The DS100 door sentry series latching annunciator is designed for audio+visual alarm indications of an opening or a closing of a dry contact, or for other emergency-call or panic type applications.

When a remote contact switch is activated, the DS100 annunciator will sound an electronic alarm (tone) and will light, indicating the location of the alarm. The tone signal can be silenced at the master station (and/or at the optional ir019b remote alarm indicator). The individual switch/light will remain lighted until the remote switch is reset, and the master switch is depressed twice, resetting the light at the master annunciator.

The DS100 is known as a 'latching type annunciator', since the individual lights 'latch' (remain lighted) until individually reset or all are reset by an optional key switch.

The DS100 master annunciator is modular and can be flush, surface or desk mounted, and is available in any size, in multiples of four (4) lights/switches. The DS100 features built-in tone signal speaker, and tone silence button and light.

You can even add pocket-paging capability as well, to signal staff members that are away from the master station(s).
