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 – indestruct­ible plate. After being pressed the plate locks in the pushed
position. Microprocessor forms «Fire» notification in accor­dance with pre-set algorithm.
The detector is returned to standby mode by returning the
actuator to an initial state with a key-pusher.

5 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.

Notes
1 The «Power failure» notification is processed by the red LED

if both batteries are discharged or if one of the batteries is
missing and the second battery is discharged.
2 If «Primary battery failure» notification appears, replace
the battery within two months.

7 Pre-starting Procedure

7.1 After transportation in conditions differing from those of

operation, keep the detector unpacked for 4 hours in the
expected operating conditions.

7.2 Switching Detector On, Replacing Batteries

WARNING! Lithium-thionyl-chloride batteries have an effect of

«passivation» to provide the possibility of long-term storage. To
provide battery normal operation after long-term storage, hold
an «activation» procedure.

Step-1

Insert the mortise key into the
slotted opening on the left side of
the detector.
Turn the key counterclockwise
while simultaneously shifting the
cover upwards.
Separate the cover from the base.

Step-2

When using one battery to switch the detector ON, insert the
main battery (Primary).

When using two batteries, it is
recommended to insert the
backup battery (Secondary)
first, and then the main battery
(Primary). The backup battery
can be inserted up to 1 minute
after inserting the main battery.
To replace the battery, remove
the old battery, wait at least
30 seconds, and insert the new one.
The LED lights up one time for 1 to 40 seconds – the battery
activation and checking period.
If after 40 seconds the red LED flashes with a triple blink
every 25 seconds, activate the battery by removing it, waiting
at least 30 seconds, and reinserting it.

Warning! If two batteries have been inserted, replace
both batteries.

7.3 Registering the Detector in the Wireless

Network

Detector registration is required for detector identification within
the wireless network in which it is supposed to operate.

Step-1

According to Astra-Zitadel System Control Panel`s

Operating Manual * perform the following procedure:

1) Install Software ** (MSS Astra-Z, Pconf-Z or MSS Astra

Pro) intended for configuring Control Panel.

2) Create wireless network

Step-2

Perform par.7.2

Step-3

Switch the control panel to Wireless device registration
mode by the method described in the appropriate Control
Panel Operating manual *

Step-4

Initiate detector registration by one of 2 methods:
a) using the LT (step-5);
b) using the Reg plug and the tamper switch (step-6)

WARNING!
Avoid to initiate registration procedure on several
detectors simultaneously

Step-5

Initiating Detector Registration Using the LT:

- Press the lower button on the LT and hold until a beam
appears.

- Direct the laser beam at the
detector LED.

- Irradiate the LED for 1
second.
The detector red LED lights
up for 2 seconds, and then
the detector switches to
wireless network search
mode and the white LED
lights up at a frequency of 5

Hz.

Step-6

Initiating Detector Registration
Using the Reg Plug and
Tamper Switch:

1) Press the detector actuator to

release the microswitch
compressed spring.

2) Shortly (for 1-2 seconds)

connect the Reg plug with a
screwdriver.

The detector switches to
registration in wireless network
mode for 60 seconds.

3) Within 60 seconds, shortly press the tamper switch on

the detector. The detector switches to wireless network
search mode and the white LED lights up at a frequency of
5 Hz.
