Some of the integration the dvr holds the config, canging the camera will then be overwritten. Seen it on Adpro and HIK with ANPR

Have yuo set the integration up between the nvr and the camera. It may be overwriting the config in the camera

yes unless its a really old one then it was a link of wire iirc

the viper will flash like that its a 'comfort' led if you tap them again the led will stop for about 7 sec. Best to have them in this mode its like comfort leds on a bell, shows its powered

this is to give early warning of a connection issue failing device etc. good firms transmit this data and then book a visit 'before' the device fails. Low res is usually water or damage, high res is connection issues or failing detector

pts = push to set

Double balanced has 2+ resistors so a short or complete open circuit is a tamper. on a agalaxy you can add multiple door contacts and just ad a 1k in parallel with the switch. Basically a reading of 1k is closed 2k to 11k is alarm, 12k+ tamper But you cant use fault resistors etc. its a sensor fault. A grade 3 sensor can report a fault on the eol wiring by open different relays to give a fault reading. The panel can then identify that the sensor itself has reported it has failed an internal test. exit termsinators are to tell the alarm that everyone is outside the protected area and it can complete the arming process. Most people use final door but i prefer pts (terminate)

I'd say so

As Al says it should be looked after like you would a car, when was it last serviced? But is it the entry exit tones that have stopped working?

Qfa Also the output maybe open without a pull up or down it won't show much logic wise

id expect it to read a difference with a meter, unless the output is broken. If you cant read it with a dvm then a t relay wont help

i would think you would need a t-relay but yes unless you have overloaded it already

Agreed looks like the sounder is in supervision failure

To a point wire is wire but unless your running the lighting in it I'm a little lost?

Running perpendicular won't be an issue, as noted you need seperation too. But I don't see that in the pic? Would it not of been easier and better to be under the floor above?

What part of the UK are you based?

I rate the elmdene g3 contacts but do use the lst not the little ones

It will happen

There is no method to do 'variations' for intruder, there should be though. There was a lot of devices that were grade 3 dropped to grade 2 when the rear tamper rules changed

Technically you need to record the resistance of the circuit wiring. If eol that means without resistors etc and definitely not from the uncalibrated panel. Just as you need to do 70 on the motorway

As above if you use a grade 1 component on a grade 3 system the whole system becomes grade 1

Imo it should be a full default, God knows what your inheriting without

Not relevant to any member that has left

if this 0.25A fuse on the board id suggest its the wrong size

Yes you need to risk assess the site regarding what grade system the site needs, but many people just go 'grade 2 that will do' Grade 2 is cheaper than grade 3
