Provide sensors that have a local means of indicating detection for use during installation and calibration with a means of disabling the indication. The sensor is to have an LED walk test indicator which is not visible during normal operations. When visible, the walk test indicator will light when the sensor detects an intruder. Provide a sensor equipped with a manual control, located within the sensor's housing, to enable and disable the test indicator or with the test indicator located within the sensor housing so that it can only be seen when the housing is open or removed.

One second is the minimum amount of time required to depress or defeat the tamper switch after opening or removing the cover. Enclosure and tamper switch must prevent direct line of sight to internal components and prevent switch or circuit tampering. Conceal mounting hardware so switch cannot be observed from enclosure exterior. Tamper switches on doors which are opened to make normal maintenance adjustments to the system and to service power supplies must [not] have a maintenance position.

iv. Spring-loaded and held in the closed position by the door, or cover protected.

v. Wired to break the circuit when the door or cover is disturbed.

vi. Wired so that each sensor and device is annunciated [individually] [by zone] at the central reporting processor.
