Mircom’s SIGSM-100 Signal and Speaker Silence Module is a compact electronic alarm appliance that is ideal for alarm signalling in individual rooms, apartments, hotels and offices where attractive appearance and dependable performance are prime concerns. The SIGSM-100 is used to silence a local alarm signal, such as a bell, horn or speaker (25V and 70V) within a suite. There are several applications for fully supervised or non-supervised bells, horns and speakers.
The SIGSM-100 Signal and Speaker Silence Module is equipped with a “Silence” push button and a red LED to indicate “active signal circuit” when lit. The push button allows the user to silence the local signals within the suite for a maximum of 10 minutes upon which the local signals will sound again until the signal circuit is inactive or the SIGSM-100 silence button is pressed again or the fire alarm panel is reset. Upon the fire alarm being reset, it takes approximately 45-60 seconds for the SIGSM-100
to reset. Silence of the controlled device(s) will not affect the other devices on the signalling circuits.
