1.2 Product Description

The model 232e Keypad is designed for security and is perfect for
self-contained access control applications.Itfeaturesoutputrelays
to release the door lock, to shunt an alarm zone, and to trigger both
a propped or forced door alert. Also, the 232e Keypad contains in­puts for door monitor and REX. It allows up to 120 users.

All e style keypads are designed for both indoor and outdoor flush
mount applications. The electronics for each e keypad are conformal
coated in the manufacturing process in order to provide this level of
application flexibility. In addition, each e style keypad uses hard­ened keys to assure long-term, high-quality performance. Each e
style keypad contains illuminated clear keys that make operation in
low-light situations easy and accurate. Installation is easy. All e style
keypads mount to any standard single-gang electrical box or directly
to any wall.

Section3.U.L.Requirements

The232ekeypadisaU.L.Listedaccesscontrolunit.Thissection
contains information regarding all the requirements necessary to
meet U.L. requirements.

This system must be installed in accordance with the National Elec­trical code (NFPA70), local codes, and the authorities having juris­diction. In addition, all wires and cables used must be stranded
andshieldedU.L.Listedand/orrecognizedwire.

All interconnecting devices (that is, door contacts, REX, locking de­vices, etc.) must be U.L. Listed. A U.L. Listed access control power
limitedpowersupplymustbeusedtopowerthekeypad.

A minimum of three user codes must be programmed into the key­pad for controlling access.

3.1 Tamper Requirements

To meet U.L. requirements, a U.L. Listed tamper switch must be in­stalled in the single gang box used for mounting the keypad. The
tamper switch must activate if the keypad is removed from the box
and must disconnect power from the lock. The lock must be a fail­secure device, meaning the lock remains locked when power is re­moved. In addition, once the tamper device is activated, it must be
configured so that it can only be reset from within the protected
area. Only a Sentrol 3012 or Sentrol 3025T tamper switch can be
used. The diagrams on the next page show the suggested mount­ing location for each device.

3. Mounting

Thekeypadisdesignedtobeflushmountedusingastandardsingle­gang electrical box. In addition, itcanbeflushmounteddirectlyto
the wall surface by cutting a hole in the wall. To properly size the
mounting and wire access hole, use the installation template on the
last page of this manual and on the unit’s container.

Mounting height can vary depending on requirements. An appropri­ate range is typically between 48 and 52 inches on center off the
floor.

For outdoor installations, use a weatherproof backbox and seal the
wire entry locations with silicone and provide a drain hole. In addi­tion, use the anti-oxidant grease pack for the wire harness connec­tors.

4.2 Wiring the 232e Keypad to a Maglock (Fail­Safe)

Use the following steps to connect the 232e keypad to a Maglock
(Fail-Safe):

1. Connect the red wire (V+) to the blue wire (common), and
then connect them to the positive on the power supply.

2. Connect the gray wire (normally closed) to the positive on
the maglock.

3. Connect the black wire (V-) to the negative on the Maglock,
and then connect them to the negative on the power supply.

4.3 Wiring the 232e Keypad to an Electric
Strike (Fail-Secure)

Use the following steps to connect the 232e keypad to an electric
strike (fail-secure) (seeFigure6forreference):

1. Connect the red wire (V+) to the blue wire (common), and
then connect them to the positive on the power supply.

2. Connect the green wire (normally open) to the positive on
the strike.

3. Connect the black wire (V-) to the negative on the strike, and
then connect them to the negative on the power supply.

4.5 Wiring Remote Trigger as Request to Exit
(REX) Button and Door Contacts

Use the following steps to connect the 232e keypad to a normally
open REX device and normally closed door switch:

1. Connect the brown wire (REX Input) to the normally open
connection the REX device.

2. Connect the white/orange (loop common) to the common on
theREXdeviceandthecommonthedoorswitch.

3. Connect the white wire (door loop) to the normally closed
connection on the door switch.

Figure 8 Wiring a REX Button and Door Contacts

NOTE: By default, the REX function operates the virtual lock out­put only, but this can be changed using command 49. In addition,
the door loop does not need to be closed for the REX function to
operate, by default, but setting option 8 to 0 under command 30
programs the REX function to operate only when the door loop is
closed. This prevents the REX from re-triggering when the door is
open.

5. Testing the Keypad

After installing the keypad, IEI recommends that you perform the
keypad self-test once a year, to ensure that the keypad works prop­erly.

1. To perform the self-test, with the unit powered up, press the
following keys on the keypad:

7890#123456*

• If all 12 keypresses are accepted, the keypad enters self-test

mode.

• The LEDs alternate green, yellow, and red followed by the

sounder beeping three times.

2. Verify that the master code works correctly. (The master code
accesses program mode and activates the main relay to verify
that the locking device is working.)

The default master code is 1234.

6. Programming

To program the 232e keypad, you must first enter program mode by
pressing 99 # Master Code *. The default Master Code is 1234.

If the 232e Keypad still does not work after troubleshooting, please
call IEI’s technical support department at 1-800-343-9502 (outside
MA) or 1-800-733-9502 (inside MA). Operating hours are Monday
through Friday from 8:00 A.M. to 7:00 P.M. Eastern Standard Time.

input voltage and this is an indication of
under-voltage. The under-voltage threshold is set
to 8.5VDC, and when the voltage drops below
this limit, the low voltage warning starts and
backlighting is turned off. To solve, raise the
voltage to between 12-24V.

The 232e keypad is designed to monitor the
input voltage, and this is an indication of
over-voltage. The over- voltage threshold is set to
36VDC, and when the voltage rises above this
limit, the over-voltage warning starts and the
keypad loses all operation. To solve, lower the
voltage to between 12-24V.

Perform the programming mode loopback and
reset the master code using the programming
command.

Power is not reaching the keypad. Using a
voltmeter, confirm that there is voltage at the
keypad on the red and black wires. If there is no
voltage at the keypad, verify that there is voltage
at the power supply. If there is no voltage at the
power supply, call the manufacturer of the power
supply. If there is voltage at the power supply
but not at the keypad, verify there is no break in
the wires, then check continuity in the whole
length of the wire run. To verify that the keypad
is working, you can power the keypad with a
12-Volt Battery.

Loopback

If the master code is either not working or forgotten, power
down the system, connect the wire harness as shown in Figure 12
below, and then power the system up again. Next, change your
master code and power down the system and restore the wire har­ness to its original configuration and power the system back up.
