CQR Grade 2 Door Contact, Large Surface, 6 Terminal, White SC570/WH/G2/EN
About this product
The CQR SC570/WH/G2/EN is a grade 2 door contact for windows and doors on domestic and commercial alarm circuits. It is a large surface mounted magnetic contact in white, suited to places where a standard contact is not big enough. It has 6 terminals and a separate tamper circuit.
Key features
- Room for movement – makes within Min Close 36mm and opens by Max Open 65mm on the X axis, on non ferrous surfaces
- Tamper on its own circuit – separate tamper circuit, with tamper connections on the terminal block
- Spare terminals for tidy joins – 6 terminals, with two marked N/C, not connected (spare)
- Optional wall tamper – detection of removal from its mounting surface, if required
- Works on pairs of doors – suitable for double door applications
- Long switch life – life expectancy >1,000,000 cycles, with a rhodium contact
For installers
- Power: contact rating 500mA @ 12Vdc, contact resistance 100 milliOhms.
- Mounting: contact 85 x 25 x 21 mm on 72mm centres, magnet 85 x 18 x 21 mm on 40 centres.
- Cabling: two snap out cable entries at either end, plus holes for rear cable entry.
- Compatibility: double pole or fully supervised wiring, with R1 and R2 to suit the control panel.
- Standards: designed to meet EN50131-2-6:2008 Grade 2 and environmental class II, certified by Telefication.
Frequently asked questions
What grade is it?
Grade 2. It can be used in installations up to and including grade 2, and is certified to EN50131-2-6:2008.
What gap will it work across?
The circuit makes within Min Close 36mm on the X axis and Min Close 27mm on the Y axis. It opens by Max Open 65mm and Max Open 60mm. These are approximate figures on non ferrous surfaces, and mounting on a ferrous surface will reduce them.
Can it be fitted outside?
No. It is certified to environmental class II, which is for use indoors.
Does it have resistors built in?
No. In the fully supervised layout, R1 and R2 are fitted to suit the control panel.
Will it work on double doors?
Yes. It can be wired double pole or fully supervised on two doors.
What happens if the wall tamper screw is fitted and the contact is pulled off?
The circuit board breaks, and this is irreversible. The contact will need to be replaced.
