Figure 6: Connecting the Locking Devices
You can set each output independently for fail-safe (power to lock) or fail-secure
(power to unlock), see
Programming the Door Data
for more information.
Calculate voltage drop on existing wire run:
Use a large enough wire gauge
for the cable between the EK1000 and the lock to provide at least the minimum
voltage required to operate the lock. The resistance of the cable and the current
drawn by the lock will determine the gauge of wire that you should use.
Fire Escape Safety
You must install an Emergency Override switch for any fire door or escape route
to unlock the electric locking device during an emergency (see Figure 6).
Typically you would install fail-safe locks (power to lock) with a normally closed
break-glass or touch bar switch in the lock's power cable. When someone
operates the break-glass switch, the power to the lock is removed causing the
door to unlock without intervention from the EK1000.
Alarm Output Relay (Easikey 1000 Plus Only)
The Easikey 1000 Plus
provides a relay on each door
channel with Common,
Normally Open, and Normally
Closed terminals. Alarm relays
active when an Unauthorized
Access alarm or a Reader
Tamper alarm event occurs.
Alarm Relay 1 activates when
alarms occur on Reader 1. Alarm Relay 2 activates when alarms occur on
Reader 2. Each relay deactivates when the door closes, or when the system
administrator acknowledges the alarm.
The relay contacts are rated at 2 Amps at 24V AC or DC.
Door left Open warnings do not activate the alarm relays.
Channel Interlock assigns Relay 1 to both door channels:
When you use
Channel Interlock, alarms on both readers activate Alarm Relay 1. The EK1000
will not activate Alarm Relay 2.
