6.0 Wiring the Door(s)

Step 1. When power is interrupted from the IQ-400, the door relay de-energizes and continuity

(conduction path) exists between the Common (Com.) and Normally Closed (N.C.)

relay contacts. Should this loss-of-power situation arise, it must be determined whether

the door(s) controlled by the IQ-400 will become unlocked (or a Fail-Safe environment),

or locked (or a Fail-Secure environment).

Step 2. Refer to the two types of door hardware below and the circuit conditions that coincide

with the state of the locks.

Case A. Door Strike hardware requires continuity to unlock (for strikes that require

power to lock, follow the outline given for maglocks). This is provided by a

closed circuit condition (Normally Closed [N.C.]).

Case B. Door Strike hardware does NOT require continuity to lock (for strikes that

require power to lock, follow the outline given for maglocks). This is provided

by an open circuit condition (Normally Open [N.O.]).

Case C. Magnetic lock hardware requires continuity to lock. This is provided by a

closed circuit condition (Normally Closed [N.C.]).

Case D. Magnetic lock hardware does NOT require continuity to unlock.

This is provided by an open circuit condition (Normally Open [N.O.]).

Step 3. For Fail-Safe operation, wire the appropriate door lock hardware to accommodate an

unlocked condition upon interruption of IQ-400 power. This is implemented by:

•

For door strikes, wire between the Common and Normally Closed Door Relay

contacts.

•

For Magnetic Locks, wire between the Common and Normally Open Door Relay

contacts.

For Fail-Secure operation, wire the appropriate door lock hardware to accommodate a

locked condition upon interruption of IQ-400 power. This is implemented by:

•

For door strikes, wire between the Common and Normally Open Door Relay

contacts.

•

For Magnetic Locks, wire between the Common and Normally Closed Door

Relay contacts.

NOTE For both conditions (Fail Safe and Fail Secure) it is presumed that Lock Power is

battery backed.
