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.

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.

Supervisor The supervisory signal is routinely transmitted to the
panels every 20 minutes, advising the Tamper
Status, Battery Status, and Event Activation Status to
the panel
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.
