those Johnson controls MS-2s are quite rare

Clinic #4 (location undisclosed)

Annunciators/panels:

<Unknown, presumably an EST3X, EST4, or EDGE series unit

Detectors:

<EST Signature Optica units (model unknown)

<ESL 425CT heat detectors carried over from an older system

<One Apollo heat detector (model unknown) outside an office entrance

<Unknown detectors–they’re similar to the ESL 522 but are beige-colored with a curved base going into the ceiling and no power indicator. These are also carried over from an older system and some of these devices are part of the hospital connected to it, which will be documented in a future post.

Pull stations:

<EST 270-SPO pull stations throughout the building

Notification appliances:

<EST Genesis speaker/strobes and speakers (white, ceiling-mount) throughout the building

<At least two EST Genesis speaker/LED strobes and LED strobes replacing broken Genesis units

<One EST Genesis speaker/LED strobe (red, wall-mount) outside in a courtyard area

<One System Sensor MASS2415ADA horn/strobe next to a telecom room entrance

Other:

<It isn’t known what the older system consisted of (outside of the detectors), but there are large rectangular and vertical plates scattered throughout, which suggests the previous NAs were horn/light combos.

Administrative Building #4 (location undisclosed)

Annunciators/panels:

<Notifier NFS-3030 with digital voice command plus separate cabinets for firefighter telephones and circuit boards/amplifiers. There was a previous system here, most likely a Siemens judging by several devices carried over.

Detectors:

<System Sensor 2WTA-B photoelectric units without bases carried over from the old system.

<Notifier FSP-851 photoelectric units throughout the building.

Pull stations:

<Notifier NBG-12LX units throughout the building; it isn’t know what the original pull stations, but they were most likely Siemens.

Notification appliances:

All of the Siemens devices from the original system were carried over and are as follows:

<S-LP(25/70)-MCS speaker/strobes

<SE-MC-CW speaker/strobes

<U-MCS strobes

<ZR-MC-CW strobes

<ZR-MC-W strobes

<One SET-MC-R speaker/strobe, presumably replacing a broken S-LP(25/70)-MCS

Hospital #5 (location undisclosed)

Annunciators/panels:

<The original system was likely from Simplex, judging by what was possibly leftovers of a 4207/4208 painted over in a lobby area.

<The current system consists of mostly Simplex 4100 and 4120 units throughout the building, plus 4100ES units replacing broken 4120s. When the 4100s go into alarm–at least for the attached office building–they start with two chimes, a voice-evac message for two or three rounds, then a continuous Simplex 4003 whoop tone until the system is audibly silenced, though sometimes, just the continuous whoop tone is heard depending on how the system is activated. When the 4120s go into alarm, they start with a 500hz continuous tone, then plays a message twice or thrice depending on where the alarm originated, then goes into a temporal 620hz chime until audibly silenced. For announcements, two chimes precede a voice-over. It isn’t known if the replacement 4100ES units go into alarm the same way as the 4120s.

<There is a fire suppression system in at least one part of the building that uses a Fenwal Net2000 unit.

Detectors:

<Simplex 4098 series (TrueAlarm) units throughout the building, at least one of which is mounted on a Simplex 2908 series base.

Pull stations:

<Simplex 2099 series units from different generations throughout the building.

<Blue STI push-button units for security responses throughout the building.

<One Reliable Security Group RMS series pull station (blue with hex lock) used as a cooling room door release.

<One Gaylord Industries C-1357A (rebranded AIP AI270-SPO; yellow with silver stripes) unit for the cafeteria kitchen fire suppression system.

<One round Ansul unit for the cafeteria kitchen fire suppression system.

Notification appliances:

<It isn’t known what the original devices were, but they most likely were Simplex horns, bells, or chimes. There are some square/rectangular plates scattered throughout the building denoting where the original devices were.

<During the 1980s, new and renovated units saw rebranded flush-mount Federal Signal 50GC-120-R speakers installed. One area has ceiling-mount flush-mount units still intact albeit disconnected, and some of the stairwells used surface-mount and flush-mount units, the latter of which had trim plates left over without the speakers themselves.

<The current devices on the system are as follows:

  1. Simplex 4902-9721 speakers
  2. Simplex 4903 series speaker/strobes and speakers, the latter of which are found only in stairwells.
  3. Simplex 4904 series strobes
  4. Simplex 4906-9102 strobes
  5. Simplex 4906 series (TrueAlert) speaker/strobes and strobes in newer/renovated sections.
  6. Simplex 4906-9254 strobes
  7. One tan, wall-mount cylindrical speaker in a first-floor stairwell (make/model unknown).
  8. One Edwards AdaptaBeacon with a red strobe outside a cooling room entrance.
  9. One Wheelock MB-G6-24-R bell used as a sprinkler alarm (set to continuous).
  10. One Wheelock RSS ‘Agent’ strobe used for the Fenwal fire suppression system.
  11. At least one Wheelock E50-24MCW-FR speaker/strobe that most likely replaced a TrueAlert in a renovated office area.

Other:

<One flush-mount Edwards 89STR-A-AQ strobe outside an unused guard shack.

<DSI ES4200 series door alarms next to several office entrances.

Hospital #6 (location undisclosed)

Annunciators/panels:

>Unknown, presumably one or more Faraday VPS series voice-evac panels judging by the devices below, but they could also be one or more National Time & Signal Corporation (Natsco) Super 7000 series voice-evac panels.

Detectors:

>System Sensor 1424 ionization units throughout the building.

>One System Sensor 2151 series photoelectric unit replacing a 1424.

Pull stations:

>One Faraday F1GGT unit in the main lobby.

>Natsco Type 641 units throughout the building, many of which were mounted at pre-ADA levels and presumably replacing the original units.

>EST SIGA-278 units replacing some 641s.

Notification appliances:

>One Faraday 2958 speaker/strobe in the main lobby.

>Faraday chime/strobes or speaker/strobes with flush-mount plates and the cylindrical strobe design throughout the building–these would all have been from the 1990s.

>One Veeder-Root overfill alarm unit outside of a mechanical room.
