dead, then just hold a fresh 9 volt

alkaline battery to the contacts,

enter the existing combination,

and turn the outer ring whilst

holding the battery in place.

If you place the battery in the

wrong polarity position, nothing

will happen. The keypad will not

not beep and the diode will not

flash. Just reverse the battery and

the lock will open. These contacts

are labeled External Emergency

Power Terminals.

Another basic function includes

a wrong try penalty. If four wrong

combinations are tired, the lock

will shut down and not accept any

input through the key pad. The

diode will blink every 10 seconds

until the waiting period is over.

The combination can be

changed on this series of locks in

the standard way, the 0,1,2, or by

using the optional combo gard

programmer. These days, we

change combination, or reprogram

combination locks. Progress!

The 0,1,2 changing procedure is

easy and simple to remember.

First enter 6 zeros, 0,0,0,0,0,0.

Then enter the existing

combination once. When the pad

beeps, enter the NEW

combination twice.

After each enter, there

are beeps. Now, try the

new combination and it

should work. If you

have messed up, the old

combination will be the

default combination.

ADVANCED

FUNCTIONS

The 33E series locks

can be further pro-

grammed with advanced

functions. TO do this,

however, a hand held

electronic programmer

is needed. LaGard Part

number is #3405 hand

held programmer. With

this optional unit, fur-

ther features can be

incorporated into the

33E series locks. These

include:

1. Second user

2. Time delay, 1 to

99 minutes, and an

opening

window of between 1 -

19 minutes.

3. Time delay override

-Emergency opening

4. Dual Combinations

5. Silent Signal Alarm

6. Remote override signal

I will not dwell on these

functions for a very basic reason.

The programmer costs about

$275.00, but before you can buy it,

you must receive training on how

to use it. The basic 33E series

lock costs $109.00 and can be used

to retrofit most combination locks

without prior instruction or use of

the programmer module.

INSIDE STUFF

I took the mounted lock apart to

see some of the inside functions. I

have included some of the

schematic (blown apart) picture of

the 33E series locks for

consideration (see Illustration B).

I found a couple of interesting

parts that I missed on the

diagrams. Photograph 4, shows

the inside of the lock with the

spindle cam marked with a magic

marker arrow. The arrow in this

picture is pointing to the solenoid

(similar to the one on the 3300

swing bolt series of locks) that

blocks the movement of the lock

bolt. This solenoid is larger than

the swing bolt unit and beefier.

Photograph 5, has the arrow

pointing to a relock spring

incorporated into the lock. If the

back cover is broken off, this

Photograph 4. The arrow points to the tip

of the solenoid that blocks movement of

the combination bolt.
