This manual provides detailed information on spacing placement zoning wiring and special applications and is at no charge from System Sensor For installation in Canada refer to Standard for the Installation of Fire Alarm Systems and CEC 1 Sec 32 This manual should be left with the owner user of this equipment The detector used with this base must be tested and maintained following NFPA 72 requirements The detector should be cleaned at once a year DESCRIpTION B404B detector base is designed for use with System Sensor model 2451 2451TH photoelectronic and 1451 ionization detector heads The capabil of plugging these detectors into a variety of special bases makes them more than equivalent direct wired models Refer to the System Sensor cata for other available plug in bases B404B base is intended for use in 4 wire systems with terminals provided power remote annunciator and relay connections This base also contains resistor to provide current limiting in the alarm state TERMINALS Annunciator Coil Used Annunciator Relay A Contacts Relay A Relay C Contacts detector base mounts directly to 31 and 4 inch octagon boxes and square boxes with or without plaster rings To mount the base remove decorative ring by rotating it in either direction to unhook the snaps before the ring from the base Use the screws supplied with the junction box attach the base to the box through the appropriate mounting slots in the base the decorative ring around the base and rotate it in either direction the ring snaps into place see Figure 2 gUIDELINES wiring must be installed in compliance with the National Electrical Code applicable local codes and any special requirements of the authority hav jurisdiction using the proper wire size The conductors used to connect detectors to control panels and accessory devices should be color coded reduce the likelihood of wiring errors Improper connections can prevent a from responding properly in the event of a fire signal wiring the wiring between interconnected detectors it is recom that the wire be no smaller than 16 gauge 1.5 square mm and that or three conductor wire be no smaller than 18 gauge 1.0 square mm best performance alarm loop conductors should be installed in separate conduit or shielded cable to protect the alarm loop from extraneous interference detectors and alarm systems control panels have specifications for al loop resistance Consult the control panel manufacturer specifica for the total loop resistance allowed for the particular model control being used before wiring the detector loops installations where

wire slide the bare wire end under the clamping plate tighten the clamping plate screw Use the strip gauges molded into the and underside of the base for ease of wiring to terminals 1 and 4 and terminals 6 through 14 respectively zone wiring of the detector base should be checked before installing the detector heads The base contains a built in shorting spring to make possible After the detector base is wired and mounted to an electrical position the shorting spring against terminal 3 This temporary connec energizes the supervisory relay and permits the wiring of the loop to for continuity all detector bases have been mounted wired and the wiring checked the detector heads The shorting spring in the base automatically disen when the detector head is removed from the base DO NOT remove the spring since it reengages as the detector head is turned into the base the circuit fEATURE detector base can be made tamper resistant so it cannot be removed TAB AT DOTTED LINE BY
