Signal-10 Maintenance
The device must behave as follows:
a) The device sounder plays a melody
b) READY LED flashes red twice per second
c) 1 – 10 LEDs is lit with red within 3 seconds
d) 1 – 10 LEDs sequentially flashes red and green alternately for 1s each. Simultaneously the device
outputs sequentially switches on with time interval of 2s
The last device output (the LAM) switching off, the Signal-10 automatically exits Self-Diagnostic mode
and returns in Operation mode.
ALARM LOOP INSPECTION
Inspect operability of each the Signal-10 alarm loop by doing the following:
1. Remove any load from the alarm input (LP) and measure the voltage across the alarm input contact.
The voltage value must range from 26.5 V to 27.5 V.
2. Connect the 4.7 kΩ resistor to the alarm input (LP) and read the loop ADC value by means of the
S2000/S2000М console by doing the following:
Enter your PIN-code by means of S2000M
Select REQUEST INFO command by 3 or 4 console button and
press ENTER, or use the 050 console button as the hot key
Select ZONE ADC command by 3 or 4 console button and press
ENTER, or use the 020 console button as the hot key
Enter the current Signal-10 network address or select the valid
value by the 3 or 4 console buttons and press ENTER
Tape the valid loop number or select it by means of the 3 and 4
buttons and press ENTER
ENTER CODE:_
v 5 REQUEST INFO
v 52 ZONE ADC
ADDRESS:_
ENTER LOOP#:_
The values which will be output by the console must range from 46 to 50.
To measure ADC values you can also use software tools such as the UProg (see Figure 10, стр. 67),
SHLEIFES and others.
