Don't know about the hardware pricing, but the pro svcs line seems excessive by a factor of at least 2.

That's what I thought but total bill was the lowest of three bidders.

Our BDA guys are not particularly enarmoured with Comba, but it sells because of the lower price point.

Me thinks these guys are crooks. Remove bda and rewire....3-4 hours TOPS. Carry non penetrating mount to roof, assemble and wire 4-5 hours. Replace 8 batteries 2-3 hours.

2 guys one day labor isnt $10k...not even two days.

If theyre not crooks they're mighty proud of their company.

Why does antenna have to be moved?

Also why 8 batteries? The most ive ever seen in a mfg battery box is two?

If they are on the roof, maybe 80% of the Labor/Professional Services: $9,680.00 pricing is liability insurance..

Is that true? Comba isn't a UL listed BDA? What kind of problem does that create? This upgrade is mandated by the City for the FD.

Someone mentioned this to me the other day. I haven't looked at it. It was a vendor actually who said it. When I see him again in another few weeks I'll ask for clarification.

I don't see anything in the proposal that says they get to keep the old equipment. Does it have any value?

I'd snag the filters out of it at a minimum. Good quality broad hi Q filters like that aren't cheap. Can be useful in front of an sdr etc.

Since Axell equipment is orphaned at this time (that may change), if this BDA is still functional, it may be valuable as spare parts for someone else. If you aren't bound by public auction rules, you could try to move it on fleabay.

I always tried to keep the old equipment. You never know when you can use it as a emergency backup or upgrade somewhere else. Of it turns out to be garbage I can always throw it out myself.

So I got a comba cut sheet in for a new bda today... It's not certified as a bda. It's UL certified for "information technology equipment" It doesn't appear to be certified to UL2524... prove me wrong lol

"Complies with NFPA 1221 2016 / 2019 edition, IFC 2018 Section 510 • FCC: PX8RX-7W22-A, IC: 11919A-RX7W22 (Class A) • FCC: PX8RX-7W22-B, IC: 11919A-RX7W22 (Class B) • UL 60950-1 & UL 60950-22 Standards Certified – SGS Certificate No.: SGSNA/17/GZ/00139"

UL 60950-1 Standard on Information Technology Equipment Safety​

The UL 60950-1 standard is applicable to mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a rated voltage not exceeding 600 V and designed to be installed in accordance with the Canadian Electrical Code, Part I, CSA C22.1-09; General Requirements - Canadian Electrical Code, Part II, CSA C22.2 No. 0-10; the National Electrical Code, NFPA 70-2008; and the National Electrical Safety Code, IEEE C2-2007. The standard is also applicable to equipment designed to be installed in accordance with Article 645 of the National Electrical Code, ANSI/NFPA 70, and the Standard for the Protection of Information Technology Equipment, NFPA 75-2009. The original date of publication was March 27, 2007, with the last revision on December 19, 2011.

The UL 60950-1 standard is applicable to information technology equipment designed for use as telecommunication terminal equipment and network infrastructure equipment, regardless of the source of power. The UL 60950-1 standard and tests take into account not only normal operating conditions of the equipment but also likely fault conditions, consequential faults, foreseeable misuse and external influences such as temperature, altitude, pollution, moisture, as well as overvoltages on a mains supply, telecom network, or cable network.

The UL 60950-1 standard is also applicable to components and subassemblies intended for incorporation in information technology equipment. It is not expected that such components and subassemblies comply with every aspect of the standard, provided that the complete information technology equipment, incorporating such components and subassemblies, does comply.

The UL 60950-1 standard specifies requirements intended to reduce risks of fire, electric shock, or injury for the operator and layman who may come into contact with the equipment and, where specifically stated, for a service person. User is the term applied to all persons other than service persons. Requirements for protection should assume that users are not trained to identify hazards, but will not intentionally create a hazardous situation. Service persons are expected to use their training and skill to avoid possible injury to themselves and others due to obvious hazards that exist in service access areas of the equipment. UL 60950-1 verifies information about potential hazards is marked on the equipment or provided with the equipment, depending on the likelihood and severity of injury, or made available for service persons. In general, users shall not be exposed to hazards likely to cause injury.

Interesting. The vendor is installing this equipment in a high rise to meet City requirements for FD comms in the building.
