The ASD-100 wireless smoke and heat detector is designed for operation as part of the
ABAX two-way wireless system. It is supported by the ACU-100 controller with firmware in
version 1.06 or later.
The ASD-100 detector is signaling alarm after detection of visible smoke (optical detector) or
after registration of high temperature (thermal detector). The thermal detector responds to
exceeding the specified temperature threshold and a high rate of temperature rise. It is
possible to activate / deactivate and select operating mode of the thermal detector by radio.
The operating modes correspond to the classes (A1, A2 or B) defined in the EN 54-5
Standard. The class determines conditions (temperature threshold and temperature rise rate)
in which alarm is to be signaled. The detector will be sending information on the alarm until
its causes (smoke, high temperature) cease to exist. Alarm signaling by means of
buzzer/indicator LED will last for a preprogrammed period of time.
The ASD-100 detector is equipped with a buzzer, the operating parameters of which
(activation / deactivation of signaling, selecting one of 3 sound signals, duration of signaling)
are programmed by radio.
The detector is supplied from a CR123A 3 V lithium battery which ensures operation for
approx. 3-year period. The detector controls the battery status. When the voltage drops to
2.6 V, the "low battery" information is sent to the controller. The low battery signaling
continues until the battery is replaced.
Explanations for Fig. 1:
1 - housing base.
2 - electronics board.
3 - red LED indicator. After
smoke or heat is
discovered, the LED will
be on for a preset period
of time. Additionally, when
in test mode, the LED will
signal communication with
the controller and fouling
of the optical chamber
(during polling) or alarm
memory: quick blinking –
alarm was caused by the
smoke detector; slow
blinking – alarm was
caused by the heat
detector. Quitting the test
mode will reset the alarm
memory.
4 - base of optical chamber.
5 - cover of optical chamber with labyrinth.
6 - housing cover.

indices on the edges of base and cover which facilitate
positioning when the housing is being closed.
