Warnings, cautions, and notes
The following warnings, cautions, and notes apply to the wiring diagrams
included in this appendix.
Warnings
1. Before connecting mains AC, make sure the circuit supplying primary power
is turned off and the conductors are deenergized. High voltages capable of
causing personal injury or death may be present.
2. Before connecting standby batteries, make sure the panel is energized.
Connecting batteries before applying AC power can cause personal injury.
Cautions
1. The middle terminal of the AC terminal block is connected to the chassis even
when the ground wire is removed.
2. Connecting standby batteries with the battery leads reversed can cause
equipment damage.
3. For initiating device circuits and notification appliance circuits, break the wire
run at each field device to provide proper connection supervision. Do not loop
wires under the terminals.
Notes
1. All wiring is power-limited except for mains AC and battery wiring. All wiring is
supervised unless noted otherwise.
2. Maintain 1/4-inch spacing between power-limited and nonpower-limited wiring
at all times. Keep power-limited wiring in the shaded area and nonpower-
limited wiring in the unshaded area as shown in Figure 13.
3. The dialer, if installed, must be the first piece of equipment on the protected
premises’ telephone network. We recommend that you install a listed surge
protector between the dialer and the public switched telephone network as
shown in Figure 23.
4. Relay outputs are not supervised and do not provide current limiting. Connect
relays only to power-limited sources.
5. If you connect an RPM module that is configured to transmit separate alarm,
supervisory, and trouble signals to a control panel that has an F-DACT(F),
you can’t use the F-DACT(F) as a dialer.
