Does the MHK GSM gate opener support 4G, or only GSM and 3G?

The MHK GSM controller lists GSM quad-band and 3G WCDMA 900/2100 MHz, but its 4G support is not specified. 2G and 3G networks are being phased out in many countries, so confirm with your SIM operator that they will stay available, or choose the MHK 4G model, which lists LTE bands, from POWERgate Abu Dhabi.

How should the MHK GSM controller's adjustable 0–900 second relay time be set?

The MHK GSM controller has a NO/NC relay with adjustable time from 0 to 900 seconds, rated 3A at 250V AC or 20A at 14V DC. Use a short pulse for a gate start input, such as on the DEA NET24N board, and a longer time for a light or barrier hold, then confirm the setting method with POWERgate Abu Dhabi.

The MHK GSM controller is DC 9–36V only — can it run from my gate board's accessory supply?

The MHK GSM controller runs on DC 9–36V at 1A, drawing 25 mA on average and 50 mA at most, so take power from a DC accessory output. An AC-only supply would need a rectifier or adapter, which is not listed in the pack, so check your board's output and ask POWERgate Abu Dhabi.

At AED 150, what is supplied with the MHK GSM controller, and how many users can it hold?

At AED 150, the MHK GSM controller handles up to 200 authorised numbers, but its pack contents, antenna, and manual are not specified. Ask POWERgate Abu Dhabi on WhatsApp +971 50 884 4933 what is supplied, and add a warning lamp such as the FAAC XLED, because a gate opened by phone can move unseen.
