FS-250 Installation and Operation Manual

Observe the wiring order -- the bottom terminal is ground and must be wired back to the

electrical panel ground (earth) bonding point or another good ground acceptable to the

authority having jurisdiction and the electrical inspector. The neutral wire must be taken

back to the electrical panel neutral distribution bar and must not be grounded.

Dangerous voltages will be present on this terminal block and on other components

surrounding it and the transformer when the AC supply is turned on. Do not touch.

Battery Installation

WARNING

Improper battery connections or shorting battery terminals may damage the system and/or

batteries and may cause personal injuries.

Place the batteries in the space provided in the bottom of the back-box. If a larger than 12

AH battery set is required, a separate enclosure, CAB-BATT or any enclosure UL Listed for

Fire Protective Signaling Use, must be used.

The control panel uses a 24V battery set. Connect the two 12V batteries (or four 6V

batteries) in series with wire that is rated for the maximum worst-case battery current draw.

Route the battery leads to the left of the enclosure and up to the battery connector, J4. The

battery leads are not power-limited. DO NOT CONNECT BATTERIES YET.

Powering The Control Panel

Apply AC power to the control panel. The AC POWER ON LED, SYSTEM TROUBLE LED,

and the trouble buzzer should be on.

Observe polarity. Connect the B- (black) lead from the main board into the black or -

terminal of the battery set and the B+ (red) lead from the main board into the red or +

terminal of the battery set.

Instructions are provided with each optional module. Follow these instructions for proper

installation.
