Elevator Recall

This section contains possible solutions to application challenges. They are recommendations offered to foster a better understanding of the flexibility of Fire-Lite-Lite addressable product line. The system designer and installer bear full responsibility for the complete and correct implementation of any idea offered herein. It is recommended that the designer secure pre-approval from the Local Authority Having Jurisdiction (AHJ) for any design solution derived from any application listed here. As with any fire alarm installation, the proper functioning and operation requires full and complete testing before commissioning of the system. If you have further questions about these applications, contact Fire-Lite Technical Support.

Elevator Recall

Basic elevator recall generally requires that the system be able to recall elevators under three conditions:

1. Elevators are to be recalled to the main floor of egress (exit) when the fire hazard occurs on any floor BUT the main floor of egress.
2. Elevators are to be recalled to a secondary floor when the fire hazard occurs on the main floor of egress.
3. The Elevator system is to be shut down whenever a fire occurs in the elevator equipment room or hoist-way.

The following steps affect this elevator recall solution:

1. Identify a software zone (1-99 on the MS-9600/MS-9600LS; 1-56 on the MS-9200) dedicated to the primary recall function - recall to main floor. Enter this zone into the program for all lobby smoke detectors on all floors but the main floor of egress. Enter this zone number into the program for a CRF-300 relay to be activated by this software zone. Wire the CRF-300 relay to transfer the primary recall signal to the elevators accordingly.
   
2. Identify a software zone dedicated to the secondary recall function. Enter this zone number into the program for the lobby smoke detector on the main floor of egress. Enter this zone number into the program for a CRF-300 relay to be activated by this software zone. Wire the relay to transfer the secondary recall signal to the elevators accordingly.
   
3. Identify a software zone dedicated to the purpose of shunt trip. Enter this zone number in the program for heat detector(s) installed in the elevator equipment room and smoke detectors installed in the hoist-way to this zone. Enter this zone number in the program for a CRF-300 relay to be activated by this zone. Wire the CRF-300 relay to transfer the shunt trip signal to the elevators to shut down power in this situation.

Floor Above-Floor Below Operation

Floor Above-Floor Below operation requires for an alarm condition on any given floor, the notification appliances on the floor above it and the floor below it activate as well as the alarmed floor. To accomplish this:

•  Identify software zones for each of the floors within the installation.

•  Program initiating devices on each floor to their respective software zones.

•  For each floor, program CMF-300 Control Modules to be activated by the software zone on that floor, as well as the software zones assigned to the floor above and the floor below.

•  Initiation of an alarm on any floor will result in the activation, through the software zone assignment, of the notification appliances on the floor above and floor below that zone.

If using an MS-9600/MS-9600LS or other addressable panel, this concept can be extended to activation of two additional floors (for instance, two floors above and two floors below) because of the panel's ability to map up to five software zones to any one detector or module.

Sounder/Base

To deal with false alarms in apartment units, how can I use a B501BHT Detector/Sounder Base to achieve local notification without General Alarm?

1. Autoprogram all devices into the MS-9600/MS-9600LS or addressable panel, and the onboard NACs are automatically default-mapped to Software Zone 00 for General Alarm.
   
2. Establish a new General Alarm zone by reprogramming all outputs (NACs and control modules) intended for General Alarm to a different zone (e.g., "50).
   
3. Map each detector/sounder base in a local area to its own software zone that is not mapped to activate a NAC or control module.
   

When the control panel processes an alarm from detector and instructs the detector to latch its LED, the sounder in the base will activate. The control panel will register an alarm, the General Alarm relay contacts will switch states and the communicator will transmit the alarm, (if installed and programmed accordingly).

Note: It is recommended that you install a heat detector (mapped to a General Alarm software zone) in each local area to insure evacuation in the event of a real fire threat.

If you need more than one detector/sounder base to sound simultaneously, add a CRF-300 Control Relay to each local area. This module provides two Form-C relays that you can wire to reverse the polarity of a 24VDC connection to each of the sounder bases in the local area. Map each of the detectors in the local area to activate a dedicated software zone, say "Z02". Map the CMF-300 to be activated by this same software zone (Z02). Upon initiation of an alarm from any one of the detectors, all of the sounders in this location will activate.

Software Zones

Conventional fire panels have zones of initiating devices. When an alarm occurs, you didn't know which device initiated the alarm, but because it was wired on a particular zone, and indicated as such at the control panel, you knew the general location.

Addressable devices are not wired on zones, but are all located in a Signaling Line Circuit (SLC). The panel knows exactly which device initiates an alarm, and in response, could activate all notification appliances in the system (General Alarm). Because this is an addressable system and the panel is programmable, we have much more flexibility in defining how the control panel should react to an alarm condition. The panel can be instructed to activate its outputs selectively, based on a variety of alarm initiating scenarios. This allows the panel to react to special circumstances.

Consider the application, Floor Above-Floor Below. If a control panel could understand English, you would instruct (program) it to do the following:

Whenever an alarm occurs on the third floor, I want you to ring all notification appliances on the second, third and forth floors, but do nothing with the rest of the floors.

But the control panel doesn't know which addressable initiating devices are on the third floor, nor which notification appliances are on the third, fourth and second floors, unless you tell it. So you would have to instruct: If the Detector with address 30 initiates an alarm, activate Notification Appliance Circuits (control modules) 31, 32, 33, 41, 42, 43, 44, 21, 22, 23, 24 and 25. But imagine having to repeat this command for every detector, pull station and monitor module in the system! So to simplify the instructions that you give the control panel, it allows you to tell it which outputs will be turned on by which inputs (known as input-output mapping) using only a simple number.

When an alarm occurs, the control panel looks up which "number" has been entered by the programmer for the initiating device. The panel then identifies all of the outputs that share the same number (as programmed by the installer) and activates them.

The number that the input and output devices share is referred to as the software zone. It is a virtual wiring of outputs to inputs by a common association within the control panel's programmed memory. The Fire-Lite MS-9200 can have up to 56 software zones; the MS-9600/MS-9600LS has up to 99.

The most basic of software zones is the General Alarm zone. In the MS-9600/MS-9600LS, all inputs and outputs are initially assigned the number "00". This means that an alarm from any initiating device will activate ALL output devices. The programmer can change this default assignment for each device for special situations.
