EQ25xxaRm agent Release module
The EQ25xxARM Series Agent Release Module (ARM)
(see Figure 2-15) provides agent release or deluge
pre-action capability. The device is controlled by
programmable logic in the Controller. Time delay,
abort and manual release sequences allow the device
output to be programmed for use in unique
applications.
The device is field programmed to operate in one of
the following modes:
Timed–
Output is activated for a field
selectable duration from 1 to 65,000
seconds.
Continuous– Output latches until reset.
Non-latching– Output follows the input.
The device can monitor and control two output
devices (24 vdc rated) that are programmed and
energized together. The release circuits are
compatible with a variety of solenoid or initiator based
suppression systems.
The release circuit is supervised for open circuit
conditions. If a trouble condition occurs (open circuit
or solenoid supply voltage less than 19 volts), it will
be indicated at the Controller. Each output is rated at
2 amperes and auxiliary input terminals are provided
for additional 24 vdc output power where needed.
note
For deluge and pre-action applications, the input
voltage to the ARM or DCIo must be 21 VDC
minimum with connection to any solenoid listed
in table 2-6 or 2-7. Wiring must be in accordance
with the listed maximum wiring lengths.
Refer to the EQ25xxARM Specification Data sheet
(form number 90-1128) for additional information
