for the RF3405E
Wireless (RF) Inertia T ransmitter
1.0 General Information
The RF3405E Inertia Transmitter is a magnetic and dry
contact wireless transmitter with a built-in inertia sensor
used for monitoring doors, windows, or other dry
contact devices.
The inertia transmitter is equipped with internal reed
contacts for use with an external magnet assembly and
an inertia sensor for detecting shock. The transmitter
can also accept a dual EOL resistor supervised dry
contact input from an external device. A cover/wall
tamper switch is provided.
Supervision is provided by periodically transmitting a
supervisory signal to the receiver every 13 minutes if
there is no other activity. All transmissions from the
RF3405E send battery status information.

• The maximum range of the inertia transmitter, in
open air, is approximately 300 m (98 ft.).
Typically, keep this transmitter within 100 m
(328 ft.) of the receiver to which it is assigned.
• Mounting the inertias transmitter on metal
surfaces may reduce its RF range. Mounting it on
ferrous metal (iron or steel) surfaces may affect
the operation of the internal magnetic contact.
• Mount the inertia transmitter on the door or
window frame and mount the magnet assembly
on the moving portion.
The magnet assembly must be oriented as
shown in
Figure 1
. The magnet must be no
farther away than 10 mm (0.39 in.) from the
body of the inertia sensor for normal
operation.

4. Mount the base plate using the 13 mm (0.51 in.)
panhead screws (callout #3) through the base

5. Refer to Section 2.4 Mounting the Inertia Sensor if the
inertial sensor is used.

Orientation of the Inertia sensor is critical to
the proper operation of the inertia detection
function.
An UP arrow, imprinted on the body of this
sensor, must always point upwards when
mounted in the transmitter base.

2.4 Mounting the Inertia Sensor
1. Mount the inertia sensor so the wires are over the
notched portion of the base plate (see Figure 4).
2. Press the inertia sensor all the way into the bracket.
3. You can mount the inertia sensor in four different
positions on the base plate (see Figure 5). Route the
wiring in a way that prevents crimping by the cover.
