M300CJ Module(See wiring diagram Fig. 5 for M300RJ)

GENERAL

M300CJ Control Module The M300CJ Address-able Control Module provides Johnson Controls intelligentcontrol panels a circuit for Notification Appliances (horns,strobes, speakers, etc.) or to monitor a telephone circuit.Addressability allows the M300CJ to be activated, eithermanually or through panel programming, on a select (zoneor area of coverage) basis.

M300RJ Relay Module The M300RJ AddressableRelay Module provides the system with a dry-contact outputfor activating a variety of auxiliary devices, such as fans,dampers, control equipment, etc. Addressability allows thedry contact to be activated, either manually or through panelprogramming, on a select basis.

FlashScan (U.S. Patent 5,539,389) is a new communi-cation protocol developed by NOTIFIER Engineering thatgreatly enhances the speed of communication between ana-log intelligent devices. Intelligent devices communicate in agrouped fashion. If one of the devices within the group hasnew information, the panel CPU stops the group poll andconcentrates on single points. The net effect is responsespeed greater than five times that of other designs.

FEATURES Built-in type identification automatically identifies these

devices to the control panel. Internal circuitry and relay powered directly by two-wire SLC

loop. The M300CJ module requires power (for horns, strobes,etc.), audio (for speakers), or a telephone riser (for hand-sets). Internal relay feature available on FlashScan systemsonly.

Integral LED blinks green each time a communication isreceived from the control panel and turns on in steady redwhen activated.

LED blink may be deselected globally (affects all devices). High noise immunity (EMF/RFI). The M300CJ may be used to switch 24-volt NAC power,

audio (up to 70.7 VRMS) or telephone. Wide viewing angle of LED. SEMS screws with clamping plates for wiring ease. Direct-dial entry of address 01 159 on FlashScan sys-

tems (IFC-640, IFC-3030), or 01 99 on traditional systems(IFC-400, IFC-640, IFC-1010/2020, IFC-3030, or FC-2000).

Speaker, audible/visual, and telephone applications maybe wired for Class B or A (Style Y or Z).

APPLICATIONSThe M300CJ is used to switch 24 VDC audible/visual power,high-level audio (speakers), or control telephone devices. TheM300RJ may be programmed to operate dry contacts for doorholders, Air Handling Unit shutdown, etc., and to reset four-wire smoke detector power.

CONSTRUCTION The face plate is made of off-white Noryl. Controls include two rotary switches for direct-dial entry of

address (01-159). The M300CJ is configured for a single Class B (Style Y) or

Class A (Style Z) Notification Appliance Circuit. The M300RJ provides two Form-C dry contacts that switch

together.

OPERATIONEach M300CJ or M300RJ uses one of 159 possible moduleaddresses on a SLC loop. It responds to regular polls fromthe control panel and reports its type and status, includingthe open/normal/short status of its Notification Appliance

Circuit (NAC). The LED blinks with each poll received. Oncommand, it activates its internal relay. The M300CJ super-vises Class B (Style Y) or Class A (Style Z) notification orcontrol circuits.

Upon code command from the panel, the M300CJ will dis-connect the supervision and connect the external power sup-ply in the proper polarity across the load device. The discon-nection of the supervision provides a positive indication tothe panel that the control relay actually turned ON. The ex-ternal power supply is always relay isolated from the com-munication loop so that a trouble condition on the externalpower supply will never interfere with the rest of the system.

Rotary switches set a unique address for each module. Theaddress may be set before or after mounting. The built-inTYPE CODE (not settable) will identify the module to thecontrol panel, so as to differentiate between a module and asensor address.
