3. Installation Recommendations

The SA-02N Magnetic Contact Sensor detects the opening and closing
of doors and windows, and transmits this information to the receiver
panel.

 AVOID placing the Magnetic Contact Sensor near strong magnetic

or electrical fields other than the magnet with which it is intended
to be used; otherwise, performance may be affected and false
alarms may occur.

 AVOID mounting on or near large metal surfaces and multiple

concrete/steel walls, as this may interfere or block the wireless
signals. Make sure to test the range from any location by using the
RF Test Procedure to ensure reception.

Install the magnetic contact sensor on windows or doors that
have firm hinges and firm locking action to prevent false
alarms associated with wind or bumping.

4. Installation Instructions

4.1 Selecting the Location

The location and mounting of the SA-02N affects both the
transmission range and the wear and tear of the transmitter. Preferably
the transmitter should be installed as close as possible to the receiver,
and mounted in a high location so that the transmission has less
interference.

To select the location:

1. Select a door or window within a room or hallway that best
matches the criteria in Section 3 (see Figure 2).

2. Make sure that the Magnetic Contact Sensor is mounted on a
sturdy, non-vibrating door or window frame.

Following this instruction reduces bumping and vibration
effects on the sensor and extends the life of the product.

3. Perform the RF Test from the proposed mounting location to
ensure that the sensor can be received.

4. Select the appropriate height for the magnet assembly that suits
the location of the sensor.

Figure 2: Selecting a Location

4.2 Selecting the Magnet Height

The SA-02N comes equipped with a standard magnet of adjustable
height, suitable for most applications (Figure 3).

Figure 3: Magnet

When there is a mismatch in height between the door and the frame,
simply press on the sides of the mechanism on the magnet to adjust
the height of the magnet assembly to suit the location of the sensor.

4.3 Installing the Battery

Use only a 3.6 V Lithium battery (see battery specifications in Section

2.1).

To install the battery:

1. Unscrew the case locking screw and remove the front cover. You
can now see the front of the PCB (Figure 4).

Figure 4: PCB Layout

Do not touch the magnetic element or the electronic
components inside, as doing so may cause damage.

2. For a new unit, simply remove the plastic strip contact breaker. For
replacement, remove the battery using a small screwdriver.

3. Install the new batteries in the correct alignment. The polarity of
each battery (+) and (-) must coincide with the markings (+) and (-)
on the plastic.

Dispose of the old battery properly. Do not recharge,
disassemble, heat, or incinerate.

4. To test, depress both the back tamper and the case tamper
buttons, or use a magnet to simulate a door opening and closing.
The LED lights up to indicate RF transmission.

5. Close the front cover and replace the locking screw.

4.4 Activating the Back Tamper

Each SA-02N Magnetic Contact Sensor is equipped with both a back
and case tamper detector. The case tamper detector is always active;
however, the wall (back) tamper detector (normally inactive) can be
optionally activated for additional protection against the theft or
removal of the sensor from the mounting location.

The back tamper can be activated to work in unison with the case
tamper by cutting the JP1 jumper, which is on the top side of the PCB.

To activate the tamper:

1. Remove the case locking screw and front cover.

2. Cut the JP1 jumper to activate the back tamper switch (Figure 4).

3. Replace the front cover and locking screw.

4.5 Wiring the External Sensor

When an additional set of contacts is needed for the SA-02N, it is
possible to tie them together with those of the SA-02N to save having
an extra transmitter. In addition, the external magnetic sensor must be
connected in series with the internal SA-02N magnetic sensor so they
both occupy the same zone.

The maximum distance between the external contact and the
SA-02N is about 8.5 meters or 25 feet.

To wire the external sensor:

1. Remove the case locking screw and front cover.

2. Remove the jumper located below the terminal block pins (Figure

4).

3. Connect the external magnet(s) in series to the wired input
terminal block of the magnetic contact sensor.

4. Replace the front cover and locking screw.

4.6 Mounting the Magnetic Contact Sensor

The SA-02N Magnetic Contact Sensor is designed to be mounted onto
a flat wooden or stucco surface.

When mounting the SA- 02N to the surface, it is important to
see that the surface is flush with the back tamper device.

To mount the sensor:

1. Remove the PCB from the back case.

2. Remove the knockouts from the back case labeled B, by using a
sharp tool or using a nail (Figure 5).

Figure 5: Mounting the SA-02N

3. Affix the two screws onto the wall, so that the back tamper arm is
pressed in.

4. Replace the PCB and tighten the PCB locking screw.

5. Replace the top cover of the magnetic contact sensor.

If the back tam per has been activated in previous steps, check

the security panel to ensure that there is no tamper signal, and

that the sensor is properly installed.

4.7 Performing Radio Transmission Test

This test is used to check the range and reception of the sensor to the
control panel receiver. If reception is poor, try to change the location of
the Magnetic Contact Sensor.

To perform a radio transmission test:

1. Ensure that all the settings of the Magnetic Contact Sensor are
adjusted as necessary for the location and that the Magnetic
Contact Sensor case is closed, with the locking screw firmly
secured.

2. Hold the sensor as close as possible to the mounting location, and
transmit using the magnet.

3. During this mode, each time the LED flashes, the sensor transmits
to the panel. If the panel is armed, an alarm is activated. If the
panel is in Test mode, the signal strength can be measured.

4. It is recommended to try several locations until the best reception
is attained.

4.8 Replacing the Battery in the SA-02N

Batteries in the SA-02N should be replaced following a Low Battery
indication on the receiver or security panel.

Dispose of the old battery properly. Do not recharge,
disassemble, heat, or incinerate.

To replace the battery:

1. Unscrew the case locking screw and remove the front cover.

2. Observe the correct polarity labeled on the PCB and the holder.

3. Remove the old battery and dispose of it properly.

4. Insert the new battery (Figure 6) (according to the specifications in
Section 2.1).

Figure 6: Replacing the Battery

4.9 Magnetic Contact Detection

The JP5 jumper can be used to enable or disable the magnetic contact
detection, which allows the SA-02N to be used as a wireless
transmitter using its wired terminal blocks.

When the jumper is connected, the internal magnetic contact is
disabled and the terminals can be used to connect an external magnet.

If the jumper is disconnected, the SA-02N uses only the internal
magnet. In this mode, the J2 terminal blocks must be shorted together.
The terminal blocks come shorted by default.

Table 1 summarizes the settings for these 2 modes:
