It might also be helpful to send a gentle reminder say 24 hours before the closure or so.
To be honest, 5-day or 1-week voting timing is sometimes hard to meet. It may sound odd, but with all the workload, travel, many emails piled up, a "soft" approach may help collect more votes from all of us.

Not odd. The topic to be voted on should be placed for debate sufficiently before the vote, then an announcement of the start/end of the voting period. That way, if someone is going to be out of contact during the voting period, they may be able to submit a early on, and then if their vote changes (upon reflection/debate) it can be done so. For example: -3 weeks before the vote, the subject of the vote and schedule is announced. -1.5 weeks, initial voting is open. Initial votes can be changed. -3 days - final reminder is e-mailed and final votes open. A final vote cannot be changed. And even arrange that a vote could be telephoned/faxed in, if there is no e-mail contact available. -0 day, vote closes and tally. In this way, if there is a typhoon, there is still time to vote. If a condition takes out communications for 3 weeks, their vote is the least of their worries.
