Fire Alarm System Limitations An automatic fire alarm system–typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control with remote notification capability–can provide early warning of a developing fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.
Installation Precautions WARNING - Several different sources of power can be connected to the fire alarm control panel. Disconnect all sources of power before servicing. Control unit and associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until this manual is read and understood. CAUTION - System Reacceptance Test after Software Changes.

2. Installation Mounting the Enclosure. Select and remove the appropriate knockout(s) on the ABS-8RF enclosure. Securely mount the enclosure. Ground the enclosure to a solid electrical ground per NEC Article 250. Pull all wiring into the enclosure (refer to "UL Power-limited Wiring Requirements" on page 17). Wiring the Power Terminal Blocks 24 VDC power supplied by the host control panel or external power supply must be regulated and power-limited.
2. Installation Wiring the Relay Terminal Blocks Wiring the Relay Terminal Blocks The ACM-8RF provides eight relays with Form-C contacts rated for 5 amps. Note: Wiring from these relays is not supervised. The terminal assignments are illustrated below. For information on wiring limitations, refer to "UL Power-limited Wiring Requirements" on page 17.
2. Installation Wiring the EIA-485 Terminal Blocks Wiring the EIA-485 Terminal Blocks Communications between the Fire Alarm Control Panel and the ACM-8RF is accomplished over a two-wire EIA-485 serial communications bus which must be power-limited. Communications between the host FACP and ACM-8RFs is supervised by the fire alarm control panel. Wiring Specifications • The EIA-485 circuit cannot be T-tapped; it must be wired in a continuous fashion from the control panel to the ACM-8RFs.
2. Installation Wiring the EIA-485 Terminal Blocks EIA-485 Shield Not in Conduit When the EIA-485 wiring is not in conduit, terminate the shield at the outside of the FACP cabinet. Do not allow the shield to enter or even touch the cabinet housing the ACM-8RFs. Between ACM-8RFs, wire-nut multiple shields together outside of the respective enclosures. Ensure that the shield does not touch earth ground at any junction points. TB 2 ACM8RF-term2.
