Additional Information
1. The LED's on the interface board are defined as: A = Heartbeat: 1 second flash, A & B ON = Deleting
card database.
2. Output K2 is energized for 1 second when there is a door forced open or door held open alarm. The
door position is monitored by input I1 and the door monitor contact is normally closed. The held
open timer is fixed at 45 seconds.
3. Request-to-exit (REX) input I2: uses a normally open switch. Output K1 is energized as long as the
REX input (I2) is closed.
4. Jumpers J3 and J4 are not used.
Maintenance
The SR-10A readers are designed to provide continuous service with minimal routine maintenance.
However, contaminants (such as magnetic oxides from badges and dirt) tend to accumulate on the
read head. Without regular cleaning, these contaminants will shorten the read head life and increase
the probability of card read error. A maintenance schedule should be developed base on the card
reader environment (dirty or clean) and the usage frequency (light traffic or heavy traffic). Extreme
case may require daily cleaning.
Head cleaning may be done by using disposable, pre-saturated magnetic head cleaning card. These
cards are readily obtainable from a number of sources (e.g. Clean Team Co., www.cleanteam.com,
800-888-8830; KIC Products, www.kicproducts.com, 207-514-7030; System ID, www.systemid.com,
888-648-4452).
The reader exterior surface is covered with high strength polymer and polyester membrane. It may
be cleaned with a soft cloth and mild detergent if required.
