3 General information about the Homematic
system
This device can also be part of the Homematic home control system.
Any functionalities that result from the areas of application and con-
figuration possibilities as described in this section 3 are neither tested
by VdS nor part of the VdS certification of the HM-Sec-SD-2 wireless
smoke alarm. All devices are delivered in a standard configuration. The
functionality of the device can also be configured with a programming
device and software. The additional functions that can be made available
in this way and the supplementary functions provided by the Homematic
system when it is combined with other components are described in the
Homematic WebUI Manual. You can find the latest versions of all techni-
cal documents and the latest updates at www.homematic.com.

Function

The Homematic Wireless Smoke Alarm monitors a room for smoke emis-
sions. Operation of the device is based on the photoelectric scattered light
principle. This enables a fire to be detected at an early stage and a warn-
ing to be given in good time that dangerous smoke gases are present.
When an alarm has been triggered, the integrated siren sounds and the
warning LED starts to flash red. A white LED acts as emergency lighting
for easy orientation also in the event of power failure.
The integrated LED only serves as emergency light and is not to
be used as room lighting.
Wireless connection to other wireless smoke alarm devices
The Homematic Wireless Smoke Alarm HM-Sec-SD-2 is intended for
use in a network with other wireless smoke alarms of the same type.
Within a Homematic system, the device can be connected to max. 40
wireless smoke alarms or the Homematic Central Control Unit.

This provides an extra level of safety: In the event of fire the wireless
smoke alarm simultaneously sends an alarm to all devices of the same
type that are located within wireless range. Thus, you can react early
enough to a fire that may still be some distance away, perhaps in an-
other room on a different floor of the building.
The wireless protocol of the Homematic Wireless Smoke Alarm
HM-Sec-SD-2 is not compatible with the wireless protocol of the
Homematic Wireless Smoke Alarm HM-Sec-SD. Direct teach-in
of both device types (without the use of a Homematic Central
Control Unit) is not allowed.
In order to prevent overlaps with other wireless services in the 868
MHz band, the system works with individual wireless addresses, thus
protecting it from false alarms sent by other wireless transmitters in this
frequency range.
The wireless smoke alarm is powered by a permanently sealed lithium
battery with a typical lifetime of 10 years which enables a low-mainte-
nance operation.
