FOCUS 200 PLUS Installation and Setup Guide
Symptom
Marlok Construction key
causes green LED on
Keylok to light, but key
does not turn.
Construction card causes
green LED on reader to
light, but strike does not
activate.
Red LED on reader does
not "wink" off when user
card/key is
swiped/inserted.
Yellow LED on ACIU does
not flash.
Cardreader (ACIU) Comm
Fail.
Cardreader (ACIU)
trouble.
10-22
Probable Cause
1 Set screws on Keylok are
preventing key from
turning.
2 Keylok is defective.
1 ACIU battery missing or is
low.
2 Incorrect wiring from
ACIU to strike.
3 Jumper E11 is OUT.
4 Wrong strike.
5 Excessive voltage drop on
strike wires.
6 Bad strike.
7 Bad ACIU.
1 Improper or defective card.
2 DIP switch in reader not
set for operation with
FOCUS control panel.
ACIU tamper is installed and
is normal.
1 ACIU is addressed
incorrectly.
2 RS-485 terminating
Jumper E1 is not being
used properly.
3 Incorrect wiring from
ACIU to control unit.
4 Bad ACIU
1 Incorrect wiring from
ACIU to strike.
2 No strike installed.
3 Battery in ACIU is weak.
Corrective Action
1 Using a 1/16" allen wrench, unscrew (in
counterclockwise direction) the left and/or right (not
center) set screw(s) on top of the Keylok cylinder until
lock core turns freely in the desired direction(s).
2 Replace Keylok.
1 Install a fully charged battery. Make sure Jumper E11
is out.
2 Check strike wiring to TB3-1 (-) and TB3-2 (+). Check
wiring for opens, shorts, and grounds.
3 Insert Jumper E11.
4 Replace strike with one rated for 12VDC @ 550mA.
5 Check strike wire guage and length. Strike wire should
be 18 AWG minimum and length should not exceed
150'.
6 Connect strike directly to 12VDC battery. If strike does
not operate, replace strike.
7 Disconnect all wires from TB3-1 (-) and TB3-2 (+) of
ACIU. If 12VDC is not read across these terminals for
10 seconds after card is swiped, replace ACIU.
1 Card must be compatible with reader. Card should not
be cracked. Mag stripe cards should not be subjected to
strong magnetic fields. Try using a known good card.
2 Refer to Summary of Access Control Card/Key Readers
chart for proper DIP switch settings.
Release tamper.
1 Make sure ACIU is addressed for Communication
Group 4 and with a unique Unit Number (0-7).
2 Remove Jumper E1 from all devices on the RS-485 bus
except the two end devices.
3 Check wiring to TB1-3 (yellow wire) and TB1-4 (blue
wire).
4 Connect ACIU directly to control unit. If Comm Fail
persists, replace ACIU.
1 Check wiring from TB3-1 (-) and TB3-2 (+) to strike
and correct, if necessary.
2 ACIU supervises the strike. If you are using some door-
releasing device other than a strike, connect a standard
3K EOLR across TB3-1 and TB3-2.
3 Check if battery is connected and check voltage. If
voltage is low, check that input voltage from RS-485 is
greater than 12.5VDC. If bus voltage is not OK, add a
power supply. If bus voltage is OK, let battery charge
for several minutes. If voltage does not increase, check
for 12VDC minimum at battery terminals on ACIU
with battery disconnected. If voltage is not OK, replace
ACIU.
