1 Function
1.1
The router is intended 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 TM identifier code transmitting to
control panel via radio.
1.5
The router ensures control of passive detectors and other
devices with «dry contact»-type outputs through the Zone-
GND input with current control.
1.6
Power is supplied to the router from a 10-27 V power
supply unit.
1.7
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 2 200 mA/h.

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).

insertion
holes
4.2
The base has a slot for installing BAT. The PCB has a
socket for connecting BAT outputs.
Mounted on PCB are red and white LEDs for router's
4.3
functional status and the wireless network status supervision
respectively.
4.4
Mounted on PCB is a tamper switch, which results in the
«Tampering» notification when the cover is removed.
4.5
Mounted on PCB is a terminal block. For terminal function
see Table 1.
