ELECTRICAL:
If you are performing a new installation, be
certain that you make provisions for the proper voltage power
supply for your electric strike. If you are performing a retrofit
type installation, determine that the voltage present at the
location of the strike is appropriate for the TRINE strike you
have, that the circuitry supplying the voltage is operating
properly, and also verify that you are able to cut the power
completely to the door location so that you may perform the
installation safely without endangering yourself or causing
damage to the power supply or other devices connected to the
circuit. It is strongly recommended that you also test for high
voltages which may exist between each lead of the power wiring
to the electric release solenoid, and to the door frame which is
an earth ground. Dangerous voltages or currents may occur due
to a miswire or other pre-existing fault conditions in the system
you are servicing.
TESTING YOUR ELECTRIC STRIKE; POWER SUPPLY; &
SWITCHING CIRCUIT PRIOR TO FINAL MOUNTING OF THE
ELECTRIC RELEASE IS RECOMMENDED
POWER SOURCES:
The TRINE MODEL #5208 (12 VDC) or MODEL # 5209 (24
VDC) are suitable DC POWER SUPPLIES which are plug-in
and therefore do not require that the installer perform line
voltage wiring.
TRINE offers several low voltage transformers suitable for use
with the TRINE MODEL #3234, #3234W & #3478 electric
releases.
HARDWIRED POWER SUPPLY MODELS
are also available -
see our website or call our Customer Support Line for details.
SILENT OPERATION:
The TRINE #3234, #3234W & #3478 are
referred to as "Silent Operating"; unlike some types of AC
electric releases which make a "buzzing sound" when activated.
For some applications, such as entrances into apartment
buildings or storerooms, an audible sound is desirable, and
even expected. For other applications, such as offices, silent
operation is preferred because a buzzing sound is distracting or
disturbing. Verify with your client which they require, and if an
audible signal when the electric release is activated is desirable,
then add a sounding device as shown in the accompanying
wiring diagrams.
CONFIRMING PROPER LOCK-LATCH ENGAGEMENT &
CLEARANCES:
The latch and the lock must engage properly for the electric
strike to operate as intended. On doors where the gap between
the edge of the door and the jamb are within standard tol-
erances and the latch is the proper length, no adjustments will
be required and this is true for the majority of installations.
But too little lock-latch engagement will result in an installation
were the door may be easily spread; allowing the locked door to
be forced open.
Too much lock-latch engagement will result in a situation where
the door release will interfere with the door latch, causing
binding; improper operation and premature mechanical wear on
the latch and release.
Extended latch length (LL) minus the gap (G) between the edge
of the door and the edge of the jamb equals the amount of lock-
latch engagement.
"Lock-Latch Engagement = LL - G"
INSTALLATION OF SHIM:
An adequate amount of clearance must exist between the door
latch and the strike keeper so that they do not interfere or bind
when the door opens or closes. Two 1/16" thick shims are
supplied with the TRINE #3234, #3234W and #3478 which may
be installed as shown in the "Installation Drawings section" to
resolve this situation if this problem is encountered. (also See
Figure 4 below).
