Lock Release - Tynetec Entel i2 Installation Manual

5. LOCK RELEASE
The choice of electric lock release lock is left to the installer so the most appropriate type and mounting kit can be
obtained for each installation.
The lock chosen should operate from 12V DC for direct connection to the Entel i2 door panel, if an AC lock or higher
voltage DC lock is used then a separate PSU will be required.
5.01 12V DC LOCK CONNECTION
The lock release is connected directly across the door panel Lock Supply (LKSP) and Lock Return (LKRT) terminals
using 1.0mm cable.
The LKSP terminal is a +12V DC supply fused at 1A.
The LKRT terminal is a switched 0V.
DC LOCK ONLY
A reverse bias diode or a varistor/MOV must be fitted directly across all DC lock
terminals to prevent back emf from the lock coil causing malfunction
5.02 LOCK TYPE LINK SETTING
A link setting is provided on the door panel board to choose a standard (fail secure) or fail safe lock type.
With LK1 in position "A" 0V is applied during the lock release period.
With LK1 in position "B" 0V is removed during the lock release period.
A standard lock requires power to unlock (fail secure).
A fail safe lock requires power to lock (fail open).
5.03 LOCK RELEASE DURATION
The time the lock release remains open is programmable from 1 to 99 seconds, see section 7.09.
5.04 PRESS TO EXIT (PTE) CONNECTION
A N/O press to exit button can be connected across the 0V and EXLK terminals in the door panel to override the lock
release and allow egress from the building. For added safety it is recommended that the PTE button N/C contacts are
also connected in series with the lock supply wiring on fail safe locks.
5.05 TAILGATE CONNECTION
A N/C door contact should be connected across the 0V and T/G terminals in the door panel to detect when the door is
opened. This will automatically terminate the lock timer 2 seconds after the door re‐closes and reduce the likelihood
of other visitors entering during the same lock release period.
The contact is also used to illuminate the telephone LED's green to indicate "door open". If a door contact is not fitted
then T/G must be linked to 0V and the telephone door open LED's will not function.
