Tamper Alarm Led (Red) - Technoalarm TP4-20 User Manual

TP4-20 - User Manual
Once the alarm has stopped, the led is switched off.
CONTROL PANEL IN STAND-BY
Led on = alarm stored (alarm memory)
The led becomes lit on disarming of the control panel, and is
lit until the program is armed again.
Led off = no alarm
Zone alarms are stored in the event buffer of the control panel
with indication of date and time of beginning and end of alarm.
2.3.3 TAMPER ALARM LED
(RED)
The red tamper led signals tamper and zone tamper alarm. These
alarms are direct and are always detected, even if the control
panel is in stand-by, in case of:
Opening of the tamper input (ZT)
Opening of the tamper contact of a console or a module
connected via serial bus
Transection of the connection cable of a detector (zone
tamper alarm)
Zone tamper alarm is detected only by the inputs with
double end-of-line resistor contact (B24).
Short circuit on the connection cable of a detector
Opening of the tamper contact of a detector
CONTROL PANEL ARMED

2.3.4 BATTERY LED
(YELLOW)
The yellow battery led signals low battery alarm. This alarm is
direct and is always detected, even if the control panel is in
stand-by, in case of:
Battery voltage drop below the minimum level guaranteeing
correct functioning of the control panel (11V)
Battery voltage drop below the minimum level guaranteeing
correct functioning of a wireless device (2.7V)
The led produces the following signaling:
Led blinking = alarm active
The led starts blinking upon voltage drop below the limit
and continues blinking until battery restore.
Led on = alarm stored (alarm memory)
The led becomes lit upon battery restore and remains lit on
disarming of the control panel (if it is armed), and in any
case until it is armed again.
Both events, low battery and battery restore, are stored in the
event buffer with indication of date and time.
