SA-11
Self-powered Outdoor siren
with flash light
USER'S MANUAL
DESCRIPTION
SA-11 is a self-powered optical-acoustic warning unit for outdoors, comprising an electronic siren and
flashing light with a rechargeable battery backup. The embedded system is built around a RISC
microcontroller that controls all its functions, performs self-tests and permanently checks connections with
the alarm system. The siren is triggered either by an external trigger with selectable polarity or by
interruption of the supply voltage. It features an independent external flash control input and a service
input to disable functioning during installation, service, etc. The microcontroller also monitors the backup
battery charging.
SA-11 is protected by double casing: weather resistant plastic on the outside and a metal cover on the
inside. A built-in tamper switch enables the system to recognize removing the cover off the unit or
removing the siren off the wall. SA11 is equipped with a magneto-dynamic horn siren.
