Does the gas detector (Maretron part LP-200012UL) have a power supervision relay?

Although some of Maretron’s SIM100 accessories have built-in power supervision relays like the smoke/heat detector (Maretron part number SH-002) and carbon monoxide detector (Maretron part number CO-CO1224T), the gas detector does not have a built in power supervision relay. However, power monitoring can be added to the gas detector using an external power supervision relay.
