm by applying the blocking signal for at least 1 second. 

 

Moreover, the supply being provided by the terminal « +12V CHARGE» which limits the current to 
100mA, SI-MAX can trigger only in the presence of the internal battery 12V-2Ah.
