FAQs: Battery/Power

How do I power the PIM?

The PIM must use a UL approved, FCC compliant power supply that is capable of supplying a voltage between 7.5 to 14.0 VDC at a peak current of 300 mA. If the ACP can supply this power use it, otherwise a separate power source is required (recommendation: Schlage Wireless Access part number: PS-9VDCR-300mA). (back)

How long will the batteries last?

The life of the battery pack is dependent on usage and the frequency of the WAPM's heartbeat. The MIRL/ WISI battery pack is capable of providing power for 2.5 years with 40,000 card swipes/presentations per year with a ten-minute heartbeat period. It will provide power for four years at 20,000 card swipes/presentation per year with a 10-minute heartbeat interval or two years at 25,000 card swipes/presentation per year with a one-minute heartbeat interval. These battery lives are for an access point without a request to exit or door position switch installed. The WPR's battery pack life will be longer than the MIRL or WISI (no lock/strike to drive and it has an on/off switch). (back)

What kind of batteries are used?

The MIRL, WISI, and WPR use 8 flat top (no buttons) "AA" battery cells, the cells are welded into a battery pack with insulation and a battery connector added. Therefore standard, off the shelf, "AA" battery cells cannot be used. Battery packs must be obtained from Schlage Wireless Access, it's representatives, dealers, or distributors. (back)

How do I get in the door if the battery is dead?

If the "low battery" trouble is ignored and the WAPM's battery is allowed to go completely dead, there is a jack on the inside of the MIRL and the underside of the WISI's reader that allows the battery operated WAPM to be "jump started" by using a 9V battery and special cable. This will temporarily power up the WAPM long enough to swipe a valid card and unlock the access point to change the battery. If the dead battery is on an MIRL, a mechanical key override may be present to accomplish the same thing. (back)

How long before the battery goes dead does “low battery" trouble occur?

A battery powered WAPM ( MIRL, WISI, WPR) will continue to operate for about 1 month (normal operation) after indicating a "low battery" condition. (back)

When does a “low battery” trouble occur?

A "low battery" trouble will be reported from an MIRL, WISI, or WPR when it's battery has enough energy remaining for 1 month of normal operation. (back)
