RECOMMENDED INSTALLATION SEQUENCE:

1. Verify strike is proper for the door into which it is to be
installed.

2. Verify that you have all parts required to complete the
installation.

3. Verify that the new electric release operates with the
existing power supply/control circuit (retrofit
applications); or verify that the new power supply/
control circuit operates the new electric release (new
installations).

4. Locate and clearly mark the circuit breaker which
provides ac power to your transformer/ power supply
or that supplies power to the receptacle into which you
will plug your transformer/power supply. This will
enable you to safely cut power during installation, and
permit troubleshooting if required.

5. Verify that the receptacle or circuit providing power to
the electric release is not controlled by a wall switch,
time clock, or other external device.

6. Verify that the circuit/receptacle used for the locking
system is not powering any other equipment.
Remember that interruption of power to your locking
system could prevent access into the protected area,
or jeopardize the security/safety of the site's
occupants.

7. Verify that the door and associated components are in
good working order.

8. Install electric release as per attached guidelines.

9. Wire electric release as per attached guidelines.

10. Perform final test of completed installation.

LUBRICATION: The TRINE Model #3234, #3234W & #3478
do not require lubrication. Lubricating these units will actually

hamper their performance by attracting dust and debris into the
tight tolerance precision Micro Solenoid assembly.

GETTING STARTED: Before proceeding with your
installation, verify that the door to which the electric release is
being applied is in good working condition.

DUTY & VOLTAGES: The TRINE Model #3234, #3234W &
Model #3478 are available as FAIL-SECURE (Normally Locked,
Power to Unlock), INTERMITTENT DUTY and are supplied in
two different operating voltage and the LC VERSION, suitable
for use in a range of voltages from 12V to 24V AC or DC. The
TRINE Model #3234RS, 3234WRS & Model #3478RS are FAIL­SAFE (Normally Unlocked, Power to Lock), continuous duty and
are supplied with LC module.

These items are essential for either new installations or retrofits
Items which should be specifically checked prior to beginning
the installation include:

The hinges (or pivots) are in good condition
If your installation is a retrofit, that the existing latch

lines up perfectly with the existing strike plate.
The door is not rubbing on the saddle or anywhere on
the frame
The door closer is not leaking and is in good condition
and properly adjusted.
The door is not warped or otherwise damaged which
might hamper its operation or otherwise affect your
installation or the final system's performance.
That the door frame member into which the door
release is to be installed is deep enough (1 inch) for the
body of the electric strike, and that the wiring to
operate the electric release can be installed for your
application.

HANDING: The TRINE Model #3234, #3234W and #3478 are
non-handed.

The TRINE MODEL # 3234, #3234W and #3478:
FAIL-SECURE "INTERMITTENT DUTY" units are designed for

momentary application of voltage for access control purposes,
and cannot be continuously powered without permanent and
irreversible damage to the electric strike's solenoid.

The TRINE MODEL #3234-RS, #3234W-RS and #3478-RS:
FAIL-SAFE "CONTINUOUS DUTY" versions may be used for

applications where the release must remain UNLOCKED for
extended periods. Please contact TRINE for other additional
TRINE electric release solutions for those applications requiring
a continuous duty FAIL-SECURE electric release that may be
powered for extended periods, commonly referred to as
CONTINUOUS DUTY.

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 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 lock­latch 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).

TROUBLESHOOTING THE COMPLETED INSTALLATION:

SYMPTOM: Electric release is not actuating:

1. Verify proper voltage is present AT STRIKE. If voltage IS present: the strike may have been damaged
during the installation, or dirt or debris may be preventing proper operation.

2. Verify for proper electric release coil resistance (REFER TO COIL ESISTANCE CHART), for either a short
circuit or open circuit. Coil is NOT a serviceable part. Note that intermittent coils can only receive

power for 1 minute or less.

3. If voltage IS NOT present:



Verify Circuit breaker is on



Verify voltage at the transformer/power supply output.



Verify output from rectifier (if used)



Verify that there are no additional, unknown external switches or devices which may be interrupting

your circuit.



Check for damaged wiring or bad wire splices.

SYMPTOM: Door will not open but strike is working



Check for other locks on door



Check for proper lock-latch engagement (SEE SECTION: "CONFIRMING PROPER LOCK-LATCH

ENGAGEMENT & CLEARANCES").



Lock latch engagement may be not set correctly. (If proper clearance cannot be achieved by installing

a shim; a shorter lock latch may be required for your installation.)



Check for excessive backpressure on door release latch by following these steps:
While observing the electric release and latch; apply enough pressure on the door so that the lock's
latch does not press on the electric release's latch. If applying pressure as described does not cause
any movement of the lock away form the latch, then there may be too much pressure on the electric
release's latch. If electric release works properly while you are applying this pressure, then steps must
taken to relieve this pressure. Possible remedies include:



Re-adjust (or install) a door closer



Remove door silencers



Correct excessive door warpage



Re-center electric release in jamb



Remove or trim weather stripping around the door
