1 Function
1.1
The router is designed for operation
within 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 (sirens, lighted signs) via its
outputs.
1.3
The router ensures operation directly with 30 detectors
(plus two mobile devices).
1.4
The router ensures control of passive detectors and other
devices with
«dry contact»-type outputs through the
Zone-
GND
input with current control.
1.5
Power is supplied to the router from an external
redundant 10-27 V power supply unit (e.g. Astra-712/0).

4 Structure
4.1
Structurally the router is designed as a block consisting of a
base and removable cover. Mounted inside the block is a printed
circuit board (PCB) with radio elements (Figure 2).
Figure 2
4.2
Mounted on PCB are
red
and
white
LEDs
for router’s
functional status and the wireless network status supervision
respectively.
4.3
Mounted on PCB is a tamper switch, which results in the
«Tampering» notification when the cover is removed.
4.4
Mounted on PCB is a terminal block. For terminal function
see Table 1.
