1 Function
1.1
The detector is designed for manual
activation of a fire alarm by pressing the
driving
element,
forming
«Fire»
notifications, and transmitting them to the
Astra-Zitadel System Control Panel via
radio.
1.2
Power is supplied to the detector
from one or two lithium-thionyl-chloride
batteries (primary and secondary), size
AA, voltage 3.6 V.
2 Operating Principle
The detector is activated by pressing the actuator
– indestruct-
ible plate. After being pressed the plate locks in the pushed
position.
Microprocessor forms «Fire» notification in accor-
dance with pre-set algorithm.
The detector is returned to standby mode by returning the
actuator to an initial state with a key-pusher.

Structure
5.1
The detector is designed as a block consisting of a
removable cover and a base, made of high-impact plastic
(Figure 2).
Figure 2
5.2
Mounted inside the cover is a printed circuit board (PCB)
with radio elements and slots for the primary and secondary
batteries. The recessed part of the cover also contains an
actuator with an inscription that clearly marks the place and
direction to be pressed
5.3
The upper section of the recessed part contains white or
yellow shutter, which emerges when the actuator is pressed.
5.4
Mounted on PCB is a tamper switch (S1button), which
results in the
«Tampering» notification when the cover is
removed.
5.5
Mounted on PCB are LEDs for the detector
’s operability
supervision.
