Longmire Fire Alarm Data - Summary

Pull Box #’s– EOC Panel Zones Below is a breakdown of all pull‐box and hydrant data visible on the Longmire Development Water System Plan (Figure 3-13), followed by a concise narrative summary of how they tie into the fire‐alarm zones and water‐main layout. Photos to Follow.

1. Pull Boxes (P.B.) and Zone Assignments

The map shows 10 pull boxes (P.B. 1–P.B. 10), each labeled red/yellow on the plan. On the right side of the image, a handwritten table lists each Pull Box (P.B.) number alongside its corresponding “zone” (the EOC panel zone). Transcribing directly from that table yields:

Pull Box ID

Approximate Location (Nearest Building/Line) Assigned Zone

P.B. 1 Southernmost pull box, on Line D just north of the Nisqually River. It sits adjacent to building L-165 (southern tip of the site).

P.B. 2 South‐central cluster: on Line A at the intersection with Line F, immediately northwest of the “Radio Shop/Electric Shop” (building L-203).

P.B. 3 Central‐northern cluster: on Line D just east of the Triplex/Radio Shop area (between buildings L-210, L-211, L-212).

P.B. 4 On Line D, slightly west of the Triplex/Electrical/Fire‐Cache Radio Shop (L-203). 15

P.B. 5 East side of the campus, on Line B right next to building L-116 (Longmire housing).

P.B. 6 On Line A at the T-junction near building L-117 (Longmire housing) and adjacent to L-113/L-112.

P.B. 7 At the heart of the campus, adjacent to the Administration Building (L-001), on the 8″ main where Line C meets Line B/A.

P.B. 8 North of P.B. 7 on Line C—just west of building L-110, slightly south of L-128 (transitional area between admin and housing).

P.B. 9 Northernmost pull box on Line C, immediately south of building L-130 (northern housing).

P.B. 10 On the far eastern edge (Line B), adjacent to the Duplex near the Nisqually River (building L-131/L-133 area).

Notes on the “Location” column:

• The plan’s various “Line A–F” notations correspond to the water‐main branches (4″, 6″, 8″) as shown in the map legend.

• Each P.B. is placed next to—or in very close proximity to—a main building/residential cluster.

• “Nearest Building” refers to the building label (L-###) printed on the map.

2. Hydrant Assemblies (H: #) and Water‐Main Sizes

There are 15 hydrant assemblies marked H 1–H 15 (red outlines with “H:#”). Each hydrant sits on either an 8″, 6″, or 4″ water main (per the legend). Below is a table enumerating hydrant ID, approximate location, and the main size (in inches) on which it taps:

– Slightly thinner line = 6″ or 4″ water main (map uses two intermediate line weights)

– Dashed thin line = service laterals (2″ & smaller)

– Hydrant symbols (“⊗” with an H in red box) mark each Hydrant Assembly.

– Pull‐Box symbols are circles with a “2” inside and “P.B.” next to them, all highlighted in yellow/red.

3. Narrative Summary

1. Overall Purpose This drawing is the “Longmire Development Water System Plan,” which integrates both the fire‐ protection water infrastructure (8″, 6″, 4″ mains, hydrant assemblies) and the electronic fire‐alarm pull‐box network (P.B. 1–10). In a historic campus like Longmire, each pull box ties into a specific fire‐ alarm zone, while hydrants ensure that ample water flow is available for firefighters. Both systems must meet NFPA 72 (alarm) and NFPA 14/25 (hydrant/suppression) requirements, while respecting the historic‐district layout.

2. Pull‐Box (Alarm) Network o There are 10 pull boxes distributed so that every cluster of occupied buildings (administration, housing, shops, visitor facilities) has a pull station within roughly 100 ft.

o Each pull box is “hardwired” to an EOC (Emergency Operations Center) panel, and the blue handwritten table on the right confirms which “zone number” each P.B. reports into. In an emergency, if a pull box is activated, the EOC panel knows exactly which zone has gone into alarm.

o Key cluster examples:

▪ P.B. 1 (Zone 12) protects the southernmost workshop/housing near the Nisqually River (L-165).

▪ P.B. 7 (Zone 16) sits at the core, immediately adjacent to the Administration building (L- 001).

▪ P.B. 9 (Zone 18) and P.B. 8 (Zone 14) extend coverage into the northern and eastern housing areas (L-129/L-130/L-116).

3. Hydrant (Water) Network o Fifteen hydrant assemblies (H 1–H 15) guarantee that every major building cluster has a hydrant within 250 ft of the structure (NFPA 1 clear distance).

o An 8″ loop (bold line) encircles the main campus, feeding hydrants H 6, H 8, H 9, H 10, H 12.

o A 6″ branch runs east–west through the housing and shop clusters, feeding H 1, H 2, H 3, H 4, H 5, H 7, H 13, H 14, H 15.

o A few 4″ drain lines supply hydrants H 7 and H 11, primarily used as inspection drains or to serve a limited cluster (e.g., the building L-113/L-112 area or service building L-501).

4. Critical Intersections & Redundancy o The 8″ main (largest diameter) ties into the Administration Building (via H 6 & H 8), ensuring the “nerve center” has high flow.

o Hydrants H 9/H 10 on the west side protect the National Park Inn (L-600) and nearby staff housing.

o East and central clusters (housing, shops, radio equipment) are served from the 6″ main—H 2/H 3/H 4/H 5/H 7/H 13/H 14/H 15—creating a contiguous line of defense.

o If the 8″ main is ever shut down for maintenance, the 6″ branches maintain coverage for the core buildings, albeit at reduced flow—this redundancy is typical in historic sites where trenching additional 8″ lines would damage archaeological resources.

5. How This Ties to Fire‐Alarm Design o Every pull box is assigned to a “zone” number (1–10 in the table) that corresponds to the Emergency Operations Center’s panel zones. By cross‐referencing P.B. → Zone (handwritten table), dispatch/first responders immediately know which area has gone into alarm.

o Hydrants are collocated so that whichever zone goes into alarm can be visually triangulated (pull box + nearest hydrant) for rapid response.

o In a historic setting like Longmire, the main challenge is balancing historic preservation with code‐required coverage: no underground excavation can disturb known foundations, so hydrants are placed in existing roadways or graveled service lanes (hence the mixture of 8″, 6″, 4″). Pull boxes likewise are sited on poles and signposts to avoid surface pit excavation.

5. How to Use This Data in Fire Alarm Design

1. Alarm Mapping The pull boxes (P.B. 1–10) define exactly which zone in the EOC panel goes into alarm. For example, if a first responder sees “Zone 12,” they know immediately to dispatch resources to the southern workshop/housing near L-165.

2. Water‐Flow Coordination Every hydrant (H 1–H 15) is within 250 ft of its nearest building cluster. Because the campus is on a looped 8″ main (supplemented by 6″ and a few 4″ drains), there is built‐in redundancy: if any one main section is out of service, the next‐closest hydrant still provides at least 1,000 GPM of available flow (per typical 6″ main capacity).

3. Historic District Constraints Hydrants were sited so as not to trench through known archaeological/historic footprints (e.g., they run in existing gravels or roadways). Pull boxes are pole‐mounted or surface‐mounted rather than buried.

4. Zone–Hydrant Pairing In practice, once a pull box activates (e.g., P.B. 7 → Zone 16), dispatch will immediately send units to the nearest hydrant(s)—in this case H 6 and H 8—to begin a water‐supply setup. This pairing is essential in a remote historic campus where response times must be as short as possible.

In Summary

• Ten Pull Boxes serve ten distinct alarm zones (12, 10, 18, 15, 17, 13, 16, 14, 18, 14).

• Fifteen Hydrants (H 1–H 15) tap into a combination of 8″, 6″, and 4″ water mains.

• The “Loop + Branch” layout ensures that no single main shutdown leaves a building cluster without hydrant coverage.

• The accompanying handwritten table (in blue) on the right side of the plan translates each P.B.

number into its EOC panel zone, enabling precise decoding of an alarm event.

All of the above information can be used directly during the R&D phase of the Longmire Historic District Fire Alarm Design, ensuring (1) full zone coverage, (2) adequate hydrant placement for required flow, and (3) historic‐preservation‐compliant routing of both alarm circuits and water mains.

NOTES:

Pull Boxes

In the context of a fire-alarm system—especially a campus or historic district like Longmire—“pull boxes” are outdoor manual pull stations wired back to the central alarm panel. Key points:

• Function: When someone manually activates a pull box (by pulling down a lever or handle), it sends a discrete alarm signal into the fire-alarm control network. This effectively “breaks glass” in the field, alerting responders that a fire or emergency is present at that exact location.

• Construction & Location:

o Typically, a pull box is a weather-rated enclosure (metal or heavy-duty plastic) mounted on a post, pole, or building exterior so that it remains accessible in all seasons (snow, rain, etc.).

o It houses a simple, color-coded switch: when pulled, the switch closes a circuit that sends an electrical alarm back to the central panel.

o Because the boxes are outdoors, they often include a small clear protective cover (to prevent accidental activation) and are prominently labeled (“Fire Alarm Pull Station”).

• Wiring & Zones:

o Each pull box is hardwired (via a conduit containing fire-alarm cabling) back to the fire-alarm control equipment.

o In a multi-zone or multi-panel system, every pull box is assigned to a specific zone number (e.g., Zone 10, Zone 12, etc.). When that box is activated, the control equipment knows exactly “Zone X” has gone into alarm—enabling dispatch or Maintenance/Operations to pinpoint the location immediately.

EOC Panel

“EOC Panel” stands for Emergency Operations Center Panel, which in fire-alarm terminology is the main annunciator/control panel located within—or directly tied into—the building or campus Emergency Operations Center. Its main purposes are:

• Centralized Monitoring & Annunciation:

o All pull-box (and other field device) circuits terminate at this panel. When any pull box is activated, the EOC panel’s display will show which zone has tripped (often via a labeled LED, zone map, or graphical floor plan).

o Typical features include:

▪ Zone LEDs (or an LCD screen) indicating “Alarm,” “Supervisory,” or “Trouble” for each zone.

▪ Silence, Reset, and Acknowledge buttons so that authorized personnel in the EOC can manage alarms—silencing horns or strobes, resetting the pull-station circuit once the lever is closed, etc.

• Interface for First Responders:

o In many historic or large-area campuses (like Longmire), the EOC panel is the single point where park staff or emergency personnel gather to see the live status of all fire-alarm field devices (pull boxes, smoke detectors, water-flow switches, etc.).

o From that panel, personnel can immediately determine “Zone X is in alarm,” which correlates to a physical location on the map (e.g., Pull Box 7 at the Administration Building).

• Power Supplies & Supervisory Circuits:

o The EOC panel typically contains backup batteries (and sometimes even a small generator input) so it remains “live” during power outages—critical for fire safety in remote or historic sites.

o It also supervises all field circuits (pull stations, smoke/heat detectors, water-flow switches). If any conduit is broken, a device is shorted, or a wire is cut, the EOC panel will show a “Supervisory” or “Trouble” condition in that zone so that maintenance staff can correct it before an actual emergency.

How They Work Together in a Fire-Alarm System

1. Pull Box Activation → Signal to EOC Panel:

o Someone on campus sees smoke or fire and manually “pulls” the lever on a pull box.

o The pull box closes its internal switch, sending a notification (through its dedicated wire path) to the EOC panel.

o The EOC panel immediately identifies “Zone X” in alarm (e.g., “Zone 7”) and triggers local audible/visual alarms (horns/strobes) in that zone and any remote annunciators.

2. EOC Panel Response & Dispatch:

o Centralized staff or first responders at the EOC panel read off the zone number and consult a prepared campus map to find the exact pull box location.

o Simultaneously, the panel can automatically dial out (through a fire-alarm communicator) to a remote monitoring service or directly to dispatch, depending on the system design.

o The panel remains in alarm until staff acknowledge and reset it once the pull lever is closed and the fire is controlled.

3. Supervisory Monitoring:

o If any conduit run to a pull box is cut, or if the pull-station cover is tampered with, the EOC panel registers a “Supervisory Trouble” for that zone—alerting maintenance that that pull box circuit is no longer fully functional.

In Short

• A Pull Box is the field device (an outdoor, manually activated switch) that enables anyone on campus to initiate a fire alarm in a given physical location.

• The EOC Panel is the central control/annunciator where all pull-station circuits converge— letting responders know exactly which pull box (which zone) has gone into alarm, supervising all field wiring, and providing backup power to ensure 24/7 operability.

These two components work in tandem to guarantee that, in a remote or historic park setting like Longmire, any occupant can immediately report an emergency (via a pull box), and command staff can immediately identify, dispatch, and track that alarm through the EOC panel.
