Smoke Detector Applications Guide which provides information on detector spacing placement zoning wiring and spe applications Copies of this application guide are available from System NFPA 72 guidelines should be observed This manual should be left with the owner user of this equipment The detector used with these bases must be tested and main regularly following NFPA 72 requirements The detectors should be at least once a year infOrmaTiOn relay base is intended for use in an intelligent system Form C latching contacts are included for the control of an auxiliary function The relay operate in two different modes short and long delay The activation time the short delay is used is 60 msec to 100 msec while the activation time the long delay is 6 sec to 10 sec A shunt with pin headers located on the PC board can be used to choose your desired delay B224RB is set at short delay when manufactured If you wish to use the long delay please the shunt to the adjacent pair of pin headers See Figures 2 and 6 TerminaLS fUnCTiOn Normal Close Common Normal Open Comm Line In and Out Comm Line In and Out the mounting plate directly to an electrical box The plate will mount to 4 inch

junction box as shown in Figure 2 To mount the base hook the tab on the base to the groove on the plate Then swing the base into position to engage the pins on the product the terminals on the mounting plate the base by tightening the mounting screws Install a compatible smoke detector as described in the installation for the detector 2 mOUnTing The BaSe TO an eLeCTriCaL BOX OF RELAY SHUNT

using the wire sizes The conductors used to connect smoke detectors to control and accessory devices should be color coded to reduce the likelihood wiring errors Improper connections can prevent a system from responding in the event of a fire signal wiring the wiring between interconnected detectors it is recom that the wire be no smaller than 18 gauge 0.9 square mm However sizes up to 12 gauge 2.5 square mm can be used with the base system control panels have specifications for allowable loop resistance the control panel specifications for the total loop resistance allowed wiring the detector loops inSTrUCTiOnS base uses a latching relay that can change states if it is subjected to me shocks or jarring As a result even though relay contacts are in the state when the base is shipped from the factory the contacts may have during shipment an auxiliary control circuit to closed relay contacts can cause an and possibly dangerous activation of that circuit Therefore do connect an auxiliary control circuit to the relay contacts terminals 1 2 3 before ensuring that the relay contacts are in their open state Ensure the contacts are open by applying power to the bases WITHOUT the sen heads installed wiring connections by stripping about 3 10 mm of insulation from end of the wire Then slide the wire under the clamping plate and tighten clamping plate screw the normally open NO line to terminal 3 see Figure 4 Insert the nor closed NC line of the relay to terminal 1 and the relay common line terminal 2 Wire the communication lines in and out terminal 4 the communication line in and out to terminal 5 the zone wiring of all bases in the system before installing detector This includes checking the wiring for continuity correct polarity fault testing and performing a dielectric test label is affixed to the base for recording the zone address and type of being installed at the base location This information is useful for set the detector head address and for verification of the sensor type required that location all detector bases have been wired and mounted and the loop wiring been checked the detector heads may be installed in the bases feaTUre Do not use the tamper resist feature if the removal tool is to be used detector base includes a tamper resist feature that prevents its removal the base without the use of a tool activate this feature break the tab from the detector base as shown in Fig 5A Then install the detector remove the detector from the base once the tamper resist feature has been insert a small bladed screwdriver into the slot from the top and down on the lever see Figure 5B This allows the detector to be rotated for removal tamper resist feature can be defeated by breaking and removing the plas lever from the base However this prevents the feature from being used 3 INTELLIGENT 4 4 Wiring diagram RELAY COMMON NORMALLY CLOSED NORMALLY OPEN A OPTIONAL WIRING 5a aCTiVaTing The TamPer reSiST feaTUre 6 reLaY aCTiVaTiOn ShUnT
