General:
The Mini Receiver is a 418 MHz wireless alerting device equipped
with 24 hour battery backup. Main Power is supplied using a
Silent Call 18 watt AC/DC Wall mount Adapter P/N 890007-2. The
Mini Medallion Series Receiver can store up to 20 from a possi-
ble one million, Silent Call 418 MHz Medallion Series transmitter
address codes.
Installation:
Installing the Mini Receiver consists of locating it where it can be
noticed most effectively by the user. Plug the AC/DC wall mount
adapter into any standard household 110VAC 60Hz outlet. Insert
the adapters DC barrel plug into the Mini Receiver Barrel Jack
Labeled “Power”. Slide the power switch to the ON position and
confirm the Power ON GREEN LED is illuminated under the top
strobe lens. The receiver is now ready to be programmed.
Programming:

grammed to your new receiver.The receiver leaves the
factory with the memory cleared.
Apply power to the receiver as described in the Installation sec-
tion.
With the receiver powered, press and hold the program button
located at the back of the receiver case. All display icons will illu-
minate. Continue to hold the program button until the icons goes
out (about 3 seconds) and then the GREEN PHONE icon blinks 3
times. Release the program button. The receiver display icons
will come back on to indicate that the receiver is now in program
mode. The receiver will remain in program mode for approxi-
mately 30 seconds, and the display icons will start to go out to
indicate the program time remaining. While in program mode,
the transmitter you wish to program must be activated (Trans-

mitting) for the receiver to memorize the code of the transmitter.
The transmitter can be activated by pressing the test button on
the corresponding transmitter. When the receiver receives the
transmitted signal, it will memorize the code. The receiver should
activate and flash the top strobe light, and the appropriate display
icon will illuminate.
Programmed transmitter codes are retained in memory even
when the power is removed.

will come on for about 3 seconds, go off and then the GREEN
PHONE icon will blink 3 times. Continue to hold the program
button an additional 3 seconds until the icons scroll in a counter-
clockwise direction several times indicating all previous learned
transmitters that were stored in memory have been erased.
Release the program button and all previously learned transmitter
codes will have been successfully erased.
Battery Backup Mode:
In the event of a main power loss or failure of the wall adapter,
the Mini Receiver will automatically enter into the battery backup
mode. The Mini Receiver has been tested to provide at least 24
Hours of Battery backup operation with 15 minutes of Alerts.
Located under the top strobe lens cover is an AMBER LED. The
AMBER LED will blink once every 10 seconds, indicating Input
DC power loss to the receiver and it is operating on the back-up
battery. The AMBER LED will blink at a one second rate once the
back-up battery has reached minimum operating voltage. Operat-
ing the receiver during a low battery indication is not recommend-
ed.
IMPORTANT: The Mini Receiver will need to charge two hours for
every hour in Battery backup mode or a full 40 Hours after low
battery indication to ensure complete battery recharge.

Mini Receiver operating on Main power and the amber LED is ON
or blinks, indicates a failure of the unit. Return the MR1214-MC
with AC/DC adapter to the manufacturer for repair.

LED Intensity Selection:
Located on the back of the receiver at the top is a switch that
will allow the user to select the brightness, or the Intensity of the
LED’s. LED intensity High, Medium, and Low selections are avail-
able. When making the selection of the LED brightness make sure
the LED strobe is off and the receiver is not processing a received
alert.
It is recommended by the National Fire Protection Agency that
when this unit is used for a fire indication to use the high setting.
Operation:
When the Mini Receiver detects a signal from a Silent Call Medal-
lion Series pre-programmed transmitter, it illuminates the corre-
sponding indicator icon and activates its built-in High Intensity
LED strobe light. The indication will continue for approximately
16 seconds after the transmitted signal ceases. As long as the
Medallion Series Smoke Detector, Fire Alarm Transmitter, or CO

Detector continues to send an alert signal, the Mini Receiver alert-
ing mechanisms will remain on. The Mini Receiver has a Coded vi-
brator output for use with the Silent Call Bed Vibrator P/N VIB-PJ.
Optional Bed Vibrator Auxiliary Output:
Located on the rear of the Mini Receiver is an auxiliary output jack
labelled “Vibrator” for interfacing Silent Call VIB-PJ bed vibrator.
See the chart below for the vibration pulse pattern. The pattern
repeats during the 16 second receiver cycle.
