INSTALLATION
The receiver should be mounted on the wall above or next
to the control panel. Generally, the higher the receiver is
mounted above ground level, the better the radio range
should be.
Use Table 1 as a guide and follow these steps to connect
the receiver:
STEP 1 Connect receiver negative COMMON (-) to the
negative terminal on the 12-volt, 24-hour output
from the control panel.
STEP 2 Connect receiver positive (+) to the positive
terminal on the 12-volt, 24-hour output from the
control panel.
STEP 3 Connect the outputs to the zone input terminals
on the control panel (see Figures 1, 2, and 3).
STEP 4 If the control panel uses end-of-line resistors,
connect them across the receiver output for
normally open loops, or in series with the receiver
outputs for normally closed loops.
CHECKOUT AND TEST
After installing the receiver, the system should be tested.
To test the receiver, perform the following steps:
STEP 1 Apply power to the control panel. Be sure the
control panel is disarmed or in a “test” mode.
STEP 2 Trigger each of the system’s transmitters, one at
a time. Receiver activation indicates that the
transmitters are operating properly and that the
digital codes are correctly matched. Verify that
the correct receiver channel and control panel
loop is violated.
STEP 3 With portable transmitters, operate them from
various locations. This will help to locate possible
null areas where structural steel, and/or certain
obstacles may interfere with transmission.
If the transmitter fails to activate the receiver, first check
the coding switches to see that the switch keys in the
transmitter and receiver are properly matched. Next, check
the battery and replace it if it is weak. Although transmitter
batteries should last for a year with normal use, it is good
practice to install new transmitter batteries every six
months.
✶
Electronic products are no better than the inspection and
maintenance they receive over time. Therefore, Linear
recommends installers should instruct their customers to
test their equipment regularly, at least once a week.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill an
important need in portable wireless signalling. However, there are some
limitations which must be observed.
☞
For U.S. installations only: The radios are required to comply with FCC
Rules and Regulations as Part 15 devices. As such, they have limited
transmitter power and therefore limited range.
☞
Receivers may be blocked by radio signals that occur on or near their
operating frequencies, regardless of code settings.
☞
A receiver cannot respond to more than one transmitted signal at a
time.
☞
Infrequently used radio links should be tested regularly to protect
against undetected interference or fault.
☞
A general knowledge of radio and its vagaries should be gained prior
to acting as a wholesale distributor or dealer, and these facts should
be communicated to the ultimate users.
