!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: 50mA
!During Operation: 150mA
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. The main output is program-
mable 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 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).

!Keypad Connector Diagram
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.

TIME CLOCK
If TIME CLOCK is enabled in Set up (pages 20 and 21), when the
CLOCK terminal on the ERM circuit is connected to ground –
through time clock or other switch contacts – all codes work
normally. When the CLOCK terminal is not grounded, only those
codes with 24-hour Access Authorization (page 21) will function.
The disabled codes are still considered valid and will not trigger
Tamper Alarm if tried repeatedly.
