!ERM Configuration
Input Requirements
The ERM accepts 12 - 24V AC/DC. An optional battery charging
module and rechargeable gel cells are available to keep the
system operational for up to 50 hours during a power interruption.
System and Keypad current draw (max) is as follows:
!Standby: 120mA
!During Operation: 230mA
Output Capabilities
Main Relay
The Main Relay will activate either a Fail-Safe or a Fail-Secure
(Non Fail-Safe) electronic locking device or other equipment. It
may also be configured as a dry contact relay output to control a
gate operator or garage door opener (Set Door Open Time to 1
second). The main output is programmable from 01 to 99 seconds
with optional timed or manual latching.
Output A
A Relay Contact output that can be programmed for one of the
following:
1. CCTV or Light Controller - First key press or ProxCard® II
(“card”) presentation to the K-Prox label area triggers a Timed
Output (1 to 99 seconds).
2. Auxiliary Output - Manual Control or Timed Output (1 to 99
seconds).
3. Second Door - Users can be assigned to open a 2nd door.
4. Doorbell - Press # at the Keypad to trigger a 1 second output
for a doorbell (not included).

Output B
A Relay Contact output that can be programmed for one of the
following:
1. CCTV or Light Controller - First key press or card presentation
to the K-Prox label area triggers a Timed Output (1 to 99
seconds).
2. Auxiliary Output - Manual Control or Timed Output (1 to 99
seconds).
3. Third Door - Users can be assigned to open a 3rd door.
4. Internal Alarm System - Detect Break-in, Door-ajar & Tamper.
5. Doorbell - Press # at the Keypad to trigger a 1 second output

!Keypad Connector Diagram
The 5 wire harness connects the Keypad to the Prox Reader.
YELLOW- Anti Tailgate
If not used, this must be connected to BLACK. By adding a door
monitor switch between YELLOW and BLACK, the door will relock
immediately after opening. If Output B is set up as Internal Alarm,
this switch will trigger the alarm if the door is opened without a
code or if the door is left open longer than the Door Ajar Time
setting.
RED, BLACK, GREEN, VIOLET, GRAY, ORANGE and SHIELD-
These wires all connect to the ERM module.

Security Level - Enabled
If SECURITY LEVEL is enabled in Set up (page 20):
When the CLOCK terminal on the ERM circuit is connected to
ground (through time clock or other switch contacts), users who
are “non-exempt” and were assigned both a code and card can
use either to enter. Those who were assigned only a card or a
code can also enter.
When the input is NOT grounded, only non-exempt users as-
signed both a code and a card can enter by using both.
In other words, “grounded” is low level security; only one form of ID
is needed. “Not grounded” is high level security; two forms of ID
are needed.
Security Level - Disabled
If SECURITY LEVEL is disabled:
Whether the CLOCK terminal is connected to ground or not
grounded, “non-exempt” users with both a card and a code can
get in by using both. All other non-exempt users are locked out.
When programming Individual Users (page 21), assigning the
Exempt from Security Level User Authorization Code (7#) exempts
a User from the security level. All “exempt” users can get in with
either a code or a card no matter what the security level is set for.
