The supervisory card SC-91A provides two Class A/B alarm initiating supervisory circuits to recognize the activation of a normal-

ly open switches (tamper, low air, temperature, etc.) Each zone is equipped with individual alarm (yellow) and trouble (yellow)

LED’s for diagnostic ease. This card plugs into the second edge connector slot of the Main Board (MB-91A) and/or any Expander

Board module (EB-91A/M) slot.

Important:

jumper settings must be positioned as noted.

Supervisory Alarm

- A shorted supervisory device will initiate a supervisory alarm mode of operation. The on-card “ALARM”

(yellow) indicator will light steady and the “SYSTEM TROUBLE/SUP” (yellow) indicator on the Control Card CC-91A will light

steady. The System trouble buzzer will sound and the common supervisory and common trouble contacts on the MB-91A will

transfer.

Trouble

- An open in the detection loop will initiate the circuit into a trouble condition and activate the trouble buzzer located on

the MB-91A. The respective zone “TROUBLE” (yellow) indicator as well as the “SYSTEM TROUBLE/SUP” indicator on the

CC-91A will activate
