Introduction
The SA-20 is an advanced, wireless, intrusion detector, operating on
the basis of pre-event detection. This unit operates with Rosslare's
wireless control panels, such as: AuraSys™ and HomeLogix™.
The SA-20 vibration detector combines, in a compact package, 3 types
of sensors: magnetic, vibration and movement, to provide the user a
high level of security.
It is ideal for residences, stores and warehouses, as well as paintings
and art objects. With its small size, the SA-20 can be secured at any
location, remaining inconspicuous.
The vibration detector uses a special algorithm, to monitor the area at
all times, while preventing false alarms or random events. By
performing self-calibration, the user is assured of reliable and precise
operation at all times. Other features include: battery check, Walk Test
and tamper-event reporting. The following pages outline the
installation and test instructions for your new SA-20 detector.

Installation
3.1
General
The SA-20 must be mounted on a flat surface, with the indicators top
side. For applications involving the magnetic feature, the device must
be located close to the magnet. Prior to installation, the required
features and applications must be established, so as to set internal
jumpers.
3.2
Opening the SA-20
The SA-20 cover is removed by loosening the screw and prying the
cover off. Locate the various jumpers to be set, according to the
application requirements, as defined in Section
7.
3.3
Mounting the SA-20
The detector can be installed using the provided screws and wall plugs
or it can be mounted using the two stickers on its back side (once
glued in place, the sensor cannot be moved).
It is essential to have the device on a flat surface to ensure optimum
contact with the piezoelectric sensor and with the tamper switch, both
on the back of the SA-20. In addition, the side with the LEDs should be
on top to provide ideal movement detection. For magnetic switch
applications, position the SA-20, no farther than 3 cm from the
activating magnet, with 1 cm being optimum. The recessed slot on the
left side of the cover indicates the location of the magnetic switch.
The SA-20 sensor can be used to transmit alarms from other nearby
sensors that are equipped with dry contacts (see Section
7.5).
3.4
Setting the Jumpers
Set the jumpers as described in Section
7.
3.5
Inserting the Battery
Once the device is installed, insert the battery. The 3 LEDs blink 3
times. The red LED then comes on and remains lit until the cover is
closed.
3.6
Closing the SA-20
Close the SA-20 by replacing and snapping the cover until it clicks. An
automatic calibration is performed (see Section
4). If the cover is not
close properly, the calibration process begins after 30 seconds. As part
of the calibration, a Walk Test is performed automatically to verify
correct operation of the device and its integration in the alarm system
(see Section
5). Upon successful testing, replace the screw previously
removed.
