Operation, Maintenance and Installation Manual

Alarm Mode Configurations:

All "e" (economy) series control panels will only have a combination "test-normal-silence" switch where

automatic alarm reset is the only alarm conﬁguration. When the panel goes into alarm, press the switch to

"silence" and the buzzer will turn off but the alarm indicator will remain on until the lag/alarm or alarm

level switch deactivates and automatically resets the alarm system.

All other Check It series control panels employ separate "test" and

"silence" switches. These panels can be ﬁeld modiﬁed to have a "manual"

alarm reset. Refer to ﬁgure for placement of an 18 AWG jumper wire to

convert the panel from automatic reset to MANUAL reset. In the Manual

Reset mode and when the panel goes into alarm, the panel will remain in

alarm even if the alarm level switch is "opened" until the "silence" switch

is activated. This feature allows alarms to be manually acknowledged

before the alarm is cleared. In the event of a power failure, the alarm is

also cleared.

WARNING! When using the manual alarm reset feature you

must use a four ﬂoat system. If you're using a 3 ﬂoat system, add a fourth ﬂoat and remove the yellow jumper

wire between the lag and alarm terminals to avoid dry pumping.

Use 18 AWG wire approximately 4" long. Strip off ¼" outer insulation. Insert jumper wire into the 2 posi-

tion wire port (one wire per port). To remove jumper wire, press small screw driver or pointed object onto

the "white" port block and remove wire as the wire is held in place by a spring cage terminal device.

Circuit Board Terminal Blocks:

The Check It series control panel uses two terminal blocks. A 10 position main terminal block is for power

and level switch connections. A separate 3 position terminal block are for dry auxiliary contacts. A 5 amp,

120 VAC max load can be applied to the auxiliary terminals. The auxiliary contacts are Form C, Single Pole,

Double Throw. (Common, Normally Open, Normally Closed). Contacts change state when in alarm condi-

tion.
