Addressable Relay Module with One Form C Output Contact on a Single SLC Loop Address for Fire Alarm Control Applications
The Potter PAD100-RM is an addressable fire alarm relay module that provides one Form C relay contact output while consuming only a single SLC loop address. The relay output allows the fire alarm panel to control external devices such as door holders, HVAC fan shutdowns, elevator recall circuits, and damper actuators through programmed automation sequences. The PAD100-RM uses the PAD protocol for addressable communication on the SLC loop, with a standby current of just 240 microamps to keep total loop power draw low across large systems.
The PAD100-RM is part of the Potter PAD100 Series of addressable modules and shares the same compact 4.17 x 4.17 x 1.14-inch housing as the monitor modules in the family, mounting directly to a standard 4-inch square or double gang electrical box. The Form C relay contact is rated at 2 amps at 30VDC and 0.5 amps at 125VAC, handling the load requirements of common fire alarm control applications. A red LED flashes during normal panel polling to confirm communication status, and up to 127 PAD100-RM modules can be installed on a single SLC loop. The module operates on 24V DC from the SLC loop and is compatible with Potter IPA Series fire alarm panels.
Where the PAD100-RM Fits
- Commercial buildings with HVAC shutdown and door holder release requirements where the fire alarm panel needs to switch external circuits at specific locations, the addressable relay output ties directly into programmed automation sequences, and the single SLC address conserves loop capacity across buildings with dozens of control points
- High-rise towers and healthcare facilities with elevator recall and damper control where code-required automation depends on relay outputs at specific floor and zone locations, the 2-amp contact rating at 30VDC handles elevator recall relays and damper actuators, and the compact housing fits inside standard electrical boxes alongside other fire alarm modules
- Industrial and warehouse facilities with zone-specific equipment shutdowns where the fire alarm panel controls exhaust fans, process equipment interlocks, or access control releases through relay modules at each zone, the PAD protocol communication maintains reliable control across long SLC wire runs, and the 32 to 120 degree Fahrenheit operating range handles mechanical room environments
What the PAD100-RM Delivers
- Form C Relay Contact Output: One Form C (SPDT) relay contact rated 2A at 30VDC and 0.5A at 125VAC. Controls door holders, HVAC shutdowns, elevator recall, damper actuators, and other fire alarm automation outputs using a single SLC loop address.
- Low-Current Addressable Communication: 240 microamp standby and alarm current on the SLC loop minimizes power draw across large systems. PAD protocol communication with red LED status indicator that flashes during panel polling. Up to 127 modules per SLC loop.
- Compact Mounting: 4.17 x 4.17 x 1.14-inch housing mounts to a standard 4-inch square or double gang electrical box. 24V DC operating voltage from the SLC loop. Operating temperature range of 32 to 120 degrees Fahrenheit with humidity tolerance to 93% non-condensing.
- IPA Panel Compatible: Integrates with Potter IPA Series fire alarm panels for addressable relay control across the SLC loop. Same PAD100 form factor as the SIM and DIM monitor modules for consistent installation across the system.
What Is a Fire Alarm Relay Module
A fire alarm relay module is an addressable output device that allows the fire alarm control panel to switch external circuits and equipment in response to alarm conditions or programmed automation sequences. When the panel activates the relay module, its Form C contact changes state to energize or de-energize a connected load such as a door holder, HVAC fan, elevator recall circuit, or smoke damper actuator. The PAD100-RM provides this relay output on a single SLC loop address with a contact rating of 2 amps at 30VDC, making it the right choice for control applications where the panel needs to directly switch low-voltage equipment at specific points throughout the building.
