Knight Grade 3, 8 Core Flush Contact with Integral Resistors, Stainless Steel Plate

The YA90 is a potted white flush contact, complete with 1 metre of 8 core cable. This contact is fits a 25mm diameter recess and operates at a gap of approximately 20mm. The plate is oval, of stainless steel construction and takes an area of approximately 32x58mm. A dedicated tamper reed in the housing provides magnetic interference detection, meeting the requirement for Grade 3. EOL Resistors: 1k, 2k2, 4k1, 4k7, 5k6. Alm Resistors: 1k, 2k2, 4k1, 4k7, 5k6, 6k8. These resistors cover the majority of leading panel manufacturers including Honeywell, Texecom, HKC, Risco etc. YA90 is unsuitable for 4-wire installations. The integral resistors must be used in the circuit. Two YA90 contacts can share a zone, depending on the configuration of the alarm panel (see instructions). YA90 comes complete with fitting screws for immediate installation from the package. - Resin sealed against outside attack - Operating gap: ~20mm - Fits 25mm diameter recess - Oval, stainless steel plate - Supplied with fitting screws - Integral resistors
