Fire Alarm Activation #9

Older mechanical horn/strobes sounding on a Siemens system at a hotel. Many of the older devices in this system sound rough or aren't working at all. There are plans for the hotel to get renovated, and these devices will likely get replaced in the process.
Components (all Siemens/Pyrotronics):
MXL series FACP (?)
HSD-24F (Wheelock 7001T) Horn/Strobe
U-MHU-MCS Horn/Strobe
OOH941 Detector with ABHW-4s Sounder
MSI-10B Pull Station
Signal coding is continuous for the HSD-24s and temporal (code 3) for the U-MHUs. Strobes are synchronized on U-MHUs, but HSD-24F strobes are not compatible with strobe synchronization. Regardless, these older horn/strobes are wired up to the synchronized NAC.
Below components are not seen in this video.
SSD-C Annunciator
AS-75-R-WP (Wheelock AS-WP) Outdoor Horn/Strobe
Wheelock MT-24-LSM Horn/Strobe [possibly rebranded by Siemens/Pyrotronics]
Wheelock LSM-24 (single-gang) Strobe [possibly rebranded by Siemens/Pyrotronics]
FP-11 Detector
There may be a PAD-3 in this system too.
Outro Image: Wheelock 7002T-24 Horn/Strobe attached to a crooked backbox in a medical building.

Nice to see mechanical horns still in use even if they are gonna be replaced soon.

[@EncryptingJava]

Yeah I agree.
Several places are switching over to voice evacuation because there seems to be more rules about that. Almost seems like a requirement for more places.

[@vintagesimplexfirealarmsof6440]

​@EncryptingJava my area still uses mechanical horns to this day or older systems

[@Warp3326]

same they work just as good as voice@@vintagesimplexfirealarmsof6440

I really find it funny on how the horn strobes make funny sounds

[@BRISTOLFORCE2009]

3:05 that one sounds amazing

[@bjthedjdutchdude1992]

This hotel has all kind of horns except mini horns.

[@ThatOneExoRailfan]

0:45 - Horn needs to be tuned or replaced if not working

[@anthonymeza7519]

Those alarm need to fix

[@michaelgatien4277]

Except for those smoke alarms and a few Siemens UMMTs, they were mostly 7001Ts. A few sound quiet, sick weird or too fast. Are those comprised horn/strobes going to be repaired soon?

[@michaelgatien4277]

At 2:23, it sounds very similar to the one in this video of a 7002t.

I heard this hotel will be getting renovated soon, so these will likely get replaced.

[@ThatOneExoRailfan]

@@dewpoint8900 you should get the alarms from there when replaced

@@ThatOneExoRailfan Sounds nice, but sadly I no longer attend PSU.

[@SirensAndAlarmsOfNorthernIL]

Those 7001Ts tho

[@CentralVirginiaEAS]

what caused the hotel fire alarm activation?

[@dewpoint8900]

This was a drill. The hotel was being used as a student dormitory at the time.

[@AlessandrasFunPlace]

What Fire Alarm And Tone Is That That Is Pretty Interesting 🙂 2:21

[@dewpoint8900]

That's a Pyrotronics HSD-24F (a rebranded Wheelock 7001T).

[@AlessandrasFunPlace]

@@dewpoint8900 Thank You 😊

[@vintagesimplexfirealarmsof6440]

was the panel a mxl or different siemens one

[@dewpoint8900]

Not sure, all I know is there's an SSD-C annunciator at one of the entrances.

[@Firealert101]

Must be conventional

[@jonathanstarling1082]

Where is this?

[@dewpoint8900]

Nittany Lion Inn at Penn State

[@GaryBeltz]

Which devices are doing the low frequency sound?

[@dewpoint8900]

The smoke alarms in the rooms, there's a picture of one at the beginning.
