MR28-9001/MR28-9002 Remote Dialer Modules
MR28-9121/MR28-9122  Remote City Tie Modules

Existing installations of model series MR-2900 or MR2920 fire alarm control panels that require the addition  of a digital dialer function or reverse polarity municipal  box (city) module can use these remote models without  impacting present cabinet space. These remote modules  mount close to the existing panel using a small cabinet  equipped with a locking door. Communication to the  control panel are via the external annunciator bus.

Dialer  Module  MR28-9001  provides  a  digital  alarm  communicating  transmitter  (DACT)  that  will  communicate alarm, supervisory, and trouble conditions  to a Central Station using Contact ID, SIA, or 10/20 BPS  communications formats. Three telephone numbers are  supported and test transmissions are fully programmable  including selectable power fail delay reporting.

City  Option  Module  MR28-9121/9122  supervises  alarm,  supervisory,  and  trouble  conditions.  Outputs  are selectable for Remote Station (Reverse Polarity or  Municipal Master Box (Local Energy Coil) operation.

Isolator Modules are required when the Dialer or City  Module is used on a system that also supports a serially  connected remote annunciator.

Programming  of  the  dialer  features  is  accomplished  using the convenient interface of the Secutron Modul-R  Human Interface programmer.

The MRDL Digital Alarm Communicator Transmitter (DACT)  module is added to the MR-2100 and MR-2200 system to provide Remote Station  monitoring  of  system  alarms,  troubles,  and  supervisory  conditions. Communications are available for : Contact ID,  SIA, or 10/20 bps formats. Use of the DACT module requires that two telephone lines  be provided for connection to the DACT. Service must be arranged with a Central Station monitoring facility for Remote Station Service. (MRDL is not ULC listed).
