Dangerous voltages or currents may occur due to a

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 #3258 & #3458 electric releases.
For 12 Volt door releases; use the TRINE #5204 PLUG-IN AC
LOW VOLTAGE TRANSFORMER and MODEL SR-1 SILICON
RECTIFIER
For 24 Volt door releases; use the TRINE #5201 PLUG-IN AC
LOW VOLTAGE TRANSFORMER and TRINE #SR-1 SILICON
RECTIFIER
HARDWIRED POWER SUPPLY MODELS are also available -
see our website or call our Customer Support Line for
details.
SILENT OPERATION: The TRINE #3258 & #3458 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 audible/visual
annunciating device as shown in the accompanying wiring
diagrams, Figures 1, 2 and 3 (see page 4).
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 tolerances 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 shim are supplied with the TRINE #3258 &
#3458 which may be installed as shown in Diagram 8a
and 10a to resolve this situation if this problem is
encountered. (See Figure 4 below)
