PROTECTION AND BATTERY TEST
When the battery voltage is lower than 5V the imago siren sets the low energy consumption mode and it
activates the "failure" [F] output. The siren check the battery efficiency each 10 hours to report a possible failure
opening the "Open collector" output [F] (universal version imago only)(normally closed 500 mA max).
SOFT-STOP FUNCTION
When the power supply voltage slowly decreases (slew rate < 100 mV/minute) the imago siren will not emit
any acoustic alarm due to loss of power supply. This slew rate is effective if detected starting from the initial
voltage (higher than 12V) to 10,5V, then the alarm activation will be prevented even in case of a sudden loss of
voltage. This peculiar function allows to avoid the acoustic warning and to compromise the efficiency and
life-time of the battery in case of protracted loss of power supply.
INSTALLATION
The siren has to be installed in a hardly accessible location to deter tamper attempts. The wall chosen must not
have any depression or protrusion in order to avoid compromising the tamper protection function. To ensure a
correct installation refer to the paragraph "Parts identification" and comply the following steps:
1. Insert stainless steel hinges and screw the nuts inside avoiding to tighten
2. Open the PC cover forcing the corners with a screwdriver
3. Remove the docking screw of the metallic undercover
4. Remove the undercover pulling it from above, taking care not to damage the electronic circuit
5. Drill the fixing bottom holes
6. Pass-through the cable coming from the Control Panel in the eyelet
7. Lock with Fischer plug the PC Base on the wall
8. Set programming jumpers (universal version imago only)
9. Insert a 6V lead battery (not supplied) and link terminals accordingly with the polarity
10. Connect cables to connection terminals
11. Verify the start up procedure
12. Close the undercover and screw on
13. Close the cover
