AKO-55424 Trapped Person Alarm
Product Information
The AKO-5542H412 Ed.03 is a trapped person alarm that emits a bi-tonal sound in case of an emergency. It comes with an auto-configuration push-button and input indicators. The alarm and push-buttons should be installed in a place protected from vibrations, water, and corrosive gases, where the ambient temperature does not exceed the value indicated in the technical data. The station should be located in a monitored area, where it is guaranteed that people able to alert to the presence of alarms will be present. Neither the alarm nor the push-button are suitable for areas classified as potentially explosive.

Warnings
- The alarm and push-buttons should be installed in a place protected from vibrations, water and corrosive gases, where the ambient temperature does not exceed the value indicated in the technical data. The station should be located in a monitored area, where it is guaranteed that people able to alert to the presence of alarms will be present.

Wiring
Always disconnect the power supply to carry out wiring. The wiring between the push-button and the station must NEVER be installed in a conduit alongside power, control or supply cables. For disconnection, the power supply circuit must be equipped with a switch of at least 2 A, 230 V, located near the device. The power supply cable will be H05VV-F or NYM 2 1×16/3. The section to be used will depend on current local regulations, but should never be less than 1.5 mm . Cables for wiring the relay contact should have the relevant section for the device to be connected. The 120 / 230 V~ wiring area must be kept clear of any other external element. Ensure that you have connected the batteries before starting up the device. Certain international standards indicate that alarm power supply should originate from a different circuit to that used for the refrigeration and ventilation system. Be sure to comply with current local regulations.
