SIGNAL-20P DESIGN AND OPERATING PRINCIPLES

4.4 Device operation modes

The device is designed to operate in following available modes:

− Technical readiness mode

− Operating mode

− “Power Failed” mode

− Diagnostic mode

− “Device Failed” mode

The device “Ready” indicator statuses corresponding to various de-

vice operation modes are shown by the Table 8.

4.4.1 Technical readiness mode

The device enters the technical readiness mode when voltage has

just supplied to the device power terminals. The duration of this mode is

not to exceed 3 seconds provided at least one device input is supplied by

no less than 11V.

4.4.2 Operating mode

After technical readiness mode having been finished the device en-

ters the operating mode, that is, monitors and analyses the alarm loop

statuses, controls the relays, transmits messages and receives commands

from the net controller.

The operating mode is accompanied by lit “Ready” indicator.

4.4.3 “Power Failed” mode

The device enters the “Power Failed” mode if one or both (see sec-

tion 4.3.1) input voltages have fallen below 10 V. In such a mode the de-

vice performs its operations and besides produces the “Ready” indicator

signal and generates the “Power failed” message.

Both input supply voltages having fallen below 9 V, the device cuts

off. The input supply voltages (any or both – see section 4.3.1) having ex-

ceeded 11 V, the device automatically transits from “Power Failed” mode to

the operating mode generating the “Power Restore” message.

4.4.4 Diagnostic mode

The device transits from the operating mode to the diagnostic mode if

the tamper code pattern has been pressed. Refer to the section 6.1.2 for

more detailed discussions.

4.4.5 “Device Failed” mode

The device enters the “Device Failed” mode if the microcontroller

memory test has failed. The microcontroller memory test is carried out

each time the device power has been up. In such a mode the device
