Notifier AIM-200 Addressable Intelligent Module

Installing the AIM-200

Complete the following steps to install the AIM-200 onto the CHS-4 Chassis.

1. Mount the AIM-200 to a CHS-4 Chassis.
2. Insert the tab on the bottom of the AIM-200 into the slot on the bottom of the CHS-4.
3. Fasten the AIM-200 to the top of the CHS-4 using the two captive screws in the top corners of the module. Refer to Figure 3-1.
4. Connect the ribbon cable. See Figure 3-2.

Note: If point annunciation (192 intelligent AIM-200 points and 56 standard system circuits) If a single AIM-200 is desired, the AIM-200 must be mounted in the second slot of the first chassis (directly to the right of the CPU). This annunciation option must also be selected in system programming.

Connecting the Alarm Bus Cable

Connect the alarm bus cable by following the steps below. Use the alarm bus cable (Part No. 71033) included with the AIM-200.

1. Remove the 2-pin connector on one end of the cable.
2. Separate and strip the wires, exposing about half an inch of bare wire.
3. Connect wires to Terminals 14 and 15 on the CPU.
4. Connect the other end of the trouble cable to the leftmost 2-pin terminal on the bottom left-hand corner of the AIM-200. If additional AIM-200s are employed, see Figure 3-3.

Wiring the Communications Loop Circuit

The AIM-200 communicates through a communications loop with intelligent and addressable initiating, monitoring, and control devices. The System 5000 can support up to ten communication loops, each controlled by an AIM-200 module. The communications loops can be wired as non-redundant (Figure 3-6), redundant (Figure 3-7), or isolated redundant (Figure 3-8).

Isolator Modules

Isolator modules (ISO-X) permit a zone of detectors and modules to be electrically isolated from the remainder of the communications loop, allowing critical loop components to function in the event of a circuit fault (see Figures 3 8 and 3-12).

Monitor Modules

Addressable monitor modules (MMX-1, MMX-2, and MMX-101) allow the AIM-200 to monitor entire circuits of conventional normally open contacts, alarm initiating devices, manual pull stations, 4-wire smoke detectors, heat detectors, and water flow and supervisory devices (Figures 3-13A and 3-14A). A type of monitor module, the addressable BGX-101L, provides point annunciation of manual pull stations (Figure 3-18).

Control Modules

Through addressable control modules (CMX-2), the System 5000 can selectively activate notification appliance circuits or Form-C output relays (see Figures 3-15 through 3-17).

Intelligent Detectors

Through the communications loop, the AIM-200 communicates with intelligent ionization, photoelectric, and thermal detectors (Figure 3-19).

Loop Capacity

The capacity of each AIM-200 includes up to 99 intelligent detectors and an additional combination of up to 99 addressable pull stations, control modules, and monitor modules. One to ten AIM-200s can be employed, depending on system requirements.

Notes

1. The communications loop is supervised and power-limited.
2. The maximum loop length is 10,000 feet (total twisted pair length).
3. Maximum loop voltage: 27.6 VDC.
4. Maximum loop current: 200 mA (short circuit) 100 mA (normal operation)
5. Maximum loop resistance: 40 ohms.
6. Refer to the proper installation drawing supplied with each communications loop appliance.

Figure 3-4: AIM-200 Wiring Requirements Non-Redundant Circuit

Branch Resistance

Short the termination point of one branch at a time and measure DC resistance from the beginning of the loop to the end of that particular branch. The total DC resistance from the panel to the branch end cannot exceed 40 ohms. Repeat this procedure for all remaining branches.

The total length of the communications loop pair cannot exceed 10,000 feet (measured from the control panel out, and back to the control panel). The DC resistance of the communications loop pair cannot exceed 40 ohms. This measurement may be obtained by disconnecting the loop out and returning at the control panel, shorting the two leads of the communications loop return together, and metering the loop out.

Isolated-Redundant Circuit

Flanking each communications loop device with a pair of ISO-X fault isolator modules protects each device from short circuit faults that may occur on other devices. For example, a fault in Zone 2 will not affect Zones 1 and 3. The isolator modules on either side of Zone 2 will open the loop. Zone 1 will still operate from power on loop out and Zone 3 will operate from loop return.

Since the system will no longer be able to communicate with Zone 2, a trouble signal(s) will be generated for that device. This circuit is a variation of the redundant circuit, therefore, no T-tapping or branching is allowed. The ratings and characteristics are the same as for the redundant circuit.

Shield Termination in No Conduit

Do not allow the shield drain wire to enter the control panel cabinet. Connect the drain wire to the outside of the cabinet via a BX-type connector.

Shield Termination in Full Conduit

The shield drain wire must be connected to the loop’s negative (-) side. Do not allow the shield drain wire or the shield foil is used to touch the control panel cabinet.

Shield Termination in Partial Conduit

Do not allow the shield drain wire to enter the control panel cabinet or the conduit. Connect the drain wire to the termination point of the conduit run (such as a single-gang box as illustrated in Figure 3-11). The conduit cannot be longer than 20 feet.Figure 3-11: Shield Termination in Partial Conduit

The Isolator Module

The loop isolator module (ISO-X) is used to protect critical elements of the communications loop from faults on other branches or sections of the loop. The ISO-X continuously monitors the circuit connected to Terminals 3 (-) and 4 (+). Upon power-up, an integral relay is latched on. The ISO-X periodically pulses the coil of this relay. A short circuit on the loop resets the relay.

The ISO-X sees this short and disconnects the faulted branch by opening the positive side of the loop (Terminal 4).  This effectively isolates the faulted branch from the remainder of the loop. Once the fault is removed, the ISO-X automatically reapplies power to the communications loop branch. Figure 3-12 illustrates the use of an ISO-X on a
non-redundant communications loop. For employing ISO-Xs on a redundant or isolated-redundant communications loop, see Figure 3-8.Shorts on this branch of an isolated non-redundant communications loop will be isolated from all devices installed both upstream of the ISO-X and on the continuation of the loop (shown as a dotted line).

Connect the four-wire circuit to MMX-2 Terminals 6 (-) and 9 (-), then 7 (+) and 8 (+). The maximum initiating device circuit resistance is 25 ohms.

Power

The MMX-2 requires a connection of 24 VDC filtered, power limited, regulated, and resettable power on terminals 3 (-) and 4(+). The maximum standby current for two-wire detectors is 2.4 mA. The maximum alarm current is 90mA.

Section Four: Programming the AIM-200

Programming the AIM-200 involves two modes of operation: Auto-Program, (password 231-1332) and Program Edit (password 231-3112). A third function, Display Status, allows the programmer to review the entire AIM-200 program. Program Clear (password 231-5678), allows the clearing of an existing program from non-volatile memory.

The Programming Display

Device Type

Green LEDs indicate whether the device is a detector or a module.Device
The device’s type and address are alternately displayed on the 2-digit 7-segment display.

Table 4-1: Auto-Programming the AIM-200

Table 4-2: Editing the AIM-200 Memory

Program LED Latch

Early version Notifier analog detectors and modules can turn on up to six LEDs on a single signaling line circuit. Notifier “R4” devices (Release 4-1-91) can turn on up to 99 detector LEDs plus five module LEDs.

Program Clear

The Program Clear function allows the programmer to clear an existing program from AIM-200 memory. After clearing memory, the AIM-200 must be completely reprogrammed, beginning with Auto-Program.
