XL-20 Hookup and Installation Instructions
Reset
After an alarm occurs, the system enters Alarm Memory mode either after Bell timeout or by
a user entering a valid user code silencing the bell and keypad buzzer. Alarm memory and
communications failure can be cleared by entering a valid User code. If a fire alarm
occurs, then clearing Alarm Memory resets the smoke detectors for approximately 8 seconds.
In addition, you can use the * key to act as a fire reset. This option is
programmable in question 05, location 3.
Bypass
Bypassing is performed to temporarily exclude zones that are faulty or not ready from
activating the system.
If Quick Bypass is not enabled, then press the BYPASS button followed by any
valid 4-digit user code, followed a number from 1 to 6, which represents the zone to
be bypassed.
Subsequent bypasses can be made by pressing the BYPASS button and then pressing
another zone number within a 10-second period. After this 10-second period, the entire
command - including the user code - must be entered.
After a successful bypass, the keypad sounder will sound the acknowledge beep, and the
respective zone LED will WINK SLOWLY.
The bypass rules are:
• FIRE zones cannot be bypassed
• 24-hour zones can be bypassed; however, they CANNOT be unbypassed if they are
violated.
• Zones can only be bypassed while the system is disarmed, at which time visual indication
will be displayed.
• Bypass signals are transmitted to the central station UPON ARMING if a Bypass code has
been programmed.
Zones that are bypassed are not protected when the system is armed.
Quick Bypass
Quick Bypass is a programmable option (see question 05, location 3 of the programming
sequence) and allows the user to bypass zones without using a User code.
Press the BYPASS button followed by a number from 1 to 6, which represents the
zone to be bypassed.
Auto Unbypass
All burglary zones which are bypassed can be automatically unbypassed upon
system disarm, assuming no other zone(s) were in alarm. 24-hour zones that have
been bypassed will be unbypassed only if they are normal.
6–2
