imago wls outdoor siren

The imago self-powered outdoor siren is a professional (acoustic & optical) Sounder which shows a unique and exclusive design, extremely slim (max. 6 cm thickness) associated with a state-of-the-art technology aimed to combine the best possible performances with the maximum energy saving:

high sound pressure, power LED alarm light and 2 LEDs for auxiliary signaling.

The siren is handled by two microcontrollers:

- One deals with major processing, in order to verify all conditions and to perform all required actions

- One for the RF communication channel management (bi-directional) for receiving commands, sending alerts, diagnostic, etc.

The microcontrollers are synchronized in their processing by an appropriate exchange of information. imago wireless offers the choice between two power supply solutions:

1. a proprietary alkaline battery pack 7,5V 8Ah, non-rechargeable (to be replaced)

2. an external power supply (9÷12Vdc) with recharheable lead-acid battery 6V 1,2Ah

The charging status of the batteries and, if necessary, the level of external power supply are constantly monitored. The warnings of failure, missing or low batteries are reported to the main system.

  1. At temperatures below -5° C the siren may give a “wrong battery” message
  2. Working below -5°C significantly reduces battery life
  3. Replace the battery pack using only the model KSI7207580.000
  4. A battery can explode if handled incorrectly – do not recharge, open or throw on a fire
