Edco EL-EDS
Electric Lock Suppressor
The Edco EL-EDS suppressor kit is intended for installation with electrical
switching devices that are connected through a relay contact on typical access
control panels.
The Edco EL-EDS protects against electrical anomalies (transients) that are
generated as a result of the collapsing electrical field of an electromagnetic
switching device (maglock or electric strike). The Edco EL-EDS provides
protection for both relay contacts and control panel.

Installation
The diagram (left) illustrates the proper installation of the Edco
EL-EDS. For each maglock or electric strike circuit, you will need
to install a suppressor (1) across the relay contacts and (2) across
the leads connected to the lock solenoid (locate as close as
possible to the solenoid). The suppressor wires can be installed
without regard to polarity. If your package does not contain two
(2) devices, contact your distributor.
