ASD-110
WIRELESS SMOKE AND HEAT DETECTOR
The ASD-110 multisensor detector can detect the early stages of fire development when
there is some visible smoke and/or temperature rise. It can operate as a stand-alone device
or as part of the ABAX two-way wireless system. It is supported by the ACU-100 controller
with firmware version 3.02 (or later) and by the INTEGRA 128-WRL control panel with
firmware version 1.10 (or later).

1. Features

• EN54-7 compliant visible smoke sensor.
• EN54-5 compliant heat sensor.
• Red LED for optical signaling.
• Built-in sounder.
• Test feature.
• Tamper switch (supervised when working in the ABAX system).

2. Functional description

An optical method is used for the detection of visible smoke. When the concentration of
smoke in the optical chamber exceeds a given threshold, an alarm is triggered. The smoke
sensor operating parameters are modified depending on the temperature changes recorded
by the heat sensor (thermistor).
The heat sensor operates according to the requirements of Class A1R (EN 54-5). The alarm
will be triggered after exceeding a certain threshold temperature (54°C - 65°C) or in the event
when the temperature rises too rapidly (see Table 1).

The alarm is indicated visually (LED steady light) and acoustically (intermittent sound) for 2
minutes. Pressing the test / reset button (designated with the letter A in Figure 1) during the
alarm will clear the alarm condition. The alarm information is sent to the ACU-100 controller /
INTEGRA 128-WRL control panel. After the alarm causes cease to exist, information about
the alarm end will be sent.
After starting the test mode in the ABAX system, the LED indicates as follows:
− flashing quickly – the memory of alarm triggered by smoke sensor;
− flashing slowly – the memory of alarm triggered by heat sensor;
− a single short flash – the detector is being polled (there was no alarm).
