INTERIOR SENSORS AND CONTROL DEVICES
**************************************************************************
NOTE: Show sensor patterns and installation details
on drawings. Add requirement for additional site
specific conditions such as furniture/equipment
layout within protected areas, hazard location area,
type of hazard, class, and group. Remote test
capability should be used only when required by
governing regulations or when sensors are installed
in hard to reach areas. Within the U.S., the FCC
regulates the operating frequencies of all microwave
sensors. Other countries have their own
frequencies. The designer must determine what
frequency is allowed at the project site.
**************************************************************************
Interior sensor housing shall provide protection against dust, falling
dirt, and dripping noncorrosive liquids.
2.6.1
Balanced Magnetic Switch (BMS)
The BMS shall detect a 6 mm 1/4 inch of separating relative movement
between the magnet and the switch housing. Upon detecting such movement,
the BMS shall transmit an alarm signal to the alarm annunciation system.
2.6.1.1
BMS Subassemblies
The BMS shall consist of a switch assembly and an actuating magnet
assembly. The switch mechanism shall be of the balanced magnetic type or
triple-biased reeds to provide detection of tamper attempts. The switches
shall provide supervision and pry tamer capability. Each switch shall be
provided with an overcurrent protective device, rated to limit current to
