3.2 Configuring the Solenoid

The solenoid can operate in either fail-safe or fail-secure mode. Fail-safe means the

solenoid is energized in the locked position and is then de-energized when unlocked.

This also means when power is lost the solenoid is de-energized and the door is

unlocked. Fail-secure is the opposite, meaning the solenoid is de-energized in the

locked position and is then energized when unlocked. When power is lost the solenoid

remains de-energized and the door is locked. This is selected with dip-switch 5 on

switch S1 on the Reader. When this switch is open the unit is in fail-safe mode and

when the switch is closed it’s in fail-secure mode. Refer to the table in section 3.6 for

the dip switch setting.

3.3 Enabling the Tamper Switch

Each Reader has a magnetic Hall Effect switch, which is used as a tamper switch. To

enable the tamper switch close dip-switch 7 on switch S1 on the Reader. Each interior

escutcheon is equipped with a magnet. When the magnet is in place, the tamper relay

on the Interface Module is energized and LED6 is on. This is the normal condition,

indicating the door is secure. When the magnet is removed the tamper relay de-

energizes and LED6 turns off. This indicates the unit was tampered with.

When more than one Reader, with the tamper switch enabled, is connected, the

magnets must be in place on each Reader for it to operate properly. When a magnet is

removed from any one of the Readers, the tamper relay de-energizes.

There is an additional tamper option, which is used to indicate if a door goes offline (due

to a malfunction or was disconnected from the Interface Module). To enable this option

close dip-switch 4 on switch S1 on the Interface Module. Now, if a Reader goes offline,

the tamper relay de-energizes. Please note that the tamper switch does not need to be

enabled on the Reader for this feature to work.

3.4 Configuring the Reader LED Operation

The Reader has a red/green bi-color LED on the on the front of the keypad. The red

LED operation is controlled by dip-switch 6 on switch S1 on the Reader. When this

switch is open the red LED is off. If you close dip-switch 6, the red LED turns on.

You can use the bi-color LED to indicate the status of your control panel by changing

the LED to green when the door is unlocked. The LED control terminal on the Interface

Module is used to control the status of the LED on the Reader. Dip-switch 3 on S1 on

the Interface Module selects how the LED control terminal operates. When this switch

is open the LED turns green when the terminal is pulled low (ground). When this switch

is closed the LED turns green when the terminal is pulled high (positive voltage).
