EMI (Electro Magnetic Interference)

AC wiring can induce EMI (both noise and low level voltage)
into adjacent wiring. Run phone and sensor loop wiring away
from AC conductors, including the transformer wire. Run
keypad wiring away from AC and phone wiring.

EMI may also occur if you install the panel or run system
wires near the following:

• Computer network systems
• Fluorescent fixtures
• Telephone cabling
• Ham radio transmitter sites
• Heavy machinery and motors
• High voltage electrical equipment
• PBX telephone systems
• Public services (police, fire departments, etc.) using

radio communications

• Radio station transmitter sites, or other broadcast

station equipment

• Welding shops

If EMI may be a problem, use shielded cable. The drain wire
for the shielded cable must have continuity from terminal 3,
earth ground on the panel, to the end of the wire run.

If continuity is not maintained, the shielded cable may
aggravate potential noise problems rather than eliminate
them. If you cut the drain wire to install devices, be certain to
splice it together. Solder and tape all splices.

Connecting the drain wire to ground at a location other than
terminal 3 may also produce problems.

Connect Earth Ground

Terminal 3

To help prevent damage from electrostatic charges or other
transient electrical surges, connect the panel to earth ground
at terminal 3 before making any other connections. A
grounding rod or cold water pipe are recommended earth
ground references.

Radionics does not recommend a telephone or electrical
ground for the earth ground connection. Use 18 AWG wire
maximum under the terminal. Use a spade lug or splice for
larger wire.

Do not connect any other panel terminals to earth ground.
The panel’s common terminals and terminal 3, earth ground,
are electrically isolated.

Transformer

Terminals 1 and 2

Connect the transformer to terminals 1 and 2 on the panel
before plugging it into the power source.

Use 18 AWG wire to connect the transformer to the panel.
Wire length should be kept as short as possible. Maximum
length is 50 feet.

Never share the transformer with other equipment:
Foreign grounds on the AC input damage the panel's power
circuit.

Battery

Terminals 4 and 5

Place the battery upright in the base of the enclosure. First
connect the stripped end of the black battery lead to terminal
5 on the panel. Then plug the other end to the negative (-)
side of the battery.

Next connect the stripped end of the red battery lead to
terminal 4 on the panel. Then plug the other end to the
positive (+) side of the battery.

Charge the Battery as You Work

Lock the Standby Switch

Locking the pin in the closed/standby position allows you to
charge the battery as you install the detection devices and
keypads. Lock the pin down now. See Figure 2.

With the Standby Switch locked down, the panel deactivates
the external relay outputs, suppresses reports, and disables
all arming functions.

Lock the Standby Switch down to program the panel
locally, from the keypad, or the D5200.

Releasing the Standby Switch from the closed position
resets the panel. The panel resets all its timers and counters,
and clears all buffers. If the panel is armed, releasing the
standby switch causes the panel to disarm.
