Unit IV SYSTEM OPERATION

STARTUP PROCEDURE

CAUTION

Placing the controller in the Bypass mode inhibits its outputs, preventing actuation of any extinguishing or alarm circuits that are connected. For maximum safety, however, secure output loads (remove power from any devices that would normally be actuated by the system) before manually testing the system. Remember to place this same equipment back into service when the test is complete.

1.After setting the DIP switches and making all electrical connections, apply power to the controller.

2.Perform the Checkout Procedure.

3.If the controller appears to be operating normally (performs power-up countdown and then shows ‘Nor’ on the display), remove mechanical blocking devices and restore power to the extinguishing loads.

NOTE

Be sure that the detector is correctly aimed at the potential hazard and that no obstructions interfere with its line of vision. UV absorbing gases should not exist between the detector and the potential hazard.

CHECKOUT PROCEDURE

CAUTION

W hen testing the system, be sure to secure all output devices to prevent unwanted activation of this equipment and remember to place these same devices back into service when the check-out is complete.

MANUAL vi CHECK/COUNT TEST

The Autom atic vi (visual integrity) feature checks the detectors for correct response.
