Looks like a conventional heat detector i.e. non-addressable

Thank you RG. It’s connected to the alarm and does go off if there’s smoke from cooking but not sure if it’s heat detector as well.

Is it in an apartment, if so it would set off the building/landlords fire alarm system.

There is a red LED light that will illuminate if this detector activates and all the buildings fire alarm will sound.
To comply with building regs only a heat detector from the building fire alarm system shall be installed in an apartment.
The apartment should be protected by a domestic mains powered smoke/heat alarm
if only the internal apartment smoke alarms are going off then it is not this detector.

Would that be current regs, only a wired heat and standalone smokes

I'd be surprised

Not for apartments L3X plus domestic.

Reason being to avoid false activation of the landlord system caused by cooking for example. Domestic system now includes bedrooms, so a nice bit of stuff to go into apartments now.

The photo is a menvier heat detector (without sounder). It could be addressable or conventional, both look the same without taking down.

Yes, bedrooms must be covered in a domestic system since 2013.

Yes

Not a great setup the heat alarm connected to the panel

Fire is advanced by the time the panel goes off

There's multi-stage alarms that will activate the panel after a while, they sound in the apartment
first

So guys please excuse my ignorance but if this is a mains connected heat detector which is connected to the panel, do I need a smoke alarm also connected to the mains/panel?

The heat detector is to protect the landlords escape routes. It is always mounted inside the front door to the apartment. That door will be a fire door protecting the common corridors. This will allow the rest of the building occupants to evacuate before the fire door is compromised.
The domestic smoke alarms protect the individual apartment users, bit should something have happened them eventually the heat detector will operate and allow everybody else to evacuate.
Thats the the design anyway.

There are these systems, but they don’t really comply. The domestic and landlord systems should be fully separate. You are of course correct that the block system will be delayed in the event of a genuine fire. But it’s a trade off between that and a reduction in confidence in the system caused by false alarms. Apartments should have 60min fire separation to the rest of the block.
