SIGNALS
CENTRAL UNIT
- red light: During the first 25 seconds after switching on, this light will flash in inverted
mode (short PAUSES). After this time it will flash regularly (short FLASHES) every 0.8
seconds to signal that the system is ready to trigger an alarm.
- green light: This light is on when there is an external power supply (mains voltage or
12V).
- yellow light: This light comes on briefly every time the central unit infrared sensor
detects a movement, both when the alarm system is armed or disarmed.
C21 SENSOR
- red light: This light comes on briefly every time the infrared sensor detects a move-
ment, both when the central unit is armed or disarmed.
After detection, the sensor is excluded for 2 minutes in order to limit internal battery
consumption.
- low battery signal: When the red light flashes briefly for approximately one minute af-
ter each detection, this means that the battery should be replaced as soon as possible.
Caution: Failure to replace the battery may generate false alarms.
C22 - C25 - C27 - C28 SENSORS
It is advisable to replace the lithium batteries in the sensors every 2-3 years.
Caution: Carry out general checks on a yearly basis for optimum system efficiency.
C319 REMOTE LED MODULE
This module has a red warning LED which indicates the status of the central unit (ar-
med or disarmed):
- red light off: system disarmed;
- red light blinking: system armed.
CENTRAL UNIT ALARM MEMORY
The central unit has an alarm memory that signals any alarms occurring during your
absence as well as indicating which sensor generated them.
