A Profile of a Security Industry Leader
Linear LLC offers a full spectrum of advanced alarm monitoring components,
on a worldwide basis, for the residential and commercial security
market. It has been designing and building for this market
for over 50 years and is regarded as one of the founders and
leaders of the contemporary security industry.
The company has a well-earned reputation in the radio frequency (RF) or
“wireless” approach to alarm signal transmission,
and is acknowledged as having the greatest concentration of
RF engineering experience and talent in the security products
field.
Linear products are available throughout the world through a worldwide
network of more than three hundred security distributor locations.
Key Contributions to the Security Industry
- Introduced the first RF link for use in the security industry.
- Introduced the first digital RF link for use in the security industry. (Standard Digital)
- Instrumental in the development of the digital communicator via our SESCOA division.
- Inventor of the PIR based security lighting product.
- One of the first companies to offer a Personal Emergency Reporting System to the industry for transmission
of an emergency condition.
- Developed and introduced the first supervised RF link for use in the security industry. (S1 format)
- Developed and introduced the first multi-million code transmission format to the security industry. (MegaCode)
Today, Linear combines the techniques of passive infrared detection,
radio frequency transmission and reception, digital electronics
and human engineering to produce highly functional, highly
reliable security products. The company’s model offerings
number in the hundreds, and range from simple transmitter/receiver
links for use in just about any application imaginable to
totally supervised RF based security systems for low, medium
and high-end applications. The Linear line of RF based products
and accessories are the most extensive in the industry.
Security products bearing the Linear name are installed residentially
and commercially throughout the United States of America and
around the world. Many of these installations occur in prominent
and prestigious facilities, further attesting to product quality
and reliability. In addition to security products, Linear uses its extensive
RF expertise in an active original equipment manufacturer
(OEM) program. This design, engineering, and manufacturing
activity not only includes alarm-related applications, but
also innovative uses for remote sensing and remote control
functions outside the security industry. Spa, lighting and
sprinkler control are just a few of the applications where
Linear’s RF expertise has been used as a value added
feature.
Distributors
Linear products go to market on several paths. As indicated, there
is a worldwide organization of more than 300 distributors
who actively stock and sell the product. Added to this group
are a select number of alarm system installation companies
and central station operators. Retail home centers offer specific
Linear security products on a private label basis to their
do-it-yourself customer base.

The company maintains its executive staff, sales, engineering, and research
and development resources in Carlsbad, California. Primary
manufacturing is performed in our China facility. Linear also

Linear Training
 Technical Services is the group within Linear LLC that administers Continuing Education Unit (CEU) activities, courses, and programs. Technical training ensures the education and meets the goals of the dealers, distributors, and others who sell the Linear LLC branded products.
The technical training manager reviews the policies and procedures and ensures they meet accreditation requirements for CEUs. Linear LLC accredits their training through the National Burglar & Fire Alarm Association (NBFAA) service of the National Training School. The review process for every program occurs every two years at a minimum.
Linear will ensure the training provides adequate resources to support a positive learning environment. Instructors will be available to provide assistance and support to students.
When students meet the requirements for satisfactory completion of the training program, they are issued a certificate that indicates the title of the program, the name of the instructor, and the number of CEUs for the program. Training in Texas will result in an additional form with the instructors' numbers annotated for state requirements.
Linear maintains the records for approximately one year and can reissue certificates if desired. Information collected during training is only for the use of documenting students attending class and is not sold, released, or transferred for any other purposes.
Linear training is provided by qualified personnel with many years of experience in the field and competence in their topic of instruction.
