Congratulations on your purchase of a quality Silencer security system. Your new Silencer security system
has been designed to provide years of trouble free service when operated and maintained in the manner set
forth in this manual. Your full knowledge of the features provided by your security system and their methods
of operation are essential for day-to-day usage. Please take a moment to read through this manual and
become familiar with the features that pertain to your security system. Located at the back of this booklet, we
have provided a listing of all the upgrade features available for your security system. Additional installed
features vary by dealership, but any can be added at a later date. Contact your new car dealership for details.
The Model Number of your Silencer Security System is 7921P
The basic function of this system is to provide an upgraded level of security to an existing manufacture
installed keyless entry system or security device. The 7921P can also be used as a stand alone Silencer
remote keyless entry and security system or a “remoteless” passive arm security system. Please read
and follow the procedures enclosed to operate your system.
Determine the Control Device
Your Silencer 7921P can be controlled from a variety of different devices. Determine which device is
controlling your system and proceed to that section of this manual. In some cases, the 7921P will have 3
different controllers. Read the information pertains to all controllers.
System Control by the Factory Keyless Entry Transmitter (Basic Operation)
If the vehicle you purchased came with remote keyless entry transmitters, two of the buttons on the
transmitter will be used to lock and unlock your vehicle. These buttons will have the words “LOCK” and
“UNLOCK” printed or engraved on them or they will have pictures of a padlock in a locked and unlocked
position (see illustration at above). Use the lock and unlock buttons on the transmitter to control your new
Silencer security system in the following manner.
Manual Arming and Disarming
1. Exit the vehicle and close all of the entrances.
Note: After closing the last protected entrance, you will hear the siren or horn chirp. The reason for this
chirp is covered below in the “Automatic Arming” section of the manual. Proceed as follows:
2. Press the LOCK button on your keyless entry transmitter. Your Silencer Security system will respond in
the following manner:
A. The siren or vehicle horn will emit a single chirp*.
B. The parking lights may flash one time.
C. The LED indicator for the security system will start to flash.
The system is now armed.
3. Press the UNLOCK button on your keyless entry transmitter. Your Silencer security system will respond
in the following manner:
A. The siren or vehicle horn will emit 2 chirps*.
B. The parking lights may flash two times.
C. The LED indicator for the security system will start flashing fast indicating that the system will rearm in
60 seconds. (Opening the driver’s door or turning on the ignition key will momentarily stop the auto
arming feature.)
The system is now disarmed.
