Channel HARK 1 Pull Cord is supplied with a red plastic ring. An extra ring is supplied to conform to ‘Approved Document M’. The second ring should be fitted lower down near floor level. Activating a call is simply made by pulling the cord. This will activate the re-assurance indicator on the pull cord unit. In turn this will also illuminate the reset unit and trigger the internal sounder. At the same time the overdoor indicator/sounder unit will illuminate and trigger its own internal sounder.
