Description
The Releasing Device Modules, Models RM-30U and
RM-30RU are designed to operate and supervise
solenoid valves or relays used for release of
extinguishing systems and to operate and supervise
relays used for door closing/opening or fan control.
The RM-30U and RM-30RU are functionally the
same except that the RM-30RU incorporates three
(3) series resistors that are used to adjust the
resistance of the circuit to compensate for varying
numbers of solenoids.
Release logic and subsequent activation of the
modules are governed by appropriate zone and
control modules in the System 3 control panel.
The modules are suitable for continuous duty when
used with continuous duty solenoids.
Dual input signals are required for activation of these
modules and a release takes place when a high
going signal is present on both of the input terminals.
These input signals are compatible with the outputs
available from the System 3 zone and control
modules. All agent release logic, time delays, etc.,
are performed ahead electrically of the RM-30U/
30RU by utilizing such System 3 modules as : ZU-35
Zone Module, PM-31 Program Matrix, TL-30U Timer,
and SR-32 Relay Module. The separate release
power input terminals extend the modules’ versatility
and reduces the load on the 10 conductor system bus.
A circuit disconnect switch is provided to deactivate
the module during servicing of the system. When the
switch is in the off position, a local supervisory LED
will be illuminated and an audible will sound.
The modules are provided with a yellow LED trouble
indicator to show an open release circuit condition
when the system is not in alarm. The LED indicator
can be lamp tested from the control panel. In addition
all wiring is monitored by the control panel for ground
faults. The module is also provided with a
supervisory LED, buzzer and silence switch. As
noted above, activating the disconnect switch
activates the supervisory signal. When there is no
disconnect condition and the supervisory silence
switch is in the silence condition, a trouble signal is
activated. The modules are placement supervised,
providing a trouble signal on removal from the
system.
Electrical Information
Module current requirement:
Normal supervisory - 6mA @ 24VDC
Released energized - 1.5A maximum @ 24VDC
Maximum line resistance - 3 ohms for typical
approved load.

NOTES for RM-30RU:
1. Operating solenoids, relay, or other approved loads operate
from a 24 VDC source. Use Battery Transfer Modules BC-35
or DC Program Plug JP-D in P2 of the CP-35.
2. The RM-30RU Releasing Device Module may be used to
activate up to four 6 VDC solenoids. Table 1 describes the
only acceptable combinations of solenoids and/or resistors.
Any other combination not described in Table 1 is not
permitted.
3. Solenoid supervised for open only.
4. All terminals are non-power limited. For wiring instructions
refer to the EB-31/-32/-33/-35 Installation and Power Limited
Wiring Instructions, P/N 315-093680. If power limited wiring
is desired use the PLM-35, P/N 315-093495.
5. For releasing diagram connections of RM-30RU, refer to
P/N 315-049675. The abort switch can have precedence
over the manual release function, or the manual release can
have precedence over the abort switch.
