Wireless outdoor siren white, 260x200x70mm, with solar cell and lithium-polymer battery. Protection class IP54. Smart Home actuator. The purpose of the siren is to generate acoustic and visual alarm signals. The user can choose from 4 different alarm modulations by means of jumpers. The minimum volume is 85dB. Visual signals are always generated by LEDs flashing under the red cover. The siren is controlled by the central control units Safe, MiniSafe or the wireless alarm controllers FAC55D and FAC65D. Sensors that trigger alarms are taught in at the central control units or controllers. Sensor ­devices include motion sensors, door/window contacts, water and smoke detectors, temperature sensors and wireless transmitter modules. The user defines which sensors trigger an alarm and in which combination. This is supported by a cyclical wireless contact between the siren and the central unit. If this communication is interrupted during the alarm readiness, for example if the central control unit is not powered, the following may take place depending on the position of the jumpers in the siren: No reaction. 2 short acoustic or visual signals at intervals of 10 seconds (as-delivered state). Short 1 second acoustic and visual alarm at intervals of 10 seconds. Alarm triggered immediately. The maximum length of the alarm is adjustable to 1, 3 or 5 minutes by means of jumpers in the siren. The as-delivered state is adjusted to 1 minute. Install the siren in a place that is sheltered from the rain and where there is enough sunlight to charge the solar cell on the top of the device. A daily exposure to normal daylight for a few hours in sufficient to retain the change in the internal battery. To protect against theft or manipulation, the mounting panel is fitted with a contact which immediately triggers the alarm if the siren is removed from its mount.
