General Description:
The Model SD4-MC photocell electronic smoke detector with built-
in wireless transmitter is intended for use with the Silent Call® Mini
receiver to form an alerting system. The transmitter will send alarm
condition messages to the system’s receiver.
The SD4-MC wireless transmitter operation is to be used only with
Silent Call® Medallion Series Receivers. The transmitted signal incor-
porates a Million Code Address principle that provides each SD4-MC
detector with a unique one in a million address. This helps to keep
any cross talk between like transmitters in a typical single living,
multi-dwelling, or apartment building to a minimum where it is possible
to have adjacent apartments with Medallion Series Receivers.
IMPORTANT: The range and proper operation of any wireless device
will vary depending on its surroundings. It is very important that each
SD4-MC detector is tested with each receiver intended for Alarm.
The Model SD4-MC incorporates a state of the art optical sensing cham-
ber and an advanced microprocessor. The microprocessor allows the
detector to automatically maintain proper operation at factory calibrated
detection levels, even when sensitivity is altered due to the presence
of contaminants settling into the unit’s smoke chamber. In order for
this feature to work properly, the chamber must never be opened while
power is applied to the smoke detector.
