Wire Specs and Run Distances
Use this chart to pull wires in preparation of your installation:
Use metal conduit - run wires in metal conduit instead of PVC pipe. Wires run in PVC conduit may experience
interference. Metal conduits also add extra protection against lightning strikes.
Never run Data wires and High Voltage wires in the same conduit. The high voltage wires may interfere with the data
wires, possibly causing the system to malfunction.

Note:
Always provide power from a dedicated source. Plug provided transformer into an outlet wired to its own 10 Amp minimum
circuit breaker. This will prevent two problems:
Other equipment cannot introduce spikes, noise, surges, or dips into the power circuit that will affect the system.
The system's operation will not be affected if any other equipment develops a short circuit across the power line.

Common

In
The EL25 can monitor the position of up to four doors/gates and may react to a change in their
status with one of the relays (not set as a control relay). For example, if a door is pried open or is
held open after its relay deactivates, the unit will record the breach in its transactions and can
perform the following actions:
Wiring the AutoCall Feature
Using the AutoCall feature, the EL25 will automatically call the main residence phone when a
driveway sensor is activated (any device that provides a contact closure ). For example, when a
visitor drives over a loop sensor that is connected to the AutoCall feature, the EL25 will call the main
residence phone automatically so the visitor can speak to the resident without pressing the call
button on the unit.
Call the main residence phone and report the status of the door.
Energize a relay to activate an alarm device such as a siren, light, or CCTV camera.
Main use is to terminate strike time early.

Important: An Earth Ground Rod is Strongly
Recommended and should be no further than
12 ft from the unit and use a minimum of 12
gauge wire in most cases. The type and length
of earth ground rods vary by region. Contact
the building inspector’s office in the
municipality where you plan to install the
unit for correct grounding materials and
installation procedures.
Before digging, contact local
underground utility locating
companies.
Avoid damaging gas, power,
or other underground utility
lines.
Do Not ground the EL25 to a
pedestal post (gooseneck) if
one is used.

Wiring Power to the EL25
Wiring Power to the EL25
Wiring Power to the EL25
The 110 VAC outlet must be dedicated to the EL25 ONLY . This outlet should be wired back to its
own 10 Amp minimum circuit breaker. This will prevent two problems:
Other equipment cannot introduce spikes, noise, surges, or dips into the power circuit.
The system’s operation will not be affected if any other equipment develops a short circuit
across the power line.
Connect the transformer into a 110 VAC outlet
after all connections have been made. Any other type
of outlet will cause damage to the system.
