Page 6: Installation
5750H002 Ed.03 4.- Installation WARNING -Transmitters/detectors supervise a point and not an area. If the gas leak does not reach the sensor, or the level of concentration in that point does not reach the foreseen values according to the type of gas (see page 3) no alarm will be activated. If perimeter supervision is required, several sensors should be installed around that area. -
Page 7: Assembly
5750H002 Ed.03 Assembly -Remove the bezels (1) from the unit. -Loosen the screws (2) by turning them a 1/4 turn and open the cover (3). -Drill the holes needed for the cable entry glands using the pre-stamped centres on the sides of the housing for guidance. -
Page 8: Wiring
5750H002 Ed.03 Wiring The wiring between the transmitter and the station must NEVER be installed in a conduit together with power, control or power supply cables. Always disconnect the power supply to do the wiring. Cables for wiring the relay contact should have an adequate section depending on the unit to be connected. Certain international standards maintain that the power supply of the alarm should originate from a different circuit to that used by the refrigeration and ventilation system. -
Page 9: Setup Wizard
If 1 minute elapses without any key being pressed, the transmitter will automatically proceed to demo mode*. AKO-575400 only 3-.The display will show the message Gc2. Use keys N and Q to select the type of gas to be measured (ALL, 134A, 404A, 407A, 410A, 125, 448A, 449A or 407F , and press SET to confirm. -
Page 10: Operating Modes
Choose this option if the transmitter is connected to a compatible alarm station. In this mode, the acoustic alarm is disabled and the output is configured to communicate with the station. Compatible stations: AKO-555241 AKO-555242 AKO-558241 Ÿ AKO-558242 AKO-55624 AKO-55724. - Page 11 5750H002 Ed.03 Set Hold mode Prevents false alarms when charging or cleaning the chambers. While this mode is activated, pre-alarms will not signal and alarms will signal as pre- alarms when faced with all effects (sound, relay activation and signalling). To activate/deactivate this mode, press the key for 3 seconds.
- Page 12 5750H002 Ed.03 Alarms The transmitter emits an acoustic alarm, the alarm indicator flashes and activates the relays when certain gas concentration levels are exceeded. If the transmitter is connected to a station, the station will emit the acoustic alarm. The relays will be activated in both devices. There are two alarm levels depending on the concentration of gas detected: Pre-Alarm and Alarm.
