USEFUL HINTS FOR POWERMAX USERS 
Stopping an alarm:  When the alarm sounds - press the DISARM (
) button on your key-ring transmitter or press
on the keypad and then enter your access code (1 1 1 1 by default). 
Stopping trouble beeps: When trouble occurs in the system, the TROUBLE indicator on the front panel will light, and 
a sequence of 3 beeps will sound once per minute. If you do not wish to eliminate the trouble immediately and the beeps 
are bothersome, press the DISARM ( ) button on your key-ring transmitter, or press
on the keypad and then 
enter your access code (1 1 1 1 by default). This will silence the buzzer for 4 hours, after which the trouble beeps will 
resume sounding. Be advised, however, that in any case the trouble beeps are silenced during night hours. 
Perimeter and interior zones versus 24-hour zones: Most of the protection sensors in your system are linked to 
perimeter and interior zones. These zones trigger alarms while the system is in the armed state and do not trigger 
alarms while the system is in the disarmed  state. Other sensors are linked to 24-hour zones which trigger alarms 
irrespective of arming/disarming.  
Arming while perimeter zones are not secured (doors and/or windows are open): Your display will read 
“NOT READY” if a protected door or window is open. You can find out which zone is “not ready” by clicking the 
<SHOW/OK> button. You can eliminate the problem by closing the door/window. If you choose not to do so, check with 
your installer whether he has permitted automatic bypass (deactivation) of any zone that is not secured upon termination 
of the exit delay (a voice message will announce that ”Forced Arming” is under way). Bypassed zones will not be 
protected throughout the arming period. 
Conversely, if you want to bypass a zone intentionally, leave the door or window open and arm the system (a voice 
message will announce that ”Forced Arming” is under way). 
Gaining access to 24-hour zones: If you wish to access a sensor defined as a 24-hour zone without causing an alarm: 
 Click <NEXT> - the display will read: NORMAL MODE. 
 Click <NEXT> again - the display will read: USER SETTINGS. 
 Click <SHOW/OK> - the display will read: ENTER CODE ___. 
 Key your secret 4-digit <User Code> - the buzzer will play the “happy tune” (- - - ––––). 
You have 4 minutes during which the 24-hour sensor can be opened and accessed. When the 4 minutes are up, the 
system will automatically revert to the normal mode. 
Canceling accidental alarms: Upon alarm, the internal sounder is activated first for a limited period of time (set by 
the installer). Then the external siren starts and the event is reported to the central monitoring station. If you accidentally 
cause an alarm, you may simply disarm the system before the external siren starts - the alarm will not be reported. 
If you cause an alarm accidentally and the external siren has already started - you can still disarm the system within a 
time limit set by the installer (1 to 15 minutes, as desired). If you manage to disarm on time, a CANCEL ALARM message 
will be automatically sent to the central monitoring station. 
Failing to exit before the exit delay expires: If you exit the protected site after the exit delay expires (the exit 
delay beeps stop), the system will interpret this as if you just entered. The entry delay countdown will begin and the entry 
delay beeps will sound. To prevent an alarm, you must disarm the system before the entry delay expires. 
Unauthorized entry took place while you were away: If you hear alarm sirens when you are about to re-enter 
the premises, and lights which should be off are on - an intruder may still be inside or another event may have occurred. 
Do not confront the intruder - remain outside and call the emergency services.
