TESTING & MAINTENANCE

Pressing the 

TSPL

 turns off the light on the 

TSPL

 and forces the unit into emergency mode, interrupting power to the designated 

A.C. ballast. The emergency lamp is now being lit by the 

P-320

 unit. After releasing the

 TSPL

, the fixture returns to normal operation 

after a momentary delay. 

Initial Testing

 – Allow the unit to charge approximately 2 hours, then press the 

TSPL

 to conduct a short discharge test. Allow a 24 

hour charge before conducting a one hour test.
The 

P-320

 is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety Code, outlines the 

following schedule:

Monthly 

– Insure that the 

TSPL 

is illuminated. Conduct a 30 second discharge test by depressing the 

TSPL

. One lamp should oper-

ate at reduced output.

Annually

 – Insure that the 

TSPL 

is illuminated. Conduct a full 1½ hour discharge test. The unit should operate as intended for the 

duration of the test.

“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”

SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL. 

Consult Customer Service or visit www.iotaengineering.com for current warranty information.

OPERATION

Normal Mode

 – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The 

P-320

 is in the standby 

charging mode. The 

TSPL 

will be lit providing a visual indication that the battery is being charged.

Emergency Mode

 – The A.C. power fails. The 

P-320

 senses the A.C. power failure and automatically switches to the 

Emergency 

Mode

. One lamp is illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power is restored, the 

P-320

 switches 

the system back to the 

Normal Mode

 and resumes battery charging. See page 1 of the Instruction Manual.

LAMP SELECTOR SWITCH

The 

P-320 

has a lamp selector switch that can be used to optimize the performance. Refer to the table below for the optimal setting 

of the lamp selector switch for your lamp type.
