3 FIRE PULL DOWN ALARM FIRE PULL DOWN ALARM FIRE PULL DOWN ALARM FIRE PULL DOWN ALARM Introduction to the Isolator Modules General Information The 4100/ and Quad Isolator Modules consist of two cards: a motherboard that mounts into either a CPU bay or an expansion bay and a daughter card that mount into the motherboard. The 4100/ and Quad Isolator Modules are not compatible with the IDNet Addressable Isolators. General capabilities of the isolator module include: Monitors and controls up to four loops. The 4100/ (MAPNET II) and (MAPNET II or IDNet) modules allow you to segment the entire MAPNET II or IDNet channel into four loops (maximum). Segmenting the channel simplifies troubleshooting and allows other devices to continue operating if a short circuit condition occurs on the MAPNET II loop. Note: The isolator card takes up four card MAPNET II/IDNet addresses. Class A or Class B operation. With Class A operation, if an open occurs on any loop, the isolator module energizes an internal relay that enables the B lines to carry the MAPNET II or IDNet signal. In Class B operation, the faulty loop disconnects and the other loops continue to operate. Short circuit disconnection. The isolator module disconnects loops on which it senses a short. Loops that have shorts are continuously monitored and are automatically reconnected when the short condition clears.

MAPNET II Isolator Module Overview 3

4 Introduction to the Isolator Modules, Continued Functionality The isolator operates in conjunction with the short circuit protection already present on the MAPNET II or IDNet Interface (Transceiver) Board ( ). On power up, the transceiver tests the portion of the line that it is protecting to see if any shorts exist. If a short is detected, the transceiver restricts power from flowing into that portion of the line on which the short was detected. If a short is detected after power-up, the transceiver (not the isolator) shuts down the channel for 750 milliseconds. The channel is then powered up and the isolator acts to isolate the faulty line. The short circuit trouble clears when the short is removed from the lines. The "Class A" fault status will clear only when the fault condition is corrected, and a System Reset has been initiated from the 4100 operator interface panel. In addition to short circuit protection, the isolator monitors a secondary wire pair for Class A supervision. If a break in any line is detected, the Isolator switches communications onto both the primary and secondary pairs. The isolator can also be used to disconnect communication lines and shields from the transceiver to aid in the location of earth troubles in the system, as well as other installation problems. This Loop Isolation operation can only be accomplished from the operator interface panel. Each isolator is regularly polled by the master controller to determine its current state. If the isolator does not respond, this fact will be reported as a "NO ANSWER" trouble against that device. When the device IS communicating properly, it will answer the poll with a "normal", "short circuit", or "open circuit" response, depending on the current hardware state of the system. A Correction Device Status check is made whenever a device is initialized. If the device address or location is incorrect, the MAPNET II or IDNet transceiver will ignore status messages from the isolator and will not send control messages to it. The isolator must be addressed at a valid MAPNET II or IDNet location and the job must be programmed to recognize it. LEDs The on-board LEDs, LED 1 through LED 4, indicate the trouble state of the corresponding MAPNET II or IDNet loop. Environmental Requirements Temperature: 32 F (0 C) to 120 F (49 C) Humidity: 90 F (32 C) 93% Relative Humidity (non-condensing) Standby Current 50mA at 24V 4

5 Card Configuration Overview This section contains instructions on how to configure the card via DIP switches and jumpers. Notes: The isolator is not a 4100 daughter card; rather, it is an IDNet slave. There are three different types of IDNet cards: 64-Point, 127-Point, and 250-Point capacity. Even though IDNet can support a maximum of 250 devices, higher addresses may be inaccessible because of the hardware used. Be sure that you know the model of the IDNet card that is connected to the isolator so that you can correctly set addresses for the card version you have. The System Power Supply (SPS) supports 250 devices. SW1 SW1-1 through SW1-8 are address switches. Setting a switch ON corresponds to the logic low or 0 state while setting a switch OFF equals logic high or 1. Refer to Table 1 for a complete list of the switch settings for all of the possible device addresses. Valid addresses: MAPNET II IDNet MSB LSB DIPSWITCH IS SHOWN SET AT ADDRESS 86. ON = ON 1 = OFF OFF Figure 2. DIP Switch SW1 5

ON = ON 1 = OFF OFF RESERVED FOR FUTURE USE DIP SWITCHES 1 THRU 4 DIP SWITCHES 5 THRU * MAPNET II supports address codes 1 through 127 only. RESERVED FOR FUTURE USE Dip Switch Address Setting Example Setting the Quad Isolator to address 86. Locate address 86 in the table above, this corresponds to an address setting of 0101 for DIP switches 1-4 and an address setting of 0110 for DIP switches 5-8. MSB LSB DIPSWITCH IS SHOWN SET AT ADDRESS 86. ON = ON 1 = OFF OFF 6

7 Card Configuration, Continued SW2 Switch SW2 is a rotary switch that selects the number of active loops of MAPNET II/IDNet devices. Set SW2 to position 1, 2, 3, or 4 to select the number of active loops. The Loop 1 address is set on SW1. Loops 2, 3, and 4 (if active) occupy consecutive addresses above Loop 1. Note: 1. Switch positions 0, 5, 6, and 7 are invalid selections. 2. Addresses for Loops 2, 3, and 4 must be less than 127 for MAPNETII and less than 250 for IDNet. If all 4 loops are used the highest address for MAPNET II is 124 and the highest address for IDNet is 247. JW1 JW8 Jumpers JW1 through JW8 are factory-set to specify the 27C64 EPROM ( ) in board position U11. The correct configuration for these jumpers is as follows: JW1, JW4, JW6, JW7, JW8 are out. JW2, JW3, JW5 are in. Figure 3. DIP Switch and Jumper Locations Programming Considerations The 4100 Programming Unit allows isolators to be added to any valid address. Observe the MAPNET II and IDNet address ranges as shown on Page 5. Because of hardware constraints, quad isolators must be placed at sequential addresses. The isolator uses "ISO" for both the device and point type, and requires up to four MAPNET II addresses in the configuration based on active loops selected by Switch S2. There can be up to eight isolators on a MAPNET II/IDNet channel. The custom label field is like any other MAPNET II/IDNet device. The 40-character custom label should provide enough information to help find the fault. The isolator causes no changes to lists or groups that are automatically generated by the programmer. The isolator can be included in user-defined lists, if desired. 7

8 Card Configuration, Continued Programming Considerations Isolators can be accessed using the same logical number scheme used for MAPNET II addressable devices. The allowable opcodes and qualifiers for isolators used in Custom Control equations are as follows: - ON - DISABLE - TBL, TBLACK - NORM - SHORT - OPEN - SET ON, SET OFF, SET PRI - TRACK ON, TRACK OFF, TRACK PRI - HOLD ON, HOLD OFF, HOLD PRI - DISABLE ON, DISABLE OFF - RESET - The RESET causes the device to re-try its McCulloh loop and clear the trouble bit if the trouble is cleared. The following LED programming modes are valid for isolators: - SMPL SMPL-controlled LED - T Trouble state only with Acknowledge - T AL Alert on Trouble state - ON, OFF Primary state ON, OFF - AL Alert on Primary state - DIS Track Disable state - ABAL Alert on Abnormal state - NORM Normal state - ABN Abnormal state - OPEN Open state The following switch programming modes are also valid for isolators: - SMPL SMPL Control - TOF Toggle (ON, OFF) - PST, PBH Push Button Track, Hold - HOA1 Single-relay HOA - ONOFF Up=ON; Center=Hold; Down=OFF - DE, TDE Disable, Toggle Disable There is no change to the existing programmer report format except for the addition of the new address types. The isolators use "ISO" as both the device and point type. 8

19 Wiring Overview This section contains field wiring guidelines and instructions for the MAPNET II/IDNet isolator module. General Guidelines MAPNET II communication power: Amp, 3333 bits per second. IDNet II communication power: Amp, 3333 bits per second. Refer to instructions packaged with each addressable device for its wiring connections. The Quad Isolator is not compatible with the IDNet Isolators model , Any wiring leaving the building requires overvoltage protectors where it leaves the building and another where it re-enters the building. Only four protectors total are allowed per MAPNET II or IDNet channel. If Class A wiring is not used, the Harness remains installed. Leave the Harness on all unused loops. Up to 2 isolator boards per MAPNET II or IDNet channel are allowed. Up to 43 Sounder Bases are allowed on a MAPNET II or IDNet channel, when used for coded operation. All wires must be 18 AWG (0.82 mm 2 ) minimum, or as the local code dictates. Conductors must test free of all grounds. Power must come from a Simplex-approved power supply. All wiring must be done using copper conductors only, unless noted otherwise. If shielded wire is used, - the metallic continuity of the shield must be maintained throughout the entire cable length. - the entire length of the cable must have a resistance greater than 1 Megohm to earth ground. Underground wiring must be free of all water. In areas of high lightning activity, or in areas that have large power surges, the Transient Suppressor should be used on monitor points. Wires must not be run through elevator shafts. Wires that run in plenum must be in conduit. Splicing is permitted. All spliced connections must either be soldered (resin-core solder), crimped in metal sleeves, or encapsulated with an epoxy resin. When soldering or crimped metal sleeves are used, the junction must be insulated with a high-grade electrical tape that is as sound as the original insulating jacket. Shield continuity must be maintained throughout. A system ground must be provided for earth detection and lightning protection devices. This connection must comply with approved earth detection per NFPA780. Only system wiring can be run together in the same conduit. 19

20 Wiring, Continued Power-Limited Guidelines Non-power limited field wiring (AC power, batteries, City connection) must be installed and routed in the shaded areas shown in Figure 12. Power-limited field wiring must be installed and routed in the non-shaded areas shown in Figure 11, with the exception of City wiring. Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together using the wire ties provided with the equipment. Anchor power-limited wiring to tie points, as shown in Figure 11. CONDUIT ENTRANCE FOR POWER-LIMITED WIRING CONDUIT ENTRANCE FOR NON-POWER LIMITED WIRING NON-POWER LIMITED WIRING POWER-LIMITED WIRING TIE POINT (LOCATION MAY VARY) Figure 12. Power-Limited Wiring Tie the wiring located between bays to the internal wiring troughs, if applicable. When powering remote units or switching power through relay contacts, power for these circuits must be provided by a power-limited power supply that listed for fire-protective signaling use. 20
