General Information
Before installing detectors, please thoroughly read these installation
instructions. For detailed information on detector spacing, placement,
zoning, wiring, and special applications refer to current edition of the
NFPA 72 National Fire Alarm Signaling Code.
NOTICE: Do not discard this manual. Manual should be left with the
owner/user of this equipment.
IMPORTANT: This detector must be tested and maintained regularly fol-
lowing NFPA requirements. Test detector operation weekly. The detec-
tor should be cleaned at least once a year.
NOTE: Smoke Detectors have a limited life. Smoke detectors should
be replaced immediately if not operating properly. You should always
replace a smoke detector after 10 years from date of purchase.
NOTE: Remove battery tab before installation.
NOTE: Radio Frequency device operates at 418MHz
FCC ID: PPJSD4418SC
General Description:
The Model SD4-MC(US) 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(US) wireless transmitter operation is to be used only
with Silent Call® Medallion Series Receivers. The transmitted signal
incorporates a Million Code Address principle that provides each SD4-
MC(US) 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(US) detector is tested with each receiver intended for Alarm.
The Model SD4-MC(US) incorporates a state of the art optical sensing
chamber and an advanced microprocessor. The microprocessor allows
the detector to automatically maintain proper operation at factory cali-
brated detection levels, even when sensitivity is altered due to the pres-
ence 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.
This includes cleaning, maintenance or screen replacement.
The Model SD4-MC(US) contains a piezoelectric horn which generates
the ANSI S3.41 temporal pattern in an alarm condition. During an alarm
condition, pressing the detector’s test switch will silence the piezo-
electric horn for 5 minutes. The built-in Drift Compensation algorithm
automatically maintains the sensitivity of the detector. The mounting
base installation is simplified by the incorporation of features compat-
ible with drywall fasteners or other methods that provide a method for
securing the detector in place.
Current studies have shown smoke detectors may not awaken all
sleeping individuals, and that it is the responsibility of individuals in the
household that are capable of assisting others to provide assistance to
those who may not be awakened by the alarm sound, or those who may
be incapable of safely evacuating the area unassisted.
Two LEDs and a sounder on the detector provide local visual and audi-
ble indication of the detector’s status:

Power-up
Table 1: Detector LED Modes
During initial power-up, the red and green LEDs will blink synchronous-
ly once every 5 seconds. It will take approximately 20 seconds for the
detector to finish the power-up cycle (see Table 1).
After the power-up cycle has been completed and the detector is
functioning normally within its listed sensitivity range, the green LED
blinks once every 10 seconds. If the detector is in need of maintenance
because its sensitivity has shifted outside the listed limits, the red LED
blinks once every 5 seconds. When the alarm has been activated by
smoke, the red LED blinks every 1 second. The LED indication must
not be used in place of the tests specified under Testing. If the detector
senses a low battery condition, the red LED blinks once every 45 sec-
onds.
Low Battery Detection:
The Model SD4-MC(US) is powered by a single 3-volt CR123A Lithium
battery. The detector checks for a low battery at least every 65 minutes.
In addition, the red LED of the Model SD4-MC(US) will blink every 45
seconds and the test switch will be disabled. This condition will exist for
a minimum of 7 days, and then the detector’s horn will “chirp” about
every 45 seconds. Pressing the test switch during this time will silence
the chirps for 12 hours. The battery should be replaced BEFORE the
chirps begin. Be sure to replace the battery with a fresh one. Batteries
can be purchased directly from Silent Call Communications by calling
1-800-572-5227, or online at www.silentcall.com.
Battery Life Expectancy:
Replace the battery once a year or immediately when the low battery
indicator starts to blink and the horn begins to chirp.
Battery Installation and Replacement:
To replace the battery:
1. Remove the detector from its mounting base by twisting the detec-
tor counterclockwise. Remove the battery and dispose of it
properly.
2. To ensure proper power-down sequence, wait a minimum of 20
seconds before installing new battery.
3. Install a new approved 3-volt Lithium battery in the battery com-
partment. Follow the polarity diagram inside the compartment.
4. Reinstall the smoke detector onto the mounting base by turning
the detector clockwise.
5. The green LED should blink about once every 10 seconds to indicate
normal operation. If the battery is not installed correctly, the smoke
detector will not operate and the battery may be damaged. If the
detector does not appear to be sending a signal during any of the
tests, check for correct battery installation and for a fully charged
battery.
6. Test Smoke detector operation with Medallion Series Receiver to
verify proper operation.
NFPA Required Protection:
This smoke detector should be installed in accordance with the Nation-
al Fire Protection Association, Standard 72 (National Fire Protection
Association, Quincy, MA 002269). This detector will provide maximum
protection when installed in compliance with the National Fire Protec-
tion Association (NFPA). Standard NFPA 72, household fire warning
equipment
“For your Information, the National Fire Alarm and Signaling Code
NFPA reads as follows”
11.5.1* Required Detection
Where required by applicable laws, codes, or standards for a specific
type of occupancy, approved single and multiple-station smoke alarms
shall be installed as follows:
1. *In all Sleeping Rooms and Quest Rooms.
2. *Outside of each separate dwelling unit sleeping area, within 6.4 m
(21 ft) of any door to a sleeping room, with the distance measured
along a path of travel.
3. On every level of a dwelling unit, including basements.
4. On every level of a residential board and care occupancy(small fa-
cility), including basements and excluding crawl spaces and unfin-
ished attics.

Recommended Locations for Smoke Detectors:
The National Fire Protection Agency (NFPA) recommends one smoke
detector on every floor, in every sleeping area, and in every bedroom. In
new construction, the smoke detectors must be AC powered and inter-
connected. For additional coverage, it is recommended that you install
a smoke detector in all rooms, halls, storage areas, finished attics, and
basements where temperatures normally remain between 4.4°C to
37.8°C. Make sure no door or other obstruction could keep smoke from
reaching detectors.
Specifically locate detectors:
• On every level of your residence, including basements and finished
attics.
• Inside every Bedroom, especially if people sleep with the doors
closed.
• Inside every bedroom where electrical appliances (such as portable
heaters or humidifiers) are operated where someone sleeps.
• At the bottom of the basement stairwell.
• At the top of the first-to-second floor stairwell, as long as no other
door or other obstructions block the path of smoke to the detector
• As close to the center of the ceiling as possible. If this is not practi-
cal, put the detector on the ceiling, but no closer than 4 inches (10
cm) from any wall or corner. See figure 1.
• If wall mounting is permitted by your local and state codes. Put the
top of wall-mounted detectors between 4 and 6 inches (10 and 15
