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 mod-
ules 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 trouble condition LED will be illuminated.
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 modules are placement super-
vised, providing a trouble signal on removal from the system.
