Autonomous lighting/security alarm installation having lighting unit remote control line connected and break glass alarm switch parallel connected generating pulse alarm detected above set level

摘要

The autonomous security lighting has a lighting unit (27) connected to a remote control line (5) and an alarm module (25) providing an alarm message. There is an alarm command pulse detector (33) in parallel with the command module detecting pulses above a first determined level (31). The alarm module is in parallel with the alarm command line (17) which is set by breaking a glass switching mechanism (19) in series with a shunt resistance (21), and setting the pulse alarm generator (31).
