Signature Series Riser Monitor Module (RM1) 1 / 3
Signature Series
Riser Monitor Module (RM1)
Product description
The Signature Series Riser Monitor Module (model RM1) is an
intelligent analog-addressable device that monitors the integrity
of:
• 12 and 24 Vdc circuits
• 25 Vac circuits
• 70 Vac circuits
• Telephone riser signals
Once device address is required. Upon the loss of a signal, the
fire alarm control panel indicates an alert status. See Table 1
for a list of model numbers.
The loop controller assigns an address to the RM1
automatically. A custom address can also be assigned to the
module via laptop computer. No addressing switches are used.

Mounting
The RM1 can be mounted in a North American 2-1/2 in (64
mm) deep 2-gang box or a standard 4 in square box 1-1/2 in
(38 mm) deep with 2-gang cover. The terminal blocks accept
12, 14, 16, or 18 AWG wire (2.5, 1.5, 1.0, or 0.75 sq mm).
Sizes 16 and 18 are preferred.
System controller compatibility
The RM1 requires the Signature loop controller. The loop
controller downloads the personality code which determines
how the module operates. The following personality codes can
be downloaded to the RM1.
Personality code 23: Riser monitor (factory default):
Personality code 23 configures the RM1 to monitor 70 Vac
audio, 25 Vac audio, or 12 Vdc and 24 Vdc risers. A trouble
condition is reported back to the panel wherever the voltage on
the riser drops below the trouble threshold.
Note: The hardware jumper on the RM1 must be configured
for either 70 Vac or 25 Vac / 24 Vdc / 12 Vdc.
Personality code 24: Telephone riser monitor: Personality
code 24 configures the RM1 to monitor telephone risers. A
trouble condition is reported back to the panel whenever
voltage on the riser drops below the trouble threshold.
The delay time from when the device falls below the trouble
threshold to when it sends a trouble signal to the panel is user
definable in the appropriate data entry program. A delay of 5 to
75 seconds can be assigned to the device; the default delay
period is 15 seconds.
Warnings
1. Disconnect power to cabinets before installing or removing
components. Failure to do so may result in serious injury
or loss of life. Dangerous voltages may be present at the
terminals even when power is shut off.
2. This module will not operate without electrical power. As
fires frequently cause power interruption, we suggest you
discuss further safeguards with your local fire protection
specialist.
3. This module does not support conventional smoke
detectors.
