The SF202B is a self-contained alarm unit suitable for single or
multi-family residential buildings. It provides for connection of
selection devices to signal intrusion through doors or windows or
to signal fire, smoke, medical or other emergency conditions.
Intruder Alarm: The intruder alarm is armed by pressing a
single button on the unit and selecting either the IN or OUT mode.
As an aid to prevent false alarms, the unit cannot be armed unless
the protected door and windows are closed.
In the IN mode, the unit is ready for instant operation when armed.
In the OUT mode a 40-second delay permits exiting. When
returning, a 25-second delay allows the occupant time to disarm
the unit, during which time a pre-alarm is heard as a reminder.
The unit is disarmed by entering a private four-digit code on the
keypad. If unit is not disarmed a loud pulsating tone will be heard
on the premises and may be transmitted to external alarm signal-
ing devices. The alarm will continue for five minutes, unless
disarmed, and then will stop. A flashing light on the unit will
continue to signal that an intrusion occurred.
Panic Alarm: The panic alarm is operated by pressing buttons 2/
7 and 4/9 on the unit simultaneously or by pressing any panic
buttons that may be transmitted to external devices if connected.
The panic alarm will continue until reset by entering the four digit
External Alarm: An output is provided to operate annunciator
panels and similar devices. External reset is provided to permit
service or to permit connecting two units in the same residence for
greater convenience and security.
