Specifications
Principle
This information is included with the module as a quick reference installation guide. Refer to the control panel manufacturer’s installation manual
for more detailed system information. If this module will be connected to an existing operational fire detection system, inform the building occupant
or owner and local authority that the system will be temporarily out of service. Disconnect power from the communications loop before installing
this module.
General Description
The
M500DMR
multi input-output module
is capable of replacing two Class B monitor modules and two individual relay control modules on an
intelligent fire alarm loop. Each monitor input is intended to interface between a fire alarm control panel and one or more devices. Each relay output
is intended for Form C switching applications which don’t require wiring supervision for the load circuit.
Each monitored input has its own red LED, which can be controlled by the control panel. Each relay output has its own red LED, which can be
controlled
by the panel as well.
The module address is selected by means of rotary decade address switches (See
Figure 1
). These can be accessed either from the front or the top of
the module. A screwdriver should be used to rotate the wheels to select the desired address.
Each module can use up to four (4) addresses. The
base
address selected via the rotary address switches will be assigned to relay output #1 (R1) from 0
1
to 96. The module will automatically assign the next three addresses as appropriate to monitored input #1 (I1), relay output #2 (R2) and monitored
input #2 (I2).
If monitored
relay output #2 (R2)
and /
or
input #2 (I2)
are not used, please switch the corresponding DIP switch to the ‘OFF’ position with
a
screwdriver
(See
Figure 1A
). These two addresses will then be free to be used for other devices on the loop.
This module can be used as an automatic switch which open circuits the line if the communication line voltage drops below 4 volts. If the line
voltage rises above 7 volts the product will detect the removal of the fault condition and restore power to the product automatically.
Installation
Note: Module
M500DMR
must only be connected to control panel using
compatible proprietary analogue addressable communication protocols
for monitoring and control.
The module can be mounted in two ways
(
See Figure 3
).
