Connecting to the Zoning Control Unit

Zoning Control Unit - Step 1

STEP 1. Before turning the unit on, connect both ends of the fiber sensing loop into the fiber loop receptacles on the back panel of the unit.

a. This device contains a class I laser. Do not look directly into the fiber loop receptacles while the device is powered.

b. The fiber receptacles on the back of the unit are for FC or SC connectors. Be sure the key on the FC connector is lined up with the slot in the receptacle before tightening the connector.

Terminal Block – A 3-pin terminal block is located in the back panel to provide a normally open (NO) and normally closed (NC) contact to trigger an external alarming device (siren, flashing light, etc.). This connection is a switch capable of carrying 3 amps (3A) of current.

STEP 4. It is recommended the alarm be tested by deliberately triggering the unit into alarm condition with a fiber event (fiber attenuation, fiber disconnect, or cover cop activation).

a. The red "alarm" LED should light in alarm.

b. The audible alarm should sound, if the "Mute" button is off.

c. If the unit is in "Latch" mode, the red "alarm" LED and audible alarm will be present even after the alarm event has been corrected. Press the reset button to clear the alarm if in "Latch" mode.
