Functional elements
Operating Principle
The siren signicantly improves the eciency of the security system, being the
most operational means of response to the intrusion into a room. With a high
probability, its alarm signal will be sucient to frighten away the intruders.

How to set Chime
Chime is a sound signal that indicates the triggering of the opening detectors when
the system is disarmed. The feature is used, for example, in stores, to notify
employees that someone has entered the building.
Notications are congured in two stages: setting up sirens and setting up opening
detectors.
HomeSiren with rmware 5.55.1.0 and later supports this function.

Performance testing
The Ajax security system allows conducting tests for checking the functionality of
connected devices.
The tests do not start straight away but within a period of 36 seconds when using

transmission: walls, inserted oors, large-size objects located within the room.
The device developed only for indoor use.
Check the signal level at the installation location.
The communication range is up to 2000 meters if there are no obstacles. Please
consider it when choosing an installation place for HomeSiren.
If the signal level is one division, we cannot guarantee stable operation of the
security system. Take possible measures to improve the quality of the signal! As a
minimum, move the device — even 20 cm shift can signicantly improve the quality
of reception.
If, after moving, the device still has a low or unstable signal strength, use a
.
Recommended installation height — 2.5 meters and more. This will complicate the
access to the device for intruders in case of intrusion.

Siren Maintenance and Battery Replacement
Check the operational capability of the HomeSiren on a regular basis.
Clean the siren body from dust, spider web and other contaminations as they
appear. Use soft dry napkin suitable for equipment maintenance.
Do not use for cleaning the siren any substances containing alcohol, acetone,
gasoline and other active solvents.
The batteries installed in the siren ensure up to 5 years of autonomous operation
(with the inquiry frequency by the hub of 1 minute) or at least 6 hours of the buzzer
