Expansion module for detectors and arming devices
Ottobrunn, Germany
Bosch is expanding its LSN product portfolio with a new expansion module that allows conventional detectors and contacts to be connected to an LSN loop. Typical applications also include connecting arming devices such as block¬-type locks and coded arming devices and their components to an LSN loop. The inputs can be configured for intrusion, tamper and door locking detection as well as other detection types. In addition, the module provides four programmable -outputs, e.g. for controlling a block-type lock, or a logical arming device.
In local security networks, detection and control functions are performed via the LSN line. This means additional inputs in the control panel are not required for control procedures. Conventional detectors and contacts, magnetic contacts or bolt contacts are grouped together on one detector zone. The expansion module provides six conventional inputs. Two inputs are designed for line-fed glass -break detectors, two are intended to connect a block-type lock or a coded arming device.
Bosch developed the expansion module for connection to the next generation of LSN improved control panels. The device offers the extended functionality of LSN improved technology. The integrated DIP switch can be set to LSN classic mode, which provides backwards compatibility to existing Bosch LSN classic mode control panels, such as NZ 300 LSN, UEZ 2000 LSN and UGM 2020.
The expansion module is available in two versions: ISP-EMIL-120 with enclosure and ISP-PCBA-EMIL as module only. A maximum of¬ two IMS-RM relay modules can be installed in the enclosure of the ISP-EMIL-120 version. This relay module is necessary to connect control elements with high current requirements or when potential-free switching is required. One IMS-RM relay module includes two relays, each of which has two switch contacts for potential-free outputs.
The expansion module operates particularly reliably, thanks to the encapsulated electronics. The built-in buzzer can be used to signal status changes, for example in the event of maintenance. As a security precaution, the module includes a tamper contact that, if triggered, sends a unique message and is assessed as a tamper alarm. Bosch offers an optional MS-WTC wall tamper switch to trigger a tamper alarm if the device is removed from the wall. The IMS-WTC switch mounts inside the enclosure of the ISP-EMIL-120 version,
All LSN elements are designed to loop through the power supply of subsequent LSN elements. The applicable voltage range must be taken into account to ensure correct operation of the expansion module. The detector voltage should be between 9 and 30 V.
