In a similar manner, the lock will also accept a new master card. Any new master
card used in a lock will automatically void the previous master card.
Battery Operation – HT28 Dual / ADVANCE Dual
Onity locks are powered by 4 AA size alkaline batteries. These batteries are expected
to last between 2 and 4 years, depending on a number of factors. Factors that can
shorten battery life are:
• The freshness of the batteries when they are purchased.
• The number of transactions per day.
• Extreme cold weather.
• Battery quality.
Onity recommends the use of major brand batteries in the locks, such as Energizer,
Duracell, and Panasonic batteries. In installations where the lock will be subjected to
extremely cold temperatures, use 4 AA size Lithium batteries. Both Alkaline and
Lithium batteries may be purchased through Onity.
A low battery indication is given to staff cards for approximately one month prior to
the batteries being completely dead. The hand-held Portable Programmer can also be
used to check the level of the batteries.
Audit Trail – HT28 Dual / ADVANCE Dual
Onity locks use non-volatile memory to store a record of the most recent openings.
The Onity HT28 Dual / ADVANCE Dual records the last 500 openings. This means
that the locks will not lose the audit trail, even if the batteries are removed. Reading
the lock will produce a list of all cards used in the lock and the date and time they
were used.
Real Time Clock – HT28 Dual / ADVANCE Dual
The Onity lock circuitry contains a "real time" clock. This means that the lock is able
to determine if a card should be admitted based not only on the code of the card, but
also the date and time.
Daylight Savings Time Change – HT28 Dual / ADVANCE
Dual
With the software, Onity locks can be loaded to automatically change for Daylight
Savings Time. The lock will remember the date of the next change. This means that
the lock must be loaded twice each year with the date of the next change.
Panic Operation – HT28 Dual / ADVANCE Dual Onity locks feature panic
retraction of the deadbolt from inside the guestroom. Operation of the lever from
inside the guestroom retracts both the deadbolt and the latch, fulfilling the
requirements of various building codes, life safety codes, and the ADA.
