1 Function
1.1 The router is intended for operation in the
Astra-Zitadel system.
1.2 The router is intended:
- for retransmitting messages (notifications,
control commands, responses, handshakes,
etc.) from wireless devices within the Astra-
Zitadel system through all retransmission levels
to the control panel;
- for automatically routing messages from
wireless devices if the current data transfer route is
lost;
- for controlling external devices connected to the router jack
and powered with 220 V AC.
1.3 The router ensures operation directly with 30 detectors
(plus two mobile devices).
1.4 Power is supplied to the router from 220 V AC network.
The router has 220 V AC circuit protection.
1.5 The router retains operability if the mains AC voltage
varies within the range of 100 to 240 V.
1.6 The router has the potential to connect a backup power
supply unit: a lithium ion polymer rechargeable battery
(hereinafter BAT) of LP704374 type with nominal voltage of 3.7
V and a capacitance of 2200 mA/hour.

4 Structure
4.1 Structurally the router is designed as a housing combined
with a 220 V plug and jack. Mounted inside the housing is a
printed circuit board (PCB) with radio elements (Figure 2).
Figure 2
4.2 The base has a slot for inserting BAT. The PCB has a
socket for connecting BAT outputs.
4.3 Mounted on PCB are red and white LEDs for router’s
functional status and the wireless network status supervision
respectively.
4.4 Mounted on PCB is a button for initiating the network
registration procedure without housing opening.
